Description

Ladle with quick repair function Technical Field The utility model belongs to the technical field of metal smelting, and particularly relates to a ladle with a rapid repairing function. Background The ladle is an important thermal equipment in the metallurgical industry, and is mainly used for receiving, transporting and transferring high-temperature molten iron after tapping of a blast furnace, and completing transfer and pouring operations of the molten iron in a steelmaking or casting process. As a key container for connecting iron making and steelmaking processes, a ladle is subjected to high-temperature molten iron erosion above 1400 ℃ for a long time, and is subjected to frequent temperature shock and mechanical impact, and the lining quality directly determines the service life, production safety and operation economy of equipment. The integral castable lining and the refractory brick masonry lining commonly adopted in the industry at present have obvious defects. The integral castable lining is integrally formed by adopting refractory castable at one time, and has compact and seamless structure, but when local damage occurs in the use process, the integral castable lining is required to be removed and re-poured, so that not only is the material wasted, but also the material is required to undergo a long baking and curing process, and the production continuity is seriously affected. Although the lining for building the refractory bricks can be partially replaced theoretically, the refractory bricks are fixed in specification, the building process is complex, large-area intact brick bodies are required to be removed for reaching damaged parts in actual maintenance, and the molten iron infiltration and the loosening of the structure are easy to be caused due to excessive number of brick joints. These two kinds of traditional lining structures all are difficult to realize quick, accurate local restoration, lead to ladle maintenance cycle long, use cost is high enough, have restricted metallurgical enterprise's production efficiency and have promoted. Disclosure of utility model The utility model provides a ladle with a rapid repair function, which is used for solving the problems that the prior ladle lining structure in the background art needs to be removed integrally for pouring again when being partially damaged and the leakage of molten iron is caused by too many brick joints. The utility model adopts the technical scheme that the ladle with the rapid repairing function comprises a shell, wherein an insulating layer and a working layer are sequentially arranged in the shell from outside to inside, the working layer comprises a pouring material layer, a ladle wall precast block, a corner precast block and a ladle bottom precast block, wherein the pouring material layer is close to a ladle nozzle area and surrounds the pouring material layer, the ladle wall precast block is close to a ladle wall position, the corner precast block is positioned between the ladle wall and the ladle bottom, the ladle bottom precast block is positioned in the center of the ladle, the ladle wall precast block is uniformly distributed around the center of the ladle and is provided with a plurality of layers along the height direction of the ladle, the ladle wall precast block comprises a first precast block and a second precast block, the first precast block is detachably connected with the second precast block, the first precast block is provided with a first side face and a second side face which are mutually parallel, and the second precast block is provided with a third side face and a fourth side face which are mutually included angles; After the first prefabricated block and the second prefabricated block are assembled to form the wall-covering prefabricated block, the second side face and the third side face are mutually attached, the extension lines of the first side face and the fourth side face are mutually overlapped with the center of the shell, and the arc length of the outer wall of the second prefabricated block is smaller than the integral arc length of the inner wall of the wall-covering prefabricated block after being combined. The third side of second prefabricated section outwards extends the shaping and has T type piece, and the second side of first prefabricated section is equipped with T type groove with T type piece assorted. The T-shaped groove is formed in the back surface of the first precast block. The corner precast block is provided with a plurality of and evenly distributed around the center of the shell, and the inner side corner position of the corner precast block is in an arc-shaped structure.
