Water-cooling rotary joint used for fan-shaped section drive roller of continuous casting machine

Abstract

The invention discloses a water-cooling rotary joint used for a fan-shaped section drive roller of a continuous casting machine. The water-cooling rotary joint comprises a roller sleeve, a left joint and a right joint, wherein each of the left joint and the right joint comprises an outer side cylindrical section and an inner side conical section; the left joint and the right joint are symmetrically arranged at the two sides of the roller sleeve, and are matched with the inner wall of the roller sleeve; the outer side end surface of the left joint and the outer side end surface of the right joint are connected with positioning plates; the inner side end surface of the left joint and the inner side end surface of the right joint are connected with flexible sealing plates; a bearing is arranged between the outer side cylindrical section and the inner wall of the roller sleeve, and the outer side cylindrical section and the inner wall of the roller sleeve are fixedly connected through a bearing end cover; the outer side center of the positioning plate of the left joint is connected with a water inlet tube; and the outer side center of the positioning plate of the right joint is connected with a water outlet tube. The water-cooling rotary joint disclosed by the invention improves roller sleeve cooling efficiency and prolongs the service life of the drive roller.

Description

technical field [0001] The invention belongs to the technical field of rotary joints, and in particular relates to a water-cooled rotary joint used for drive rollers of sector segments of continuous casting machines. Background technique [0002] Continuous casting machine segment drive roller is the core equipment of continuous casting machine, mainly used for stretching and straightening of continuous casting slab, its running stability and dimensional accuracy have a decisive influence on the quality of casting slab. Since the driving roller runs at high temperature for a long time, cooling water must be used to cool it. However, the existing rotary joints have problems such as short service life and easy water leakage, which leads to insufficient cooling efficiency of the driving roller, and often causes failures such as foot roller breakage. Therefore How to develop a rotary joint with good sealing performance will greatly promote the technological progress of the indus...
