Repairing method for ladle working lining bricks

Abstract

The invention relates to the technical field of repairing of ferrous metallurgy ladle inner linings, and discloses a repairing method for ladle working lining bricks. The repairing method comprises the step S1: selecting excavating and repairing equipment by structural parameters of the working lining bricks and structural parameters of corresponding pores in the working lining bricks; the step S2: performing presetting treatment on the pores by utilizing the excavating and repairing equipment, and installing repairing packing in the pores obtained after presetting treatment; and the step S3:baking a repaired ladle for later use. According to the repairing method for the ladle working lining bricks provided by the invention, the pores of the working lining bricks are treated by selectingthe suitable excavating and repairing equipment, and the pores are repaired with the repairing packing and baking is performed, so that the overall structure of a ladle working lining is reserved to the greatest extent; the problem that the continuous service life of the repaired ladle is short is solved, and meanwhile, losses of refractory materials of ton steel are reduced, and the overall refractory material consumption is reduced; and in addition, the repairing method is fast, convenient, energy-saving and environmental-friendly, and can achieve a good effect during 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
