Product descriptions
Insulating silica bricks generally use crystalline raw materials sand as raw materials, and the mineral composition is: phosphorite 78% to 86%, cristobalite 13% to 15%, and quartz 4% to 7%. Add combustible materials to the ingredients, such as coke, sawdust, anthracite, carbonized rice husk, or use gas foaming to form a porous structure. Insulating silica brick Price are heat-insulating silicon refractory products with a SiO2 content of more than 90% and a bulk density of less than 1.2. The refractoriness and softening temperature under load are not much different from ordinary silica bricks with the same composition. However, due to the many pores, the compressive strength, slag resistance, and corrosion resistance are not as good as ordinary silica bricks, but the thermal shock resistance has been improved. It is similar to the production process of ordinary silica bricks. Some mineralizers (CaO, Fe2O3) are added to the ingredients to promote the conversion of quartz, and pulp waste liquid is used as a binder to make the bricks have a certain strength. When using coke or anthracite as combustible additives, because the ash will be brought into Fe2O3 and Al2O3, there is no need to add iron scales in the ingredients. When the siliceous Insulating silica bricks are fired, a strong oxidizing flame should be maintained before 1200°C to make the additions burn out completely.
Insulating silica bricks have the characteristics of low thermal conductivity, high load softening temperature, small residual expansion, and excellent reburning line change performance. They are suitable for industrial furnaces such as coke ovens, hot blast furnaces, glass furnaces and carbon furnaces.
It is mainly used for the heat insulation layer and working layer of thermal equipment, and can be used for the heat insulation layer of various high temperature stove under high temperature conditions (≤1500℃) without contact with molten slag. This product is suitable for the heat insulation material of the silica brick lining of the high temperature hot blast stove of the large blast furnace and the heat insulation of the silica brick masonry of the furnace.
