Abstract

The invention provides a method for improving position control accuracy for a roll change trolley for a working roll. The method comprises the following steps: carrying out position point division onan action range of the roll change trolley for the working roll; subdividing the position points; selecting three key positions E1, E6 and E11, and installing high-accuracy proximity switches; participating in correction for position measurement for a coder through the accurate proximity switches; and finally improving the position control accuracy for the roll change trolley for the working roll.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a method for improving the position control accuracy of a work roll changing trolley. Background technique [0002] The work rolls used in the steel rolling process are transported by the work roll changing trolley to the designated position for replacement. [0003] The work roll changing trolley is the key equipment in the roll changing system, and the accuracy of its position control directly affects the stability of the roll changing system. Poor position control accuracy will lead to a series of serious consequences, which will cause damage to the mechanical equipment of the roll changing system. Serious consequences of cable cut-off of the roll trolley; all along, how to improve the position control accuracy of the work roll change roll roll change trolley is an important and difficult point, and its position control accuracy will directly affect the stability of the...
