Product Description Product Description High alumina refractory brick is made of high bauxite as the main raw material, adding composite binder, and sintering at high temperature by strengthening the tight bonding of matrix and particles. It has the characteristics of high compressive strength, high softening temperature under load and resistance to spalling. Is currently cost-effective and commonly used stereotyped refractory products, more than 80% of the domestic kiln will use this product, very suitable for CFB boiler and other thermal kiln lining use. Detailed Photos Characteristic & ApplicationProduct features:1. Refractoriness; The refractoriness of high aluminum brick is higher than that of clay brick and semi-silicon brick, up to 1750-1790oC.2, soft load temperature: Because the aluminum oxide content in high aluminum brick products is high, less impurities, the formation of fusible glass body is less, so the soft load temperature is higher than the clay brick, the soft load temperature of high aluminum products is generally above 1420-1550oC. However, because the mullite crystals did not form a network structure, the soft load temperature is still not as high as the silicon brick.3, slag resistance; High aluminum bricks have more aluminum oxide, close to neutral refractory materials, which can resist the erosion of acidic slag and alkaline slag, because of the presence of silica, so the ability to resist alkaline slag is weaker than the ability to resist acid slag4, chemical attack resistance: high aluminum refractory products resist acid or alkaline slag, metal erosion and oxidation, reduction reaction are very good, and with the increase of aluminum oxide content, the reduction of impurities and strengthen.Typical applications:Mainly used for laying blast furnace, hot blast furnace, electric furnace top, blast furnace, reverberatory furnace, rotary kiln lining. In addition, high aluminum refractory brick is also widely used as open hearth regenerative lattice brick, plug head for pouring system, water brick and so on.Product ParametersIndicators/ProjectsGL85GL75GL65Al2O3,% ≥857565Refractoriness,oC179017700.196MPa Load softening starting temperature,oC155015001470Reburn line change rate,%1500oC×2h±0.4Apparent porosity,% ≤1922Compressive strength at room temperature,Mpa ≥807060 Company ProfileFAQQ1 : What's the MOQ.
