Mullite brick has excellent high temperature performance, high strength, high refractoriness under load, excellent thermal shock stability, good chemical stability, and good corrosion resistance to acidic and low alkaline slag.
Mullite Bricks Properties:
Mullite brick is a kind of alumina-silica refractory product. It has features of high refractoriness, about 1790℃ above, low high temperature creep rate, and good volume stability. Because of the low expansion coefficient of the mullite, mullite brick is featured with good thermal shock resistance. Besides, it has high refractoriness under load, with the RUL starting point about 1600~1700℃. While the cold crushing strength is about 70～260MPa. It has high heat efficiency because of its good thermal conductivity. In addition, it is resistant to oxidation and corrosion.
Mullite Bricks Applications:
Mullite brick is widely used in the metallurgy industry, chemical industry, glass industry, and papermaking industry. In detail, it can be used in the following parts:
Hot air furnace, heating furnace, and soaking pit;
Hearth and bottom of the large scale blast furnace;
Roof of the steelmaking furnace, and electric furnace;
Lining and furniture of the ceramic kiln;
Regenerator of the glass furnace, and ling of the cement kiln;
Torpedo car, heat treating furnace, heating furnace;
Converter, and cracking furnace, etc.
