Fan-shaped section type withdrawal and straightening device and withdrawal and straightening equipment

Abstract

The invention provides a fan-shaped section type withdrawal and straightening device and a set of withdrawal and straightening equipment. The fan-shaped section type withdrawal and straightening device is composed of a machine frame (1) and five pairs of working rollers which are sequentially arranged in the casting direction. The five pairs of working rollers are arranged in the machine frame (1). The five pairs of working rollers are arranged in the machine frame of the fan-shaped section type withdrawal and straightening device; in other words, an existing withdrawal and straightening device composed of one pair of working rollers and one machine frame is replaced with the withdrawal and straightening device composed of the five pairs of working rollers and the machine frame in the withdrawal and straightening equipment; and therefore, the slight pressing amount of the pair of working rollers in the existing withdrawal and straightening machine is dispersed to the five pairs of working rollers. Therefore, the slight pressing amount borne by each pair of rollers in the fan-shaped section type withdrawal and straightening device is greatly decreased and is more uniform, the slight pressing efficiency is improved, and the slight pressing effect is improved.

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
