Background
In a converter lining, a tap hole is used as a necessary passage for molten steel to enter a steel ladle from a converter, and the working condition is quite severe due to the frequent effects of high-temperature molten steel scouring, slag corrosion, mechanical stress damage and the like, so that the phenomenon of too high expansion rate of the inner diameter of the tap hole can often occur, and the steel is caused
The tapping time is shortened due to the increased flow, and the tapping hole sleeve needs to be replaced by heat in order to ensure the product quality of the converter.
At present, the filling and repairing materials commonly used for replacing the steel tapping hole of the domestic converter mainly have two modes of the traditional dry-process gunning materials and the magnesium-chromium castable. The traditional dry-process gunning material is used for filling and repairing a converter steel-tapping hole, has the characteristics of simple and flexible operation and the like, but is gradually eliminated because of the problems of short gunning and water mixing time, non-uniformity, loose material structure and air gap generation and strength reduction caused by the fact that the gunning and water mixing time is short and non-uniform and the material structure is poor in anti-stripping performance and the like due to the fact that the gunning is added, the water adding amount is uncertain and the granularity is too fine. The magnesium-chromium castable is adopted, the service life of a steel-tapping hole is greatly prolonged, but due to the limitation of the hot repair condition of a converter, shovels are manually used for stirring on site, then a trolley is used for pushing the stirred castable into the converter, and then the castable is put into the converter in a manual material turning mode, so that the castable cannot completely and accurately enter a gap between a steel-tapping hole sleeve and a brick cup due to the influence of high temperature of a furnace lining and inaccuracy caused by remote throwing construction.
The utility model discloses a converter steel-tapping hole grouting guide slot in patent No. 2021218380439, this utility model has solved to a certain extent and has changed the artifical stirring mode of steel-tapping hole sleeve pipe and has dropped into the degree of difficulty in the stove with the pouring material, can simplify the grout operation step, reduces the grout time, improves the grout quality, improves the factor of safety of grout operation. However, according to the scheme, a shovel is still required to be used manually for stirring, the steel-tapping hole grouting guide groove needs to be placed into the converter manually and cannot move and rotate freely, the labor intensity of operators is high, the accuracy of pouring materials entering a gap between the steel-tapping hole sleeve and the brick cup is still limited, the steel-tapping hole grouting guide groove is affected by high temperature of a furnace lining, the steel-tapping hole grouting guide groove is extremely prone to deformation, and the service life is short.
