The ladle is a container of molten steel. The commonly used refractory materials are alumina magnesia spinel ladle castable, magnesia alumina spinel brick, ladle lining brick, etc. Use of alumina magnesia spinel can provide flaking resistance of refractory materials.
Alumina magnesia spinel castable is also called corundum or high alumina magnesia spinel refractory castable, also called composite alumina magnesia spinel refractory castable. It has excellent functions and is used in large and medium sized ladle.
Magnesia alumina spinel has excellent corrosion resistance, strong corrosion resistance, good slag resistance, anti abrasive ability, good thermal shock resistance and high temperature resistance. It is the ambition material for the high temperature belt of cement rotary kiln with magnesia alumina spinel brick, ladle lining refractory brick, ladle castable and other refractory products. Magnesia alumina spinel is widely used in refractory materials, steel exercise, cement rotary kiln and glass industrial furnaces.
1. Aluminium-magnesium spinel ladle castable is a kind of special grade bauxite, corundum, high-purity spinel as the main material, and participates in the mixing of appropriate additives and dispersants. High density and durability;
2. Ladle castables should be stored in warehouses with rainproof equipment and monotonous ventilation according to the varieties and trademarks. Beware of moisture, prevent prolonged agglomeration, chemical bond failure, and affect the application effect.
3. In the case of better storage conditions, the shelf life is half a year. After half a year, the physical and chemical function indicators need to be checked. Once the requirements are met, they can be used as usual.
