Electric moving type dance roll tension adjusting equipment for cold-rolling strip steel

Abstract

The invention discloses electric moving type dance roll tension adjusting equipment for cold-rolling strip steel. The electric moving type dance roll tension adjusting equipment comprises a rack, chain wheels, a chain, a dance roll, a turning roll and a tension detecting device. The chain wheels are symmetrically arranged on the two sides of the rack, and one chain wheel is driven by a forward and reverse rotating motor which is connected with the corresponding chain wheel through a speed reduction driving device. The turning roll is arranged above one chain wheel, and the turning roll is connected to the rack through a supporting column. The chain wheels on the two sides of the rack are connected through the chain, and the dance roll is arranged between the two chain wheels. The dance roll is connected with the chain through a mounting seat, and the dance roll is connected with the rack through a moving seat and can move along a rail on the rack. The cold-rolling strip steel is output by the turning roll via the dance roll, and the tension detecting device is arranged on the turning roll and is used for detecting the tension of the cold-rolling strip steel. The electric moving type dance roll tension adjusting equipment for the cold-rolling strip steel is simple in structure and convenient to operate, solves the problem that the tension of the strip steel in a furnace can not be controlled or compensated when the temperature rises or drops, and improves production quality and production efficiency.

Description

technical field [0001] The invention relates to the technical field of tension adjustment of cold-rolled strip steel, in particular to an electric movable dancer roller tension adjustment device for cold-rolled strip steel. Background technique [0002] In the large-scale high-speed continuous strip steel processing line, the tension control requirements for the strip steel are very strict, especially the stable control of the strip steel tension in the furnace is required, because the steel strip operates under high temperature conditions in the annealing furnace, and the plasticity of the steel strip is obvious Increase, which leads to the shrinkage of the cross-sectional area of ​​the steel strip and the narrowing of the width. Practical operating experience shows that under a fixed tension condition, the narrowing value of the steel strip in the furnace increases with the increase of the furnace temperature. In order to avoid the excessive shrinkage of the cross-section...
