Brick building process of bottom of steel ladle

Abstract

The invention discloses a brick building process of the bottom of a steel ladle. The brick building process comprises the following steps of: dividing the bottom of the steel ladle into a plurality of square-shaped prebuilding block areas, manufacturing a corresponding mold according to the plurality of square-shaped prebuilding block areas, then manufacturing corresponding prebuilding blocks in the mold, and lifting the prebuilding blocks into the corresponding square-shaped prebuilding block areas after the prebuilding blocks are integrated. According to the brick building process, the prebuilding can be carried out on the bottom of the steel ladle in the prebuilding block mold, so that an operator can operate without needing to wait for cooling of the steel ladle, and the brick building process is very beneficial to reasonable arrangement of the building production tasks of the steel ladle. Simultaneously, according to the process, the building quality of the bottom of the steel ladle also can be improved, the labor intensity of workers is reduced and the potential safety hazard of the workers is reduced.

Description

technical field [0001] The invention relates to a steel ladle for carrying molten steel, in particular to a process for building the bottom of a ladle with refractory bricks. Background technique [0002] Ladle is a container for carrying molten steel and refining outside the furnace. It is an indispensable tool for transportation, refining outside the furnace and pouring molten steel in the process of connecting the converter to the continuous casting steelmaking production process. The working layer at the bottom of the ladle is built with refractory bricks. Analyzing the current technology of building bricks at the bottom of the ladle, it mainly has the following deficiencies: [0003] 1. Operators must wait until the ladle is off-line and cooled enough to enter the bottom of the ladle. Moreover, the construction of the bottom working layer of each ladle requires 4 workers, and it takes an average of 4 hours to complete. The operation efficiency is low, which is not condu...

AI Technical Summary

Problems solved by technology

[0003] 1. Operators must wait until the ladle is off-line and cooled enough to enter the bottom of the ladle. Moreover, the construction of the bottom working layer of each ladle requires 4 workers, and it takes an average of 4 hours to complete. The operation efficiency is low, which is not conducive to the turnover of the ladle ;

[0004] 2. There are many brick joints in the masonry of the bottom-covered bricks. During the masonry process, it is necessary to use a wooden hammer to knock the bottom-covered bricks, which will easily displace the finished bricks. Therefore, it is difficult to control the quality of the brick joints. There are quality and safety hazards;

[0005] 3. During the online use of the ladle, the residual thickness of the refractory material is judged based on the datum level of the ladle bottom. However, in the current masonry mode, the datum level of the ladle bottom is not very smooth, which may cause errors in the residual thickness. It is judged that there are certain hidden dangers in production safety;

The labor intensity of the operators is relatively high, and there is a hidden danger of slipping and falling when climbing the bamboo ladder up and down the steel ladle
