Sintered Silica Refractory Material Brick

1. Product Name：Sintered Silica Series2. Item Code：A24013. Product Introduction： Silica series，a kind of acid refractory material, is mainly consisted of scale quartz, calcite, a small amount of residual quartz and vitreous phase. The content of silica is generally above 94% and true density is 2.35g/cm3. It owns resistance of acid slag erosion and good strength in high temperature conditions. Its refractoriness under load is 1620 ~ 1670℃ and it is capable of long-term working under high temperature without deformation. In addition, thermal shock stability of the series is relatively low. (Heat exchange in water is 1~4 times.) 4. ApplicationIt is mainly used in top spaces of glass furnace (crown, end wall, breast wall, regenerator section), as well as in metallurgical application.Generally speaking, the performance and index of silicon series applied to glass and metallurgical fields are obviously different.  5. Characteristics Silicon series belongs to acid refractory which has good acid corrosion resistance, good thermal conductivity and high refractoriness under load. Besides, the price of the series is relatively low.6. Physical and Chemical IndicatorsItem CodeGZ-96GZ-95GZ-94BG-96ABG-96BBG-95ABG-95BChemical CompositionSiO2≥%96959496969595Fe2O3≤1.01.21.40.81.01.21.2Melt Index (Al2O3+2R2O) unit Weight＜20kgunit Weight≥20kg≤0.50.6--0.70.7--RUL 0.2MPa≥℃166016501640(Cementing Silica 1620)1680167016601650AP≤%22(24)CCSunit Weight＜20kgunit Weight≥20kg≥MPa35(30)30(25)True Density≤g/cm32.342.352.342.35Application FieldsMetallurgical IndustryGlass Furnace IndustryData in brackets are indicators of handmade bricks.
