Automatic grinding method and medium for visual continuous furnace roll

Abstract

The present invention provides an automatic grinding method and medium for visual continuous unloading furnace rollers, wherein the method includes a starting step, a T1 timing step, and a T2 timing step; the starting step: selecting a grinding furnace section and starting the grinding equipment and the grinding system ;T1 timing step: start grinding, activate timer T1 and make a judgment. If T1 does not reach the preset time condition, activate the grinding equipment and grinding system, and start the furnace roll grinding. If T1 reaches the preset time Condition, stop grinding and activate timer T2; T2 timing step: after the timer T2 is activated, make a judgment, if T2 does not reach the preset time condition, keep the furnace roll grinding stop, if T2 reaches the preset time condition , then increment the value of counter C1 by 1.

Description

technical field [0001] The invention relates to the field of metallurgical automation, in particular to an automatic grinding method and a medium for a visualized continuous furnace roll. Background technique [0002] The heating furnace is the key equipment of the continuous withdrawal unit. The tension control method is currently used for the control of the furnace roller motors in the furnace section, that is, ASR (speed control loop) + ATR (tension control loop) in the basic automation PLC. During the process, the control amount of the furnace rolls in each furnace section is the same (see figure 1 ). When the nodulation of the furnace rolls is serious, a large range of needle-like pitting will appear on the surface of the strip, which does not meet the requirements for high-quality strips, and the time and cost of replacing the furnace rolls in the continuous withdrawal unit is huge, so measures need to be taken to prevent the nodules. Mitigate the effects of pitting ...
