Method for solving difficulty of looping tail at steel rolling production-line

Abstract

A method for preventing the loops from not containing the steel tail features that the load head signal of down stream rolling mill is used as the loop lifting command, the load tail signal of upstream rolling mill is used as the loop lowering command, and the load signal of the first rolling mill is directly used as the control signal of the loop lifters for the next three rolling mills.

Description

technical field [0001] The invention relates to a method for controlling loopers in a steel rolling production line, belonging to the technical field of metallurgy. Background technique [0002] Modern small-scale hot rolling production mostly uses vertical loopers, the frame of which is welded, and the looper rolls are driven by cylinders. The cylinder drives the rotating shaft to make the looper roller installed on the looper arm swing up and down, so that the rolled piece forms a looper. The cylinder is installed above the rolling line on the transmission side for easy maintenance and adjustment. The looper inlet and outlet are equipped with upper and lower guide rollers. There are two separate roller tables in the middle, which play the role of transporting the rolled pieces. During the whole rolling process, the rolled piece is bitten by the second finish rolling mill and removed from the sleeve until the tail of the rolled piece falls out of the last finish rolling ...

Problems solved by technology

Usually such a method is to use the corresponding delay program to control a certain looper to fall in advance, but this method requires the design of a relatively complex logic control program
