Constant-rate rolling mill outlet device

Abstract

The invention relates to the technology of a strip rolling production line, in particular to an outlet device of a rolling mill. A rolling mill exit device that can realize constant-speed rolling, including a tension roll set and a looper, the output of the rolling mill is connected to the tension roll set, the tension roll set is connected to the looper, the looper is connected to another tension roll set, and the other tension roll set Connected to the crimping machine; the looper includes two sets of upper and lower looper rollers, the upper roller is assembled on the bracket and can move up and down, the lower roller is fixed, and the plate and strip pass between the upper and lower rollers; the tension roller includes One moving roller and one fixed roller, the moving roller is installed on the outer ring of the rotatable disc, the fixed roller is installed at the center of the disc, and the circumference of the outer ring of the disc is toothed, and the tooth shape is in phase with the gear driven by the motor Engaging, turning the disc can make the moving roller turn to the working position and the belt threading position. The invention enables the rolling mill to keep rolling at a higher speed at a constant speed, thereby increasing productivity, improving the thickness of the head and tail of the strip steel and the quality of the plate shape, and increasing the metal yield.

Description

technical field [0001] The invention relates to the technology of a strip rolling production line, in particular to an outlet device of a rolling mill. Background technique [0002] Strip rolling has gradually developed from the earliest sheet rolling to coil rolling and finally to continuous rolling. The emergence of continuous rolling mills has realized endless rolling, eliminating the need for low-speed, unstable strip threading and tailing processes, not only greatly increasing the average rolling speed, improving the productivity of the rolling process, but also reducing the thickness of the head and tail and the thickness of the plate. The over-tolerance length of the shape improves the product quality and yield. [0003] Continuous rolling can be divided into three forms. The first is a single full continuous rolling mill, which is to add welding machines, loopers and other equipment in front of the conventional cold rolling mill to make cold-rolled strips uninterrup...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a rolling mill outlet device that can realize constant-speed rolling. Due to the defect of strip head-to-tail speed up and down caused by the bite of the coiler, the rolling mill can maintain constant rolling at a higher speed by adding a tension roll group and a looper that are easy to wear the strip after the rolling mill, so as to improve productivity , to improve strip thickness and shape quality
