Edging mill position control method

Abstract

The invention provides an edging mill position control method, and belongs to the field of edging mill position control. The edging mill position control method comprises the following steps of determining positioning precision and rolling control precision of an edging mill, wherein the rolling control precision can meet the requirements of the production process, and the absolute value of the positioning precision is smaller than that of the rolling control precision; finishing positioning with the positioning precision in the positioning period of the edging mill when the actual position ofthe edging mill runs within a positioning precision range; and interrupting rolling with the rolling control precision in the rolling period of the edging mill when the position of the edging mill exceeds the rolling control precision. According to the method, the positioning precision of the edging mill is controlled in a multi-stage precision control mode, so that respective control programs ofthe positioning precision and the rolling control precision are separately interlocked; the positioning precision of the edging mill is improved; the process control requirement of the edging mill ismet; and the working stability of the edging mill is guaranteed.

Description

technical field [0001] The invention relates to the field of position control of an edger, in particular to a method for controlling the position of an edger. Background technique [0002] The positioning accuracy of universal E1 edge mill is ±1mm. Within the range of positioning accuracy, the equipment does not adjust it, and its position protection value is ±1mm at the same time. When the position exceeds ±1mm, the system enters the interruption mode. [0003] Since the edger is a movable device, the frame of the edger must be locked during rolling so that the edger can pass through the steel normally. After the edger equipment moves into place, there is a process of waiting for the edger frame to be locked. However, according to the characteristics of hydraulic equipment: the hydraulic cylinder inevitably has internal leakage; the compressed hydraulic oil has a small energy release when the main oil circuit is cut off. Therefore, after the frame is locked, it often happ...
