HT-SIL162/168 series material is mainly composed of quartz sand base, added with a certain proportion of high temperature sintering agent; after sintering at high temperature, the structure is dense and resistant to penetration and erosion of metal liquid.
HT-RAM401/426CR series material is mainly composed of quartz sand base, added with a certain proportion of fused quartz, whose volume is more stable under high temperature reaction; the particle size distribution is strictly controlled, so that the expected service life of the furnace lining is increased, and the use of material is expanded. It has excellent thermal shock resistance and low permeability.
