Description

Sell industry furnace lining use sintered mullite refractory brick 1. Definition: Mullite refractory brick is mainly made of synthetic mullite as the raw material, and mullite as the host lattice. 2. Chemical formula: 3Al2O**2SiO2. 3. Classification: Sintered mullite brick Casting mullite brick 4. Raw materials of sintered mullite brick. 1). Natural high-alumina bauxite and kaolin, 2). Industrial alumina and clay (kaolin or agalmatolite ) 5. Production technology Select pure raw material, proportion according to the theory consist of the mullite, produced through the process of fine grinding, ball forming (block forming), calcining with the high temperature. 6. Highlight: 1). High temperature creep property is better than the one of alumina brick made of the natural clay as raw material. 2). Refractoriness of it is better than the ones of siliceous and magnesia products. 3). Resistant erosion to acid and low alkali slag properties of it is stronger than the one of the magnesia products. 7. Properties: (See attached table) 8. Application: Mainly used in constructing of the roof of the hot blast furnace, body and bottom of blast furnaces, dead angle lining of regenerator of the glass smelting kiln, ceramic sintering furnace, petroleum properdin system.
