Heating furnace discharged ground roller cooling structure

Abstract

The invention discloses a heating furnace discharged ground roller cooling structure which comprises a base and a steel tapping roller mounted on the base. The steel tapping roller comprises a hollowrotating shaft and an annular transport groove arranged on the hollow rotating shaft in a sleeving manner, and the transport groove is fixedly connected to the hollow rotating shaft and is used for carrying and conveying continuous cast steel billets; and the hollow rotating shaft is internally provided with a cooling water pipe, and the end, outside the hollow rotating shaft, of the water pipe isconnected to a water conveying pipe. An existing solid shaft is replaced with the hollow rotating shaft, the cooling water pipe is led into the rotating shaft so as to supply cooling water, heat received by a discharged ground roller is continuously brought away through the cooling water, the discharged ground roller is kept to run at the relatively lower temperature, and the condition that the ground roller is stuck due to high-temperature evaporation of lubricating oil is effectively avoided.

Description

technical field [0001] The invention relates to the field of iron and steel smelting and processing, in particular to a cooling structure for a roll of a heating furnace. Background technique [0002] After the continuous casting billet comes out of the furnace, it is transported to the subsequent processing section through the track formed by the ground rollers laid on the ground. Since the heating furnace maintains a high temperature state for a long time, it is inevitable that more heat will be received by the discharge floor rollers near the furnace door. The ground rollers that have been baked out of the oven are baked at high temperature for a long time, and the lubricating oil in the ground roller bearings is easily volatilized and consumed, resulting in the ground rollers often being stuck due to lack of sufficient oil lubrication. Simply relying on artificially increasing the frequency of oil replenishment cannot completely solve the problem of ground roller bearin...

AI Technical Summary

Problems solved by technology

The ground rollers baked at high temperature for a long time, the lubricating oil in the bearings of the ground rollers is easily volatilized and consumed, resulting in the ground rollers often being stuck due to lack of sufficient oil lubrication

Simply relying on artificially increasing the frequency of oil replenishment cannot completely solve the problem of ground roller bearing jamming

The jamming of the out-of-the-box floor rollers led to the interruption of maintenance of the production line, which seriously affected the normal production, and also increased a lot of workload for the maintenance personnel
