Magnesium bricks belong to alkaline refractory materials and have strong resistance to alkaline slag, but cannot resist the erosion of acidic slag. At high temperatures of 1600 ℃, they can react chemically with silicon bricks, clay bricks, and even high alumina bricks.
Refractory Castable is a material that plays an important role in the high temperature industry. It is an amorphous refractory material made of refractory aggregates, powders, binders and admixtures mixed in a certain proportion.
Refractory prefabricated parts are functional materials developed on the basis of traditional indefinite casting materials, and are high-temperature materials in the category of refractory castables. It is made of refractory aggregates, powders, binders, additives, water or other liquids and cast into a fixed shape by the casting method. According to the different binders, it is divided into refractory cement bonding, phosphate bonding, water glass bonding, cement-free bonding, etc. According to the material, it can be divided into high alumina prefabricated parts, corundum prefabricated parts, clay prefabricated parts, mullite prefabricated parts, etc.
Silica bricks are divided into general silica bricks, silica bricks for glass kilns, silica bricks for coke ovens, and silica bricks for hot blast furnaces according to their uses.
High-alumina bricks refer to silicon-aluminum refractory bricks with an aluminum content of ≥48%. High-alumina bricks are widely used in blast furnaces, hot blast furnaces, electric furnaces, anode roasting furnaces, molten iron ladles, rotary kilns, glass kilns and other high-temperature kilns, with a wide range of types, common high-alumina bricks are ordinary high-alumina bricks, low-creep high-alumina bricks, mullite bricks, andalusite bricks.
Lightweight mullite brick ingredients: The production of lightweight mullite bricks uses sawdust, foamed polystyrene granules and their mixtures as additives for burning. Ingredients according to the formula, when batching, first dry mix clinker, industrial alumina and kaolin in the mixing tank for 2-3 minutes according to the proportion, and then add additives and binders (additional), stir while adding, and use the trapped material for 24 hours after stirring well.
