A slab conveying device that realizes uniform speed and synchronization

Abstract

The invention relates to a constant-speed synchronous conveying device for slabs. The constant-speed synchronous conveying device for the slabs comprises a concentrated roller bed and a transmission device. The concentrated roller bed comprises a bottom frame, a plurality of roller assemblies and a synchronizing shaft located on the same side of all the roller assemblies. Each roller assembly comprises a roller, a bearing seat and a bearing. The constant-speed synchronous conveying device for the slabs further comprises bevel gear pairs, wherein the number of the bevel gear pair is equal to that of the roller assemblies. Each bevel gear pair comprises a first bevel gear and a second bevel gear. The synchronous shaft is in key joint with all the first bevel gears. Each roller is in key joint with the corresponding bevel gear. The speed ratio of each bevel gear pair is 1:1. One roller assembly is a driving roller assembly. The transmission device is connected with the driving roller assembly. By the adoption of the constant-speed synchronous conveying device for the slabs, the special use requirements of a clearing system in a slab caster are met, the rotation speeds of all the rollers are identical through the concentrated roller bed and the transmission device, the speeds of the slabs to pass through a scarfing machine are identical, so that the scarfing depths of the slabs are identical, and the quality of the slabs can be improved.

Description

technical field [0001] The invention relates to the technical field of slab continuous casting cleaning systems, in particular to a slab conveying device capable of realizing uniform speed synchronization. Background technique [0002] At present, in the severe situation of excess production in the steel market, improving product quality is an effective means to improve competitiveness and ensure profit margins. The flame cleaning machine can clean the surface of the slab and effectively improve the surface quality of the slab. However, when the slab is transported in the working area of ​​the cleaning machine for flame cleaning, it must be ensured that the conveying speed of the slab remains constant and synchronous. Under certain circumstances, the surface cleaning depth is shallow when the slab conveying speed is fast, and the surface cleaning depth is deep when the speed is slow, which cannot achieve the purpose of improving the surface quality of the slab. At present, ...
