Description

technical field

[0001] The invention relates to a refractory material lining gunning repair material, in particular to a torpedo tank lining gunning repair material and its preparation method and application, belonging to the technical field of torpedo tank refractory materials for transporting molten iron. Background technique

[0002] The torpedo tank has become one of the main thermal equipment for the transportation of molten iron between the iron-making blast furnace and the steel-making converter in domestic and foreign iron and steel enterprises due to its advantages of large molten iron loading capacity, high transportation efficiency, good thermal insulation performance, lower temperature of molten iron, and long service life. , the middle section is cylindrical, and the two ends are conical truncated cones. The shape is similar to a torpedo, so it is called a torpedo tank. Due to the irregular shape of the torpedo tank, the refractory lining of the torpedo tank is ...
