A sector-type tension leveling device and tension leveling equipment

Abstract

The invention provides a sector-type tension-leveling device and tension-leveling equipment. The sector-type tension-leveling device consists of a frame (1) and five pairs of work rolls arranged sequentially along the casting direction. The five pairs of work rolls The rollers are arranged in the frame (1). There are five pairs of work rolls in one frame of the sector-type tension leveling device, that is, in the tension leveling equipment, the tension leveling device composed of five pairs of work rolls and a single frame replaces the existing one pair of work rolls and a single machine The tension-leveling device composed of racks can distribute the light reduction achieved by one pair of work rolls in the existing tension-leveler to five pairs of work rolls. In this way, the amount of light reduction shared by each pair of rollers in the sector-type tension leveling device is greatly reduced and more uniform, which not only improves the efficiency of light reduction, but also improves the effect of light reduction.

Description

technical field [0001] The invention relates to the technical field of continuous casting equipment, in particular to a sector-type tension-leveling device, and a tension-leveling equipment including the sector-type tension-levelling device. Background technique [0002] The light reduction of square billets is a major advanced technology to improve the internal quality of billets, especially to solve the central segregation and porosity of high carbon steel has a significant effect. The precise control of the reduction position and reduction amount is the key technology to realize the metallurgical effect of dynamic soft reduction. [0003] The continuous casting of carbon steel, low alloy steel, special steel and other steels is a technology developed 20 years after the straight arc continuous casting machine was put into production. Although compared with die casting, continuous casting has advantages in terms of product output and quality, but in the current era of purs...

AI Technical Summary

Problems solved by technology

[0009] In order to solve the problem that the distance between the front and rear rollers of the traditional light reduction equipment is relatively large, the present invention provides a sector-type tension-leveling device and tension-leveling equipment. A frame of the sector-type tension-leveling device contains five pairs of Work rolls, that is, in the tension leveling equipment, the tension leveling device composed of five pairs of work rolls and a single frame replaces the existing tension leveling device composed of a pair of work rolls and a single frame, so that the existing tension leveler The light reduction achieved by one pair of work rolls is spread over five pairs of work rolls
