Abstract
The invention relates to the field of cold steel rolling equipment, in particular to a rolling mill. The rolling mill has the capacity of producing wide strip steel more efficiently. The rolling mill comprises paired working rollers, paired intermediate rollers and paired supporting rollers. A steel rolling inlet and a steel rolling outlet are formed between the paired working rollers, the paired working rollers are arranged between the paired intermediate rollers, the working rollers and the intermediate rollers are all arranged between the paired supporting rollers and the supporting rollers, the intermediate rollers and the working rollers are located in a vertical straight line. The working rollers and the intermediate rollers are all arranged between the paired supporting rollers, and the manufacturing efficiency of the equipment during steel plate rolling can be effectively improved. In actual use, a steel plate to be rolled is fed through the steel rolling inlet, under the action of the upper working roller and the lower working roller, rolling can be conducted quickly and manufacturing can be realized. The rolling mill can be applied to strip steel products such as the wide strip steel.
Description
Technical field
The present invention relates to cold-rolled steel apparatus field, especially a kind of milling train.
Background technology
An important use of milling train is that steel plate is made into thinner steel plate sheet material, so that the use of some production fields.Traditional milling train consists of a backing roll, an intermediate calender rolls and a working roll, and due to the restriction of structure, the steel rolling effect of conventional mill is limited, and the width of the external force that can provide during steel rolling and steel rolling is also limited.Along with the development of present Production requirement, need to use wide flat steel more substantial and that width is wider, use traditional milling equipment to be difficult to provide corresponding product.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of more milling train of High-efficient Production wide flat steel ability that has.
The technical solution adopted for the present invention to solve the technical problems is: milling train, comprise paired working roll, paired intermediate calender rolls and paired backing roll, between described paired working roll, form steel rolling import and steel rolling outlet, paired working roll is arranged between paired intermediate calender rolls, described working roll and intermediate calender rolls are all arranged between paired backing roll, and backing roll, intermediate calender rolls and working roll are on a vertical straight line.
Further, the diameter range of described working roll is 310 millimeters of Φ 290～Φ, and the length range of working roll is 1000～1200 millimeters.
Further, the diameter range of intermediate calender rolls is 400 millimeters of Φ 370～Φ, and the length range of intermediate calender rolls is 900～1150 millimeters.
Further, the diameter range of backing roll is 900 millimeters of Φ 850～Φ, and the length range of backing roll is 900～1080 millimeters.
The invention has the beneficial effects as follows: by being arranged to right working roll, paired intermediate calender rolls and paired backing roll, and steel rolling import and steel rolling outlet will be formed between described paired working roll, paired working roll is arranged between paired intermediate calender rolls, described working roll and intermediate calender rolls are all arranged between paired backing roll, the preparation efficiency in the time of can effectively improving equipment rolled plate.When reality is used, will treat that rolled steel plate sends into from steel rolling import, under upper working rolls and lower working rolls effect, can be rolled fast and realize preparation.Because upper working rolls and lower working rolls has intermediate calender rolls and backing roll separately, support, therefore enter plate speed in the time of can improving rolling, produce fast and effectively band steel.The present invention can be take in the belt steel product that wide flat steel is representative for producing fast.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
In figure, be labeled as: backing roll 1, intermediate calender rolls 2, working roll 3, steel rolling import 31, steel rolling outlet 32.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Milling train as shown in Figure 1, comprise paired working roll 3, paired intermediate calender rolls 2 and paired backing roll 1, between described paired working roll 3, form steel rolling import 31 and steel rolling outlet 32, paired working roll 3 is arranged between paired intermediate calender rolls 2, described working roll 3 and intermediate calender rolls 2 are all arranged between paired backing roll 1, and backing roll 1, intermediate calender rolls 2 and working roll 3 are on a vertical straight line.
When reality is used, that produces first on demand reserves the spacing between paired working roll 3 with steel standard, sets steel rolling import 31 and steel rolling outlet 32.Paired working roll 3 is being arranged between paired intermediate calender rolls 2, and when working roll 3 and intermediate calender rolls 2 are all arranged between paired backing roll 1, need to guarantee that backing roll 1, intermediate calender rolls 2 and working roll 3 are on a vertical straight line, such arrangement is simple and force transmission effect good.
For meeting the need of production of some wide flat steel, can under the prerequisite of said structure, the parameter of working roll 3 be adjusted, concrete: the diameter range of working roll 3 is 310 millimeters of Φ 290～Φ, and the length range of working roll 3 is 1000～1200 millimeters.Owing to having adopted paired working roll 3, arrange, can under this spline structure prerequisite, by the diameter range of working roll 3, be directly 310 millimeters of Φ 290～Φ, improving is like this in order to make effect of rolling better, and the length range of working roll 3 is designed to 1000～1200 millimeters, in order directly to produce the wide flat steel that width is larger, according to practical data, band steel that can production bandwidth 1010mm, produces Ultra-thin to the Thin Strip Steel of 0.18mm.
Design based on same, in order further to improve production capacity of the present invention, can have following scheme selective: adjust intermediate calender rolls 2 sizes, the diameter range of intermediate calender rolls 2 is adjusted to 400 millimeters of Φ 370～Φ, and the length range of intermediate calender rolls 2 is 900～1150 millimeters.The length of the diameter dimension of increase intermediate calender rolls 2 and increase intermediate calender rolls 2 can allow working roll 3 obtain better power transmission.Same, also can further improve the structural parameters of backing roll 1: the diameter range of backing roll 1 is 900 millimeters of Φ 850～Φ, and the length range of backing roll (1) is 900～1080 millimeters.Also can allow working roll 3 obtain better power transmission.Above-mentioned size increases, all just can obtain corresponding effect of increasing production under structural configuration prerequisite of the present invention, specifically, because the backing roll 1, intermediate calender rolls 2, the working roll 3 that arrange in pairs can clamp together and treat strip rolling up and down, can be independent of surrounding devices and realize the function that increases production capacity.
