Two-rack reversible rolling device for rolling square and flat steel and steel rolling method thereof

Abstract

The invention provides a two-rack reversible rolling device for rolling square and flat steel and a steel rolling method of the two-rack reversible rolling device, and belongs to the technical field of steel rolling. The two-rack reversible rolling device comprises racks and a guide and guard device, and is characterized in that the guide and guard device is connected with a rolling mill in a spacing-adjustable clamping plate manner and a hydraulic driving and locking fixing combined manner. The two-rack reversible rolling method can be well used for rolling the square and flat steel, a guideroller gap of the device is high in positioning precision and strong in supporting force, the rolled square and flat steel is good in appearance and high in precision, meanwhile, stable operation of aworkpiece on a roller way can be well guaranteed, and the quality problems of rhombus, distortion, mistaken hole pattern entering of rolled pieces, oblique bending or disordered penetration on the plane of the rolling mill and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, and in particular relates to a two-stand reversible rolling device for rolling square flat steel and a steel rolling method thereof. Background technique [0002] The blanking machine is a two-roll reversible rolling mill, suitable for rough rolling, and is an ideal rolling mill equipment for rolling plain carbon steel, alloy steel, stainless steel, high-temperature alloy, copper, aluminum, etc. At present, the rolling mill equipment that realizes the metal rolling process is mainly composed of a motor, a reducer, a two-roll reversing rolling mill, a turning machine, and a guide device. [0003] The existing steel rolling process generally uses multiple rolling units for continuous rolling. In the continuous rolling production line, the continuous rolling unit is the core equipment of the entire production line and the key to the stable operation of the entire production line. The equipment...

AI Technical Summary

Problems solved by technology

In the rolling process, there are various deficiencies because the guide plates of each hole are not fixed

Moreover, in modern rolling mills, the feeding speed of the finishing stand is very high, and it is prone to failures that cause the rolled piece to enter the pass and "bend" or pass randomly on the plane of the rolling mill. It will also cause a lot of loss and waste in terms of production time and materials

At the same time, the existing structure of the guide plate of the rolling mill is also difficult to realize the rolling of square flat steel, because the positioning accuracy of the guide roll gap is not high, the rolled piece is prone to deformation and unevenness, and the rolled square flat steel has a poor appearance , low precision and other issues

Therefore, the existing rolling mill structure needs to be improved urgently
