Billet overturning and straightening device

Abstract

The invention relates to a billet overturning and straightening device. The billet overturning and straightening device comprises a hollow turbine box, wherein the hollow turbine box is provided with a hollow cylinder structure, a turbine and a worm; an annular plate body is arranged at the end part of the hollow cylinder; an opening is formed in the circle center part of the annular plate body; the turbine is connected to the outer side of the hollow cylinder in a sleeving manner; the worm is positioned below the turbine; the turbine is connected with the worm in a meshing manner; and a clamping device is arranged on the annular plate body. The billet overturning and straightening device overturns around the center in situ, so that collision with a roller bed surface is avoided, surface damage of a continuous casting billet can be relieved, and the surface quality of the continuous casting billet is improved. Continuous conveying and overturning of the billet can be realized, the overturning and drying efficiency is improved, and energy consumption is reduced; and the turbine and the worm are not directly exposed outside, so that the influence of the surrounding environment is small.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, in particular to continuous casting slab heat treatment equipment, and relates to a steel slab turning and straightening device. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] In order to prevent the curved continuous casting slab from entering the heating furnace and causing damage to the heating furnace, steel production enterprises will install a casting slab turning device on the roller table in front of the heating furnace. At present, most domestic production enterprises use pliers-type steel turning machines or hydraulic steel turning machines. The tong-type steel turni...

AI Technical Summary

Problems solved by technology

[0004] But there are following problems in existing pliers-type steel turning machine and hydraulic steel turning machine: (1) when the steel turning machine moves, because the direction is uncertain or it is not easy to grasp the slab, it is easy to collide with the surface of the roller table, which easily causes the conveying roller to be damaged. wear, and reduced the surface quality of the slab; (2) the billet must be stopped to actually turn over the steel when the turning machine is turned over, thereby reducing the efficiency of turning over; (3) the existing pincer type turning machine and hydraulic turning The steel machine cannot be fully enclosed, resulting in a poor surrounding environment and failing to meet the problem of cleanliness and environmental protection
