Fused silica brick has better thermal shock resistance, much lower thermal expansion, and can be used to do hot repair. Fused Silica Brick for Hot Repair of Coke Oven is similar to general silica brick, but it has better thermal shock resistance. The property of fused silica brick is similar to general silica brick, but it has better thermal shock resistance, much lower thermal expansion and it can stand suddenly change of temperature. It also can be heated in very short time after buildup and do not need to calculate thermal expansion. So we can directly use its cold size for masonry. Put on wooden pallets, tightened with iron stripes, covered with plastic bag, warped with film, shipped in pallet by container. Do corner protection and other measures to avoid products from breaking. And these packages should be under ISPM standard.
High Alumina Bricks for general uses are made from bauxite of super quality, bonding chamotte and additives. It is noted for good erosion resistance high refractorinessthermal shock resistance and accurate dimension. They were widely accepted in various kilns ,thermal equipment of metallurgy, petroleum, chemical industrysuch as high aluminum bricks for blast furnaces steel ladle and electrical furnace and so on .
Features 1. Low bulk density, low thermal conductivity, good thermal insulation performance. 2. Refractory category allow direct contact of fire, suitable ofr various atmosphere 3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely 4. Can be used in various kilns because of its cheapness and general tray package. Applications 1. Furnaces of metallurgy industry, heat treatment furnace 2. Furnaces of chemical industry and construction industry. 3. Furnace of incineration of garbage, recirculating fluidized bed furnace Standard sizing: 230 x 114 x 65 mm others up to the client. packed on wooden pallets, with water-proof cover, and tightened with plastic/steel bandages.
