VI. Practical application cases

(1) High strength mullite castable:

In the lining of electric furnace and smelting furnace in a large mining and smelting enterprise, high-strength mullite castable shows extremely high thermal shock resistance and high-temperature stability, which significantly prolongs the service life of the equipment.

In the high-temperature kiln of a cement production enterprise, high-strength mullite castable was used as lining material, which successfully reduced energy consumption and maintenance cost.

(2) Steel fiber reinforced refractory castable:

In the industrial environment that needs to withstand high temperature, mechanical wear and material erosion, steel fiber reinforced refractory castable is widely used in ladle lining, blast furnace taphole and other parts.

Refractory castable can meet the needs of different industrial fields and become an indispensable material in high temperature industry because of its diverse types and excellent properties.
