Manufacturing Process Of Silica Bricks For Sale

  • Silica bricks for sale adopts SiO2 rock as the raw materials and require less than 2% Al2O3, TiO2 and alkali metal oxide content. Its manufacturing process is similar to ceramics.
  • Silica refractory brick properties have a close relation with crystal type transform of SiO2 in the process. True specific gravity is an important quality index, which should below 2.38. Less true specific gravity means the more quantity of tridymite and cristobalite and less quantity of residual quartz, which as a result of low residual linear expansion and low reduction in strength.
  • There are more SiO2 content in silica as the raw materials in the manufacturing process of Silica Bricks, there are higher refractoriness. The most harmful impurities are Al2O3, K2O, Na2O and etc. which badly reduce the products’ refractoriness.
  • Choose the silica with over 96% content mixed mineralizer such as iron scrap and lime milk, and binding agent like molasses and lignosulfite through process of mulling, molding, drying and sintering and etc to manufacture Silica Bricks.
