Steel ladle structure for small-pit-distance covered hot repair

Abstract

The invention relates to a steel ladle structure for a small-pit-distance covered hot repair. The steel ladle structure comprises a steel ladle body and a steel ladle cover, wherein the steel ladle body is arranged in a steel ladle tilting hot repair pit and is driven by a steel ladle tilting platform to rotate, and a tilting hook is arranged on the steel ladle body; the steel ladle body rotates towards the right for deslagging, the steel ladle body rotates towards the left for hot repair, namely the rotation direction of the hot repair of the steel ladle body is opposite to the rotation direction of deslagging; a left hinge shaft and a right hinge shaft are arranged at an opening of the steel ladle body, and a left hook and a right hook which are matched with the left hinge shaft and theright hinge shaft respectively are arranged on the steel ladle cover. When the steel ladle body rotates towards the right, the steel ladle cover is opened through the cooperation of the left hook andthe left hinge shaft in a rotating mode; when the steel ladle body rotates towards the left, the steel ladle cover is opened through the cooperation of the right hook and the right hinge shaft in a rotating mode. According to the steel ladle structure, the structure is safe and reliable to use, has convenient and fast refractory material inspection and deslagging functions, and can reduce the steel ladle hot repair labor intensity when the rotation direction of the steel ladle hot repair is opposite to the direction of the deslagging.

Description

technical field [0001] The invention relates to a ladle structure used for hot repairing of small pits with a cover, and belongs to the technical field of hot repairing of steel ladles in the steelmaking process. Background technique [0002] In order to reduce energy consumption, steelmaking plants gradually began to use the whole ladle capping technology. The application of this new technology has a great impact on the original steel ladle tipping hot repair process, because the direction of casting slag dumping is the running channel for hoisting and transporting steel ladles by the straddling crane. It is not conducive to ensuring the personal safety of hot repair personnel, so the hot repair of the ladle tipping platform using the whole ladle capping technology is often opposite to the direction of casting slag dumping.

AI Technical Summary

Problems solved by technology

The application of this new technology has a great impact on the original steel ladle tipping hot repair process, because the direction of casting slag dumping is the running channel for hoisting and transporting steel ladles by the straddling crane. It is not conducive to ensuring the personal safety of the hot repair personnel. Therefore, the hot repair of the ladle tipping platform using the whole ladle capping technology is often opposite to the direction of casting slag dumping.

[0003] However, when the direction of rotation of the ladle hot repair is opposite to the direction of slag dumping, the ladle with a cover cannot be repaired normally. The main problems are: (1) When the original pit layout of the hot repair of the ladle remains unchanged , there is not enough space for tipping with a cover, that is, when the tipping direction of the ladle hot repair is opposite to the direction of ladle slag dumping, it is impossible to realize the

(2) The hot repair of the ladle needs to open the lid to check the refractory condition in the ladle, the original pit opening space is not enough to open with the lid

[0004] In this regard, some steel mills have to use special equipment to uncover the ladle cover at the hot repair position, which cannot realize the hot repair of the ladle with cover
