Refractories (Refractory material) selection and matching recommendation (a) burning on both sides of the transition zone within the band and have a stable kiln skin site should cast refractory brick manufacturers, including magnesia-chrome brick, low chromium and chromium-free containing zirconium and zirconium-free as well as all kinds of special brick dolomite bricks. On the production capacity of small, low-temperature kiln, open quite yet more frequent high alumina brick kiln can also be used, mainly phosphate bonded alumina bricks. Refractories (Refractory material) kind of an acidic refractories (Refractory material) usually refers to the SiO2 content of more than 93% of refractories (Refractory material) Which cast refractories have to sell, its main feature is the high temperature resistant to acidic slag erosion, but easy to react with alkaline slag. 2, basic refractory (basic refractory) generally refers to magnesium oxide or magnesium oxide and calcium oxide as the main component of refractories (Refractory material). Such refractories (Refractory material) are high refractoriness refractory casting agent, resistance to strong alkaline residue. 3, aluminum silicate refractories (Refractory material) refers to the SiO2-Al2O3 as a main component of refractories (Refractory material), their number can be divided into half-Al2O3 content siliceous (Al2O3 15 ~ 30%), clay Quality (Al2O3 30 ~ 48%), high alumina (Al2O3 greater than 48%) categories. 4, fused cast refractories (Refractory material) refers to a certain method after the high temperature batch material melted, cast into the refractory article having a certain shape.
