A method for repairing ladle lining bricks

Abstract

The invention relates to the technical field of ladle lining repair in iron and steel metallurgy, and discloses a method for repairing working lining bricks of ladles, including step S1: selecting digging and repairing equipment through the structural parameters of the working lining bricks and the structural parameters of the corresponding holes and seams on the working lining bricks ; Step S2: Presetting the holes and seams by using the digging and mending equipment, and installing the repair filler in the pre-treated holes and seams; Step S3: Baking the repaired ladle for later use. The method for repairing the working lining bricks of the ladle provided by the present invention is to process the pores of the working lining bricks by selecting suitable excavating and mending equipment, and to repair and bake the pores with the repairing filler, so as to retain the overall structure of the working lining of the ladle to the greatest extent , solves the problem of continuous service life of the ladle after repair, reduces the loss of refractory materials per ton of steel, and saves the overall consumption of refractory materials. In addition, this repair method is fast, convenient, energy-saving and environmentally friendly, and can achieve good results in actual use.

Description

technical field [0001] The invention relates to the technical field of iron and steel metallurgical ladle inner lining repair, in particular to a method for repairing working lining bricks of a ladle. Background technique [0002] Ladles, also known as ladles, ladles, etc., are used to hold molten steel. In the ladle, the molten steel is also refined, the temperature of the molten steel is adjusted, and the process is buffered. It is an important metallurgical equipment for continuous casting and rolling. For the entire enterprise, the application of ladle not only speeds up the production pace, but also improves the overall metallurgical production efficiency, which provides great help for the enterprise to efficiently produce clean steel. [0003] At present, magnesia-carbon bricks are mainly used in the ladle slag line, and aluminum-magnesia-carbon bricks are mainly used in the wall and bottom parts of the ladle. There will be a series of problems during the continuous tu...

AI Technical Summary

Problems solved by technology

[0003] At present, magnesia-carbon bricks are mainly used in the ladle slag line, and aluminum-magnesia-carbon bricks are mainly used in the wall and bottom parts of the ladle. There will be a series of problems during the continuous turnover of the ladle, and the most serious one is the work of the ladle. When the lining part is used for a few furnaces or more than a dozen furnaces, there will be round hole seam erosion, and the residual thickness of the overall working lining can fully meet the requirements of use. Usually, the maintenance method of the refractory material manufacturer is mainly to dismantle the whole and then rebuild the masonry. Large, and troublesome to operate, while causing waste of resources and polluting the environment
