A close-packed double-roller continuous tension leveling device and tension leveling equipment

Abstract

The invention provides a densely arranged dual-roll continuous withdrawal and straightening device and withdrawal and straightening equipment. The densely arranged dual-roll continuous withdrawal and straightening device is composed of a rack (1) and two pairs of working rolls sequentially arranged in the casting direction and located inside the rack (1). The rack (1) is provided with a hydraulic cylinder (7) used for driving the two pairs of working rolls. The rack of the densely arranged dual-roll continuous withdrawal and straightening device internally comprises the two pairs of working rolls, namely the withdrawal and straightening device composed of the two pairs of working rolls and one rack in the withdrawal and straightening equipment replaces an existing withdrawal and straightening device composed of a pair of working rolls and a rack, so that the soft press amount achieved by one pair of working rolls in an existing withdrawal and straightening machine is dispersed to the two pairs of working rolls. In this way, the soft press amount borne by each pair of rolls in the densely arranged dual-roll continuous withdrawal and straightening device is greatly reduced and more uniform, so that the soft press efficiency is improved, and the soft press effect is also improved.

Description

technical field [0001] The invention relates to the technical field of continuous casting equipment, in particular to a close-packed double-roller continuous tension-levelling device, or a tension-levelling equipment containing the close-packed double-roller continuous 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 prod...

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 close-packed double-roller continuous tension leveling device and tension-levelling equipment. It contains two pairs of work rolls, that is, the tension leveling device composed of two pairs of work rolls and a single frame in the tension leveling equipment replaces the existing tension leveling device composed of a pair of work rolls and a single frame, so that the existing The light reduction achieved by one pair of work rolls in a tension leveler is distributed over two pairs of work rolls
