The Description:
Silicon bricks are used more in glass melting kilns, and the main component is silicon dioxide (SiO2). The silica brick used in glass melting kiln requires a SiO2 content of more than 94%, a high use temperature of about 1600~1650ºC, and a density of 1.8~1.95g/cm3. The apparent porosity should be less than 22%, and the larger the porosity, the worse the quality of silicon brick. Most of the appearance of the silicon brick is white crystal, the microscopic composition of crystalline quartz crystals, because the silicon brick at high temperature to occur crystallization transformation, volume expansion, especially in 180 ~ 270 ° C and 573 ° C or so, crystallization transformation is more intense, so in the kiln and cold repair process to adapt to the silicon brick crystallization transformation and take appropriate measures such as tension strip. The silicon brick masonry should have expansion joints.
Features of Glass Furnace Silica Brick SiO2 Refractory Brick
(1)The high temperature volume is stable, and the furnace body will not change due to temperature fluctuations. Due to the high softening temperature of the silicon brick under load and the small creep rate, the furnace body can be maintained at 1600°C and the structure is stable.
(2)No pollution to glass liquid. The main component of silicon brick is SiO2, and if there is a drop or surface melt drop when in use, it does not affect the quality of the glass liquid.
