Great Performance Of Fireclay Bricks

Fireclay bricks are used in construction of artificial small piece of material, is one of the world'soldest building materials. With clay (such as shale, coal gangue powder) as themain raw material, passthrough sludge processing, molding, drying and roasting completed. The main raw material of fire clay brick is nature or sandy clay,its main chemical composition is SiO2, Al2O3, Fe2O3 and crystallization water,because of the different geological formation conditions, may also contain asmall amount of alkali metal and alkaline earth metal oxides. The production technology of fire clay brick mainly includes soil, mud, blocking, drying,roasting, etc.

Great Performance Of Fireclay Bricks:

1.Fireclay bricks show weak acid under high temperature, alkaline slag erosion resistance is a bitpoor, but enhanced with Al2O3 content increase, and the thermal stability thansilica brick, magnesia brick as well.

2.The blast furnace fireclay brick of quality qualification goes through drying treatment, vacuum impregnation phosphate, secondary low temperature firing of phosphate impregnation products, can be used for laying on blast furnace lining.

3.Fire clay brick use local materials, cheap price, durable, and fire prevention,heat insulation, sound insulation and absorption of moisture, widely used incivil instruction engineering, waste brick bat also can make concrete aggregate.
