Guide section device for billet continuous casting machine

Abstract

The invention discloses a guide section device for a billet continuous casting machine, relates to a billet continuous casting machine system and aims to solve the problems of short service life, complex assembly and disassembly and the like of a guide roller in the conventional guide section device for the billet continuous casting machine. The guide section device for the billet continuous casting machine comprises a guide roller base and a guide roller. The guide roller base is fixed on a structural platform. The guide roller is arranged on the guide roller base. The guide section device for the billet continuous casting machine is characterized in that: the guide roller comprises a water-cooled bearing support, a roller bearing, a roller and a rotary joint; the roller is arranged on the water-cooled bearing support by the roller bearing; a water cooling passage is formed in the roller; the rotary joint is arranged at one end of the roller and is communicated with the water cooling passage. In the device of the invention, the guide roller has a water cooling structure and long service life and is convenient to assemble, disassemble and maintain so as to improve the continuous working time of the whole continuous casting machine.

Description

technical field [0001] The invention relates to a continuous casting machine system, in particular to a guide section device for a billet continuous casting machine. Background technique [0002] The guide section device of the billet continuous casting machine is a device that guides the billet out of the mold so that it enters a specific processing area. Since the guide section device is in direct contact with the high-temperature casting slab, the guide rollers in the guide section have a short lifespan, wear quickly, and even have problems that the rollers are bonded to their rotating shafts shortly after work. Therefore, a working life The longer guide section device is an important means to increase the continuous working time of the continuous casting machine. [0003] At present, the domestically designed guide section device adopts self-lubricating bearings, its structure is too simple, and it lacks a reliable cooling method, the life of the guide roller is short, ...

AI Technical Summary

Problems solved by technology

[0003] At present, the domestically designed guide section device adopts self-lubricating bearings, its structure is too simple, and lacks reliable cooling methods, the life of the guide roller is short, and the disassembly and assembly are complicated

In addition, there is no pressure roller, so that the shape and quality of the billet cannot be guaranteed

The guide section device designed abroad can better solve the above problems, but because of the use of the overall frame structure and airbag pressure roller, the cost is relatively high, and it cannot be widely promoted in China
