Closed-loop control system for taper of crystallizer

Abstract

The invention provides a closed-loop control system for the taper of a crystallizer. The closed-loop control system comprises a crystallizer narrow side copper plate and a supporting plate. The crystallizer narrow side copper plate and copper plate back plates are fastened together through screws, and the copper plate back plates are wedged together by the supporting plate through two toothed embedded blocks. The upper end of the supporting plate is connected with an upper lead screw mechanism, and the lower end of the supporting plate is connected with a lower lead screw mechanism. The upper lead screw mechanism and the lower lead screw mechanism are hinged to the supporting plate through pin shafts. The upper lead screw mechanism is connected with an upper worm speed reducer, and the lower lead screw mechanism is connected with a lower worm speed reducer. An upper tilt angle sensor is arranged on the upper portion of the front end of the supporting plate, and a lower tilt angle sensor is arranged on the lower portion of the front end of the supporting plate. According to the system, the taper of the narrow side of the crystallizer can be reflected accurately and directly, the closed-loop control system is composed of a controller device and a servo motor or a hydraulic cylinder through taper signals detected by the tilt angle sensors, the taper of the crystallizer can be adjusted online in real time and displayed in real time, and the most visual reference is given to producers.

Description

technical field [0001] The invention belongs to the field of metallurgical continuous casting equipment, in particular to a mold taper closed-loop control system. Background technique [0002] In modern iron and steel production enterprises, continuous casting is one of the very important links between the preceding and the following. The crystallizer equipment is an extremely important key equipment in this link. Since different steel types have different shrinkage characteristics when they solidify and shrink, the mold taper plays a key role in the safety of continuous casting production and the stability of slab quality. Therefore, it is concluded by combining theory and practice: Stability It is very important that the crystallizer taper is stable in production. So far, the continuous stability of the mold taper has been a difficult technical problem in the continuous casting production process. At present, the adjustment method of crystallizer taper can be divided in...
