Double water-blocking hot roller way

Abstract

The invention relates to a double water-blocking hot roller way and belongs to the technical field of hot roller way equipment in the metallurgical industry. According to the technical scheme, a waterreturn chamber (6) is fixed on a bearing seat on one side of a transmission shaft (3) through a flange (7), a water inlet pipe (5) penetrates through the water return chamber (6) and a through hole in the transmission shaft (3) to extend into the cavity of a roller body (17), and a baffle (11) is fixed on the inner wall, close to the flange (7), of the water return chamber (6); a through hole matches with the transmission shaft (3) is formed in the baffle (11), and a water seal (12) is arranged in the through hole; an isolation plate (10) is fixed on the transmission shaft (3) between a bearing on one side of the transmission shaft (3) and the baffle (11), and a gap is arranged between the outer edge of the isolation plate (10) and the inner wall of the flange (7). With adoption of a double water-blocking structure, the double water-blocking hot roller way has the beneficial effects that the sealing effect is good, and accidents such as bearing blocking, roller way damage and the likecaused by the fact that water in the water return chamber enters the bearing can be avoided.

Description

technical field [0001] The invention relates to a double water-blocking hot-rolling roller table, which belongs to the technical field of hot-rolling roller table equipment in the metallurgical industry. Background technique [0002] In the metallurgical industry, the hot-rolled steel billet enters the furnace and the conveying roller table after the furnace works in a high-temperature and harsh environment. In order for the equipment to work normally, water cooling must be carried out. Commonly used cooling methods include external cooling and internal cooling. The water inlet and return water of the internal cooling roller table are set on the transmission side of the conveyor roller. After cooling, the cold water absorbs heat and turns into hot water, which is then discharged through the transmission side of the conveying roller. [0003] During the water return process, the hot water discharged from the transmission side of the conveying roller is collected in the retur...

AI Technical Summary

Problems solved by technology

[0003] During the water return process, the hot water discharged from the transmission side of the conveying roller is collected in the return water chamber first, and then discharged through the return water pipe. The distance between the return water chamber and the bearing on the transmission side of the conveying roller is very close. The water in the water chamber will seep out of the sealing structure and enter the bearing, causing water to enter the bearing and damage the lubrication, resulting in accidents such as bearing jamming and roller table damage
