Description
Technical field
The utility model relates to the metallurgical automation field, refers in particular to that slag detects the control system under a kind of electromagnetic type that comprises ladle roughing slag detection, control mode and integrated system.
Background technology
In continuous casting production process, the covering slag of ladle can play the effect that prevents molten steel oxidation, keeps big-and-middle Baogang coolant-temperature gage, but the tundish slag blanket blocked uply then can pollute molten steel, accelerate the tundish burn into of anti-the material and reduced slab quality, increased production cost.Popularization along with ladle long nozzle protection casting mode; Mode through perusal or infrared photography can't stop the ladle slag to be leaked in the middle bag timely; Can only be through watching tundish to turn over slag or detect the following quantity of slag of this dual mode control ladle of ladle weight, but all there is the drawback that can not solve in this dual mode: watch Zhong Bao to turn over slag and will make the thickening of tundish slag blanket, thereby bring slag inclusion; Reduce steel quality, reduce tundish service life; Be not sure of whether descend slag more and detect ladle weight, not only influence steel quality, also can reduce the recovery rate of molten steel, improve production cost.Therefore, effectively the ladle roughing slag detection technique to improve slab quality, improve the molten steel recovery rate, extremely important meaning has reduced production costs.
There are several kinds of multi-form ladle roughing slag detection techniques at present, for example: based on the following slag detection technique of solenoid sensor, based on slag detection technique under the oscillatory type of acceleration transducer, based on slag detection technique under the outside electromagnetism in the mouth of a river etc.Following slag detection based on the solenoid sensor is to utilize the principle of electromagnetic induction to detect the percentage of dregginess in the molten steel.Coil is installed between steel ladle sliding water gap and the ladle base, and molten steel passes through from hub of a spool, thereby directly measures the content of slag in the molten steel.Because used the principle of electromagnetic induction, make this time slag detection system system features in convenient, each use as long as the plug quick plug just can, need not unload long nozzle; Be difficult for affected by environmently, accuracy is high; Antijamming capability is strong.But because solenoid is mounted in the ladle; Therefore each ladle all must be equipped with a sensor, and cost is higher, simultaneously; Sensor is followed ladle and is advanced the refining furnace refining; Cause sensor to receive high-temperature baking so life-span shorter, under ladle does not roll off the production line the situation that just can not get safeguarding, use to can not get continuously.The principle that slag is surveyed in vibration is to be installed on the ladle manipulator through degree of will speed up sensor, and the detecting operation vibration of bar changes, thereby whether judges ladle roughing slag.Because sensor need not be installed on the ladle, therefore this survey slag mode is easy for installation, the length of comparing with coil type service life.But because the environment that uses is comparatively abominable; It is higher much larger than slag signal so rate of false alarm to exist many disturbing factors (like noise, last ladle, slide gate nozzle motion, beam rapid change, gas suction, boundary condition, the tectal thickness of middle diversity and viscosity) to change the interfering signal that causes, reliability is relatively poor.Based on slag detection technique under the electromagnetism of long nozzle outside is to utilize solenoid to generate an electromagnetic field, and molten steel in the long nozzle and slag will produce an induced-current through this electromagnetic field, thereby whether judges long slag down.The method and apparatus that patent document JP54119336A and patent document EP1486272A1 are mentioned utilizes this principle to realize.
Patent document JP54119336A has utilized the differing heights position probing of two groups of solenoids at long nozzle, and provide one independently horizontal drive mechanism coil can be moved forward and backward be used to avoid long-time high-temperature baking.Yet; Owing to ladle long nozzle along with steel ladle sliding water gap moves; Independently horizontal drive mechanism will cause C type framework to locate, and since two groups of coils not on same horizontal plane, the structure of C type framework will be very huge; Under ladle and the situation of tundish distance, can't use than weak point.Patent document EP1486272A1 has utilized at least one to send coil and has generated an electromagnetic field with at least one receiving coil; And will send coil, receiving coil, install in two branches of forked bobbin; Make and send coil, receiving coil, ladle long nozzle on same straight line; Ladle long nozzle is between two coils; Simultaneously, forked bobbin is fixed on the front end sleeve pipe of ladle manipulator through shaft-like coupling part, thereby big change does not take place the relative position that guarantees sensor and long nozzle.Yet the ladle manipulator is when changing ladle long nozzle, and molten steel has very big probability to leak out, can not move because forked bobbin is fixed on the manipulator, so molten steel will drench the damage that causes forked bobbin on the forked coil; In addition, because send coil and the vertical helically coiling of receiving coil, must be on same straight line so send coil, receiving coil and long nozzle, this will cause safeguarding the inconvenience of installation.In above two patent documents, though the cooling of all sensor being carried out, because the tundish area is bigger; Radiation temperature on every side is also very high, and the cable of introducing coil can not get protection, particularly patent document JP54119336A; When C type framework moves forward and backward; Cause cable sagging possibly, cable directly immerses in the tundish molten steel, causes cable to burn.
In continuous casting production process, generally use the ladle long nozzle manipulator.The major function of ladle long nozzle manipulator is to be installed on the steel ladle sliding water gap long nozzle and the replacing long nozzle, the effect that prevent molten steel oxidation to play, keeps big-and-middle Baogang coolant-temperature gage.In order to improve slab quality, improve the molten steel recovery rate, to reduce production costs; Most of continuous casting lines have adopted the ladle roughing slag detection technique, and electromagnetism suspension type ladle roughing slag detection technique is used more extensive, and this technology needs sensor is installed on the ladle long nozzle manipulator; When needs detect in the ladle nozzle slag content; Transmission mechanism is delivered to sensor near the ladle long nozzle, and in the time need not detecting, transmission mechanism is entrained back into sensor away from the ladle long nozzle place.At present traditional ladle long nozzle manipulator effect is single, and on telescoping tube, does not reserve the position of sensor installation transmission device, and structure is too fat to move, operating difficulties.
Existing electromagnetic type is surveyed the slag sensor and is generally formed by sending coil and receiving coil.The loop coil sensor is to be circularized by two groups of line helically coilings to be stacked, and the outside is by the stainless steel casing encapsulation and be installed in ladle bottom, and when detecting, molten steel and slag pass through from toroidal circle centre position, reach the purpose of detection.Because this kind sensor is installed in ladle bottom, each replacing need be with the ladle lining damage layer, so the difficulty of replacing, use cost is higher.The sensor that detects in the outside, the mouth of a river is also formed by sending receiving coil, and patent document JP54119336A and patent document EP1486272A1 once described this type sensor.In patent document JP54119336A; A kind of sensor construction is provided; This structure has used two groups of emission receiving coils to lay respectively in two branches of sensor; And two groups of coils are positioned on the different horizontal face, and move forward and backward through drive apparatus independently and to be used to shorten the time that sensor stops in the high-temperature region, and this structure can receive the molten steel information in the long nozzle of different cross section.But,, cause using very difficulty because two groups of coils do not cause structure very huge on same horizontal plane; And owing to moving around of sensor, at tundish burn easily by sagging causing for cable.In patent document EP1486272A1; Other a kind of sensor construction is provided; This structure is that transmission and receiving coil are respectively charged in two branches of shell; When detecting, need to send coil, receiving coil, long nozzle and be in a straight line, make long nozzle between transmission, receiving coil, and this sensor is to be fixed on the manipulator front end sleeve.This sensor construction is simple, use restricted little, but because coil adopts spiral assembling coiling, must let two coils and long nozzle be on the same straight line, this will cause installation requirement higher, if mechanically deform takes place, adjustment is difficult; And sensor is to be fixed on machinery, accepts high-temperature baking for a long time, and the life-span is also shorter relatively.
Summary of the invention
