Roller replacing device and method for replacing in-furnace roller components

Abstract

The invention discloses a roller replacing device and method for replacing in-furnace roller components and belongs to the technical field of ferrous metallurgy. The roller replacing device comprises a roller way rack, a roller replacing cross beam and at least two transmission devices, wherein the roller replacing cross beam is arranged on the roller way rack in a slidable way through the transmission devices; each in-furnace roller component is provided with a roller replacing base; the roller replacing bases are arranged on the roller way rack in a slidable way; and connecting mechanisms are arranged between the roller replacing bases and the roller replacing cross beam. The roller replacing device provided by the invention can be used for integrally replacing any one or more in-furnace roller components, thereby reducing the labor intensity and improving the inspection and repair efficiency; and meanwhile, the roller replacing device can be used for off-line inspection and repair of the in-furnace roller components so as to improve the inspection and repair quality. The roller replacing device not only solves the problems of high inspection and repair environment temperature and limited operation space in in-furnace roller replacement, but also is improved in universality so as to be capable of being widely applied to replacement of in-furnace rollers of heating furnaces.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and relates to equipment for replacing rollers in a heating furnace, in particular to a roller changing device and method for replacing any single or multiple roller assemblies in a furnace. Background technique [0002] At present, a plurality of independently driven furnace roller assemblies are arranged side by side on the furnace loading side and the furnace discharge side of the domestic hot rolling workshop line bar and section steel heating furnace. Drive device, one end of the roller can extend into the furnace, and the other end is connected with the drive device; it also includes two bearing seats for supporting the rotation of the roller at intervals on the roller near the side of the drive device . However, once the rollers in the furnace break down and need to be repaired or replaced, it is often difficult to pull the rollers out of the furnace. Usually, the roller...
