Detailed Description
Further advantages and effects of the present invention will become apparent to those skilled in the art from the disclosure of the present invention, which is described by the following specific examples.
It should be understood that the structures, proportions, sizes, etc. shown in the drawings are for illustration purposes only and should not be construed as limiting the invention to the extent that it can be practiced, since modifications, changes in the proportions, or otherwise, used in the practice of the invention, are not intended to be critical to the essential characteristics of the invention, but are intended to fall within the spirit and scope of the invention. Also, the terms such as "front", "rear", "left", "right", "middle" and "a" and the like are used in this specification for convenience of description only and are not intended to limit the scope of the present invention, but rather the relative changes or modifications thereof are considered within the scope of the present invention without substantial modification of the technical content.
Firstly, in the industry, a metal plate, such as a titanium plate, is rolled by a rolling mill, and in order to obtain the metal plate with a specific thickness, the rolling is required to be repeated for a plurality of times, namely, the number of times of the rolling process is referred to as a number of times of the rolling process, wherein the number of times of the rolling process is one in the first rolling process, and the number of times of the rolling process is two in the second rolling process; when multi-pass rolling is performed on the same rolling mill, the metal plate moves back and forth in the rolling mill, for example, in some scenes, the rolling pass is one, the metal plate enters the rolling mill from the front end of the rolling mill, the metal plate exits the rolling mill from the rear end of the rolling mill, and when the rolling pass is two, the metal plate enters the rolling mill from the rear end of the rolling mill and the rolling mill from the front end of the rolling mill, and the steps are repeated to realize multi-pass rolling.
In an embodiment, referring to fig. 1, the application exemplarily shows a titanium plate low-temperature rolling purging method, which is applied to a multi-pass rolling process of a rolling mill on a target titanium plate, wherein the target titanium plate is a titanium plate needing to be rolled and purged, and the method comprises the following steps:
step S110, performing temperature detection on target areas at the front end and the rear end of the rolling mill to obtain temperature parameters, and adding a corresponding position label to each temperature parameter, where the position label at least characterizes the position of the target area for obtaining the temperature parameters.
For step S110, temperature detection is performed on target areas at the front end and the rear end of the rolling mill to obtain temperature parameters, it is to be understood that the front end and the rear end are two ends of the target titanium plate entering and exiting the rolling mill respectively, the target areas refer to areas selected from the passing path of the target titanium plate before and after rolling, purging of the target titanium plate is completed in the target areas, the target areas are defined in advance according to a purging mode, for example, in some embodiments, compressed air is injected through an air pipe nozzle to purge the target titanium plate, and then the target areas can be defined as air injection coverage areas of the air pipe nozzle on the passing path of the target titanium plate, in this embodiment, temperature detection is performed on the inlet position and the outlet position of the rolling mill through infrared temperature measuring equipment to obtain temperature parameters; for the acquired temperature parameters, a corresponding position tag needs to be added, wherein the position tag at least represents the acquisition position of the temperature parameters, for example, in some embodiments, a position tag '1' is specified to indicate that the temperature parameter acquisition position is the front end of the rolling mill, a position tag '2' is specified to indicate that the temperature parameter acquisition position is the rear end of the rolling mill, and when the measured temperature parameter is 800 ℃ in a target area defined from the front end of the rolling mill, namely an inlet position, a tag '1' is added to the target area; it will be appreciated that the temperature parameter reflects the temperature of the target zone, and that the detected temperature parameter reflects the temperature of the apparatus itself, e.g. the rail, etc., when the target titanium plate does not enter the target zone, and that the temperature is low when the target titanium plate moves on the rail towards the rolls of the rolling mill, and that the detected temperature parameter reflects the temperature of the target titanium plate when it enters the target zone, and that the temperature is high, whereby a difference in temperature parameter is created for subsequent determination.
And step S120, judging the temperature parameter according to a preset temperature threshold range, and if the temperature parameter falls into the temperature threshold range, marking the corresponding position label as a target position label.
For step S120, whether the obtained temperature parameter falls within a temperature threshold range is determined according to a preset temperature threshold range, where the temperature threshold range refers to a preset numerical range for determining the temperature parameter, for example, in some embodiments, the obtained temperature parameter is a celsius temperature value collected from a target area through an infrared temperature measurement device, the temperature threshold range is, for example, a celsius temperature value range in a target titanium plate rolling process, when the celsius temperature value of the temperature parameter falls within the preset celsius temperature value range, it is indicated that the target titanium plate meeting the rolling temperature requirement has entered the target area, that is, it may be purged, and at this time, a position tag corresponding to the temperature parameter is marked as a target position tag for the subsequent step to retrieve the tag.
Step S130, obtaining a current rolling pass, and judging whether the current rolling pass and the target position label meet a preset purging trigger condition or not.
For step S130, a current rolling pass needs to be obtained, and it should be noted that the current rolling pass refers to a rolling pass where the target titanium plate is located at the current position, and in step S120, a target position tag is marked, which indicates that the target titanium plate has entered the target area, and it should be understood that two working conditions exist in the same target area for the target titanium plate: in the first working condition state, the target titanium plate is in the beginning stage of the rolling pass of the present round, namely, the target titanium plate enters a target area from the far end of the rolling mill and moves towards the rolling mill, and in the second working condition state, the target titanium plate is in the ending stage of the rolling pass of the present round, namely, the target titanium plate has completed the rolling of the present round and moves outwards from the rolling mill into the target area;
In some embodiments, the preset purging trigger conditions do not limit the current rolling pass, only limit the target position label, namely, no matter how many current rolling passes are, the purging trigger conditions are met as long as the target position label is judged to exist, purging is carried out according to the target position label, and if two working condition states are not distinguished, purging is carried out on the target titanium plate when the target titanium plate enters the rolling mill and leaves the rolling mill;
in this embodiment, the present application further specifically provides a scheme for determining according to a current rolling pass and a target position tag, and specifically, the purge trigger condition includes a first trigger condition and a second trigger condition:
the first purging triggering condition is that the current rolling pass is an odd pass, the target position label is a front end position label, and the acquiring position of the front end position label representing the temperature parameter is the front end of the rolling mill;
the second purging trigger condition is that the current rolling pass is an even pass, the target position label is a rear end position label, and the rear end position label represents that the acquisition position of the temperature parameter is the rear end of the rolling mill;
It can be understood that the front end position tag is a position tag added to the temperature parameter acquired by the front end region, the rear end position tag is a position tag added to the temperature parameter acquired by the rear end region, and in the first trigger condition and the second trigger condition, the parity of the rolling pass is associated with the acquisition position of the position tag;
Specifically, in multi-pass rolling, when a rolling pass is an odd pass, the moving direction of the target titanium plate enters the rolling mill from the front end of the rolling mill, and leaves the rolling mill from the rear end of the rolling mill, if the position label is a front end position label, the target titanium plate is positioned in a target area at the front end of the rolling mill, the rolling mill is not started, a first purging trigger condition is met, if the position label is a rear end position label, the target titanium plate is positioned in a target area at the rear end of the rolling mill, the rolling of the pass is finished, and leaves the rolling mill, and the first purging trigger condition is not met; when the rolling pass is an even pass, the moving direction of the target titanium plate enters the rolling mill from the rear end of the rolling mill, and leaves the rolling mill from the front end of the rolling mill, if the position label is a front end position label, the target titanium plate is positioned in a target area at the front end of the rolling mill, the rolling of the pass is completed and leaves the rolling mill, the second purging trigger condition is not met, if the position label is a rear end position label, the target titanium plate is positioned in a target area at the rear end of the rolling mill, the rolling of the pass is not started, and the second purging trigger condition is met; by setting the first triggering condition and the second triggering condition, working condition states of the target titanium plate in different target areas can be effectively distinguished according to the current rolling pass, whether the target titanium plate enters the rolling mill or leaves the rolling mill at present is judged, and the purging triggering condition is met only when the target titanium plate is located in the target area and enters the rolling mill, namely, the target titanium plate can be precisely purged at the beginning stage of each rolling pass through the judging method, so that the purging round is facilitated to be simplified, the purging efficiency is improved, and meanwhile, the resource waste caused by repeated purging is avoided.
Step S140, if the current rolling pass and the target position tag meet the purging trigger condition at the same time, purging the target area corresponding to the target position tag.
For step S140, the purging operation control needs to be performed according to the determination structure of step S130, if the current rolling pass and the target position tag meet the purging trigger condition at the same time in step S130, this indicates that purging is required, in this embodiment, the present application specifically shows a scheme for purging the target area, as shown in fig. 2, in this scheme, a first purging unit towards the first target area is provided at the front end of the rolling mill, and a second purging unit towards the second target area is provided at the rear end of the rolling mill, and specifically includes the following steps:
Step S210, if the first purging trigger condition is met, controlling the first purging unit to purge the first target area;
Step S220, if the second purging trigger condition is met, controlling the second purging unit to purge the second target area model.
For steps S210 to S220, the method of purging in the embodiment when the first purging trigger condition and the second purging trigger condition are respectively satisfied is further described, specifically, the target area is divided into a first target area at the front end of the rolling mill and a second target area at the rear end of the rolling mill, when the first purging trigger condition is satisfied, it is indicated that the target titanium plate is located in the first target area at the front end of the rolling mill, the rolling of the pass is started without entering the rolling mill, when the second purging trigger condition is satisfied, it is indicated that the target titanium plate is located in the second target area at the rear end of the rolling mill, the rolling of the pass is started without entering the rolling mill, and at this time, the target titanium plate in the second target area is purged by the method, and the method accurately purges the target titanium plate at the beginning of each rolling pass, thereby being favorable to simplifying the number of purges, improving the purge efficiency and simultaneously avoiding the resource waste caused by repeated purges.
In this embodiment, in step S140, that is, in the step of purging the target area corresponding to the target position tag, the method further includes the following steps:
when the target area is purged, if the temperature parameter exceeds the temperature threshold range and the duration is not less than 1S, stopping purging;
for the above steps, it should be understood that the acquisition of the temperature parameter may be periodic or continuous in real time, so as to be able to judge the purging requirement of the target area in time, for example, in this embodiment, the temperature parameter may be acquired in real time; if it is detected that the temperature parameter at a certain time is outside the temperature threshold range while the purge action is still ongoing, it indicates that at least two situations are possible: 1. the temperature defect area exists on the target titanium plate, namely, the temperature of a part of the area exceeds the temperature threshold range, if the defect area is smaller, the purging is not required to be stopped, if the defect area is larger, the purging is required to be stopped when the process defect of the target titanium plate is larger, the purging is required to be stopped when the process defect area is larger, in order to accurately distinguish the two conditions, the delay time 1S is set in the embodiment, the detection of the temperature parameter is still continuous in the purging process, when the temperature parameter is continuously 1S and exceeds the temperature threshold range, the purging action is controlled to stop, because the target titanium plate is kept moving in the target area, if the temperature parameter is continuously 1S and exceeds the temperature threshold range, the target titanium plate is not separated from the target area, or the temperature of the larger area on the target titanium plate does not meet the rolling process requirement, the purging is not performed at this moment, and if the time that the temperature parameter is longer than 1S, the temperature defect of the small area exists on the target titanium plate or the temperature detection is in a tolerable error, the process is detected, the requirement of the purging is effectively recognized, and the purging is not controlled to be continued when the purging action is controlled in time.
In this example, there is also specifically provided an embodiment of the purge, specifically: the target area is purged through water jet, the water pressure of the water jet is not more than 0.5Mpa, for example, in some embodiments, the water jet with the water pressure of 0.3Mpa is sprayed towards the target area to purge the target titanium plate in the target area, the water jet can be provided by a water pipe pipeline which is opened and closed by a solenoid valve, a ball valve and other valves, the water pressure of the water jet can be provided by a pressure pump connected in series with the water pipe pipeline, and the implementation mode belongs to the common prior art, and is not limited in this way, the method is beneficial to further reducing the temperature influence of purging on the target titanium plate in the rolling process, and further improving the rolling quality.
In summary, in the titanium plate rolling purging method provided by the application, temperature detection is performed on the target areas at the front end and the rear end of the rolling mill to obtain temperature parameters, corresponding position labels are added to each temperature parameter, the temperature parameters are judged according to a preset temperature threshold range, if the temperature parameters fall into the temperature threshold range, the corresponding position labels are marked as target position labels, the current rolling pass is obtained and judged, if the current rolling pass and the target position labels simultaneously meet the purging trigger condition, the target areas corresponding to the target position labels are purged, the problem that dust and impurities generated in the rolling process are continuously attached to the surface of a titanium plate, so that irreversible damage is generated on the surface of the titanium plate after multiple passes of rolling is solved, purging quality and purging efficiency in the rolling process are effectively improved, negative influences of purging on rolling temperature are avoided, rolling efficiency and rolling quality are favorably improved, and the titanium plate rolling purging method has the characteristics of controllable cost, ingenious design and strong practicability
In an embodiment, referring to fig. 3, the present application further exemplarily shows a titanium plate low-temperature rolling purging device, which specifically includes a temperature detection module 301, a first judgment module 302, a second judgment module 303, and a purging execution module 304, where specific functions of the modules are as follows:
