On-line red steel elbow straightener

Abstract

The invention relates to an on-line red steel elbow straightener which comprises a stander (1) and an upper straightening roller group and a lower straightening roller group which are arranged on the stander (1), wherein each of the upper straightening roller group and the lower straightening roller group consists of a plurality of straightening rollers (7); the central lines of the straightening rollers (7) of the upper straightening roller group are parallel to one another and positioned on the same horizontal line, and the central lines of the straightening rollers (7) of the lower straightening roller group are parallel to one another and positioned on the same horizontal line; and the straightening rollers (7) of the upper straightening roller group and the straightening rollers (7) of the lower straightening roller group are staggered from each other along the horizontal direction. According to the on-line red steel elbow straightener, the problem that the head of a bar material which is discharged from a rolling machine is bent is solved, the yield is increased, a large amount of time and a large quantity of troubles are saved for the subsequent working procedure, and the logistics of the whole production loop is relatively smooth; and therefore, a phenomenon of repeated reversing is avoided, the production efficiency is improved, the manmade mixed steel risk is reduced, and the burden and the pressure of workers are reduced.

Description

technical field [0001] The invention relates to a straightening machine, in particular to an online red steel elbow straightening machine, which belongs to the technical field of metallurgical auxiliary equipment. Background technique [0002] When the bar passes through the rolling mill, due to uneven cooling, self-weight or the difference in the rolling line speed of the upper and lower rolls, etc., the head of the bar will bend after exiting the last stand rolling mill. In the past, the curved section of the round steel head could not be straightened online, and had to be straightened manually with an electric car in a cold state. However, it is very difficult to straighten the elbow of large-diameter cold steel, and it needs to be straightened by a separate car offline. , the straightening effect is generally difficult to meet the requirements of qualified products, and can only be treated as defective or waste products. Straightening machine is an equipment for online ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above disadvantages and provide an online red steel elbow straightening machine, which solves the problem of bending of the head of the bar after it leaves the rolling mill, improves the yield, makes the logistics of the production link smoother, and improves the production efficiency. efficiency
