Abstract
The utility model relates to a hot strip mill finishing mill loop hoisting dynamic location control device, which comprises an angle sensor, an oil pressure sensor, a machine frame speed encoder, a roll gap sensor, a thickness controller, a finishing mill group speed controller, a loop controller and an actuating mechanism, and is characterized in that outlet signals of the roll gap sensor are connected with the thickness controller, the output signals of an arc length real time loop amount calculating element which is contained in the thickness controller, the machine frame speed encoder and the loop controller are respectively connected with the finishing mill group speed controller, the output signals of the finishing mill group speed controller, the angle sensor and the oil pressure sensor are respectively connected with the loop controller, the output signals of the loop controller is connected with a loop hydraulic actuating mechanism. Because the hot strip mill finishing mill loop hoisting dynamic location control device controls a loop hoisting height angle of a falling loop according to the change of loop amount, which is produced by unbalanced real time second flow rate of upstream and downstream machine frames, the compact to strip steel is effectively reduced during the process of threading strips for a loop, and a head portion of the strip steel is prevented from being pulled narrow.
Description
Technical field
The utility model belongs to control device, is that the hot-rolling finishing mill kink plays cover dynamic position control device specifically.
Background technology
In the hot continuous rolling process, the cover time of rising of wishing looper gear usually is short as far as possible, thereby require kink to play cover at a high speed, speed is enough little when requiring kink to contact with the strip again simultaneously, to avoid contact zones steel moment that the band steel is impacted, drawing down band steel toe portion causes " constriction ", influence band steel toe portion's dimensional accuracy and end product quality.Kink is stung the steel cover of moment at present, adopts dual mode usually, and a kind of is to have fixed the control of cover angle position, and another kind is the direct tension force control of no Position Control.In this dual mode, the former must cause the unusual fluctuations of width and thickness because fixedly the target setting angle is different to the influence degree of the band steel drawing down of unlike material and temperature; The latter because dynamic velocity drop recovery time is short executing agency's response time long, have little time feedback compensation, both all inevitably cause and are with the drawing down of steel at head.Therefore design a kind of can according to the uneven cover quantitative changeization that produces of upstream and downstream frame real time second flow control conform to a conventional pattern play the cover elevation angle, to play cover dynamic position control device with the hot-rolling finishing mill kink of avoiding drawing down band steel toe portion very necessary thereby reduce in the kink crossing process impact to the band steel.
Summary of the invention
The purpose of this utility model provides a kind of hot-rolling finishing mill kink and plays cover dynamic position control device, to avoid drawing down band steel toe portion in the kink crossing process.
For achieving the above object, the utility model adopts following technical scheme: the hot-rolling finishing mill kink plays cover dynamic position control device, comprise angular transducer, oil pressure sensor, speed encoder, downstream frame speed encoder, the roll gap sensor, gage controller, the mm finishing mill unit speed control, looper controller and kink hydraulic actuating mechanism, it is characterized in that angular transducer is arranged on the kink axle, oil pressure sensor is arranged on the oil circuit porch of kink oil cylinder, speed encoder is arranged on the roll drive motors tail end of frame, downstream frame speed encoder is arranged on the roll drive motors tail end of downstream frame, the roll gap sensor is arranged on the backing roll upper end of frame, the roll gap signal of sensor is connected with gage controller, the output signal of gage controller is connected with the mm finishing mill unit speed control, the output signal of speed encoder and downstream frame speed encoder is connected with the mm finishing mill unit speed control respectively, the output signal of mm finishing mill unit speed control is connected with looper controller, the output signal of angular transducer and oil pressure sensor is connected with looper controller respectively, contain in the looper controller arc length in real time the output signal of cover amount computing unit be connected with the mm finishing mill unit speed control, the output signal of looper controller is connected with the kink hydraulic actuating mechanism.
During the utility model work, the signal that gage controller is sent here according to the roll gap sensor in conjunction with the variation of thickness regulated value, calculates through internal processes, gives the mm finishing mill unit speed control with control signal.The mm finishing mill unit speed control is according to containing the arc length signal sent here of cover amount computing unit in real time in speed encoder, downstream frame speed encoder, gage controller and the looper controller, reset definite value in conjunction with the kink plate, calculate through internal processes, give looper controller control signal.The signal that looper controller is sent here according to mm finishing mill unit speed control, angular transducer and oil pressure sensor in conjunction with the tension force setting value, calculates through internal processes, gives the kink hydraulic actuating mechanism with control signal.Because can controlling rising of conforming to a conventional pattern according to the uneven cover quantitative changeization that produces of upstream and downstream frame real time second flow, the utility model overlaps elevation angle, therefore all can keep between the frame of upstream and downstream metal mass flow constant under the different rolling conditions, effectively reduced in the kink crossing process being with the impact of steel, avoided drawing down band steel toe portion
