Strip head treatment device for skin pass unit and method of use thereof

Abstract

The invention relates to a band steel heat treatment device for a temper mill. The device is arranged on an inlet side of a steel coil channel of the temper mill, and comprises a compression roller, a pair of carrier rollers, an uncoiler, a band steel molding device, a hydraulic shearing device and a waste box, which are sequentially arranged along the direction vertical to the steel coil channel, wherein the pair of carrier rollers is symmetrically arranged along the steel coil channel; the band steel molding device comprises a band steel pinch roll; the compression roller, the pair of carrier rollers and the band steel pinch roll all can rotate positively and reversely; and an up uncoiling manner is adopted as the steel coil uncoiling manner. The invention further relates to an application method of the band steel heat treatment device. The band steel heat treatment device is arranged on the inlet side of the steel coil channel of the temper mill, so that technological arrangement is simple; a channel does not need to be additionally formed; the civil engineering and equipment investment are effectively saved; the band steel heat treatment device is adjacent to the temper mill, so that a plurality of middle procedures are reduced; the operation of an operator is convenient; the labor amount of the operator is effectively reduced; the band steel heat treatment efficiency is relatively high; the transportation cost and the time cost are reduced; and the production benefits are improved.

Description

technical field [0001] The invention relates to the technical field of cold-rolling and leveling of steel strips, in particular to a strip head processing device for a skin-passing unit and a method for using the same, which can be used for various cold-rolling, leveling and processing line units. Background technique [0002] At present, in the production process of the skin-passing unit, the auxiliary time occupies more than half of the production time. Shortening the auxiliary time is the most effective way to increase the production capacity of the unit. Auxiliary operations such as uncoiling, threading, and online processing of out-of-tolerance parts of the strip-passing unit are key The most time-consuming place in production. For the tempering unit after bell annealing, the strip head has problems such as poor plate shape, bonding, and edge folds during transportation, which cause great trouble to the uncoiling and threading of the steel coil, and sometimes it is nece...
