Problems solved by technology

[0003] At present, the permanent lining of molten iron tanks or ladles in the metallurgical industry is made of refractory casting. The entire furnace building process is complicated, which wastes energy and prolongs the furnace building period. Moreover, the binder used for pouring refractory materials is cement, etc., so in A certain amount of water must be added during construction, and the castable will form pores of different sizes during the drainage proc

Description

technical field [0001] The invention relates to the field of refractory materials, in particular to a filled refractory material used for permanent lining of tanks containing high-temperature liquids such as molten iron tanks and ladles. Background technique [0002] Hot metal tanks or ladles are special containers for high-temperature liquid metal in iron and steel metallurgical enterprises. The inner refractory lining is composed of a permanent lining and a working layer. The permanent lining is close to the outer wall of the metal, and the working layer is in direct contact with liquid iron or steel. Floor. [0003] At present, the permanent lining of molten iron tanks or ladles in the metallurgical industry is made of refractory casting. The entire furnace building process is complicated, which wastes energy and prolongs the furnace building period. Moreover, the binder used for pouring refractory materials is cement, etc., so in A certain amount of water must be added ...
