Abstract

The invention belongs to the technical field of steel deep processing, and particularly relates to a rolling-type portal groove steel low-temperature correction device. The rolling-type portal groovesteel low-temperature correction device comprises a workbench used for transporting portal groove steel and providing a mounting position, an inner side correction roller assembly mounted on the workbench and used for correcting inner side leg flanges of the portal groove steel, a side edge correction roller assembly mounted on the workbench and used for correcting an outer side leg flange on oneside of the portal groove steel and a unilateral flange on one side of the portal groove steel, and a combined correction roller assembly mounted on the workbench and used for correcting an outer sideleg flange on the other side of the portal groove steel and a unilateral flange on the other side of the portal groove steel. The problem of finished steel product deformation can be solved, use performance of the portal groove steel is guaranteed, it is guaranteed that the steel meets the requirements of size and surface flatness and roughness, and the characteristics of high correction efficiency and high shaping precision are achieved.

Description

technical field [0001] The invention belongs to the technical field of deep processing of steel materials. Specifically, the invention relates to a low-temperature straightening device for rolling gantry channel steel. Background technique [0002] Mast channel steel is a special-shaped steel used for lifting and lowering the fork in the production of forklifts, such as Figure 8 As shown, the cross section of the steel is h-shaped, the upper part of the h-shape is called a single side, the two sides of the lower part of the h-shaped opening are called legs, the side walls of a single side are called single-sided flanges, and the side walls of the legs are called is the leg flange, the leg flange on the opening side is the inner leg flange, and the corresponding one is the outer leg flange. Since the cross-section of the special-shaped steel is H-shaped and not evenly distributed, the steel is not uniformly stressed during rolling. After cutting to length, the steel is pron...
