Steel billet reciprocating motion control method and system

Abstract

The invention relates to a steel billet reciprocating motion control method and system, and belongs to the technical field of metallurgy automation control methods and systems. According to the technical scheme, the method comprises the following steps of: coordinating a conveying roller way, and calibrating starting point and ending point position coordinates of forward and reverse movement and the position of a laser positioning detection point; the one-way motion distance, the motion speed, the motion speed slope curve parameter and the reversing intermittent time are set by the L2 system and the L1 system; and after the motion control process is started, the L1 system reads parameters and then performs motion control of repeated motion, the steel billet moves back and forth on the output roller way in a reciprocating manner, and after N cycles, when it is detected that the motion starting condition is not met, the motion is ended. The device has the beneficial effects that the reciprocating motion of the steel billet on the continuous casting output roller way is automatically controlled, the device has an automatic calibration function of a one-way motion end point position, accumulated errors can be corrected in time, slipping of the steel billet and the roller way can be researched and judged in time, the labor intensity of personnel is relieved, the fault rate of roller way control is reduced, and the production efficiency is improved. And efficient and stable operation of production is ensured.

Description

technical field [0001] The invention relates to a billet reciprocating motion control method and system, and belongs to the technical field of metallurgical automation control methods and systems. Background technique [0002] When the continuous casting machine is casting, the slab passes through the cutting area and the deburring roller table area successively after being pulled out from the tail of the casting machine, and then enters the output roller table area for on-line and off-line operations. The slab in this area needs to move back and forth regularly on the roller table during the waiting period of the on-line and off-line operations, so as to achieve the purpose of uniform cooling of the slab and uniform heating of the roller table. After the billet passes through the output roller table, the target billet is transported to the steel loading roller table of the heating furnace by the traversing trolley. Therefore, the output roller table, as an important link b...

Problems solved by technology

The disadvantage of this method is that the automation level of the control method is too low, and the switch direction needs to be manually switched back and forth. The control effect and stability directly depend on the operator's experience and business level. Compared with automatic control, manual control is easily affected by the operator's emotions. And the limitation of technical level, and once the manual control is negligent, it will cause billets to stack or collide, causing accidents and affecting production
