Lightweight Silica Refractory Bricks High purity Magnesia Fused Spinel Fused Magnesia Spinel for Refractory Bricks
Lightweight Silica Refractory Bricks have the characteristics of low thermal conductivity, high load softening temperature, small residual expansion, and excellent reburning line change performance. Lightweight Silica Refractory Bricks are suitable for industrial furnaces such as coke ovens, hot blast furnaces, glass furnaces and carbon furnaces. Lightweight Silica Refractory Bricks 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 kiln equipment 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 glass furnace.
General Lightweight Silica Refractory Bricks can be divided into two levels: the first grade can be used in the top of the steel rolling heating furnace and the roof of the silicate industrial kiln, and can be directly in contact with the flame; the second grade is used in the general industrial kiln Insulation. Applicable to: industrial furnaces such as coke ovens, hot blast furnaces, glass melting furnaces and carbon calciners. Generally, the bulk density of silicon heat insulation refractory bricks is 0.9-1.1g/cm3, the compressive strength is 2.0-5.9MPa, and the thermal conductivity is 0.35-0.42W/(m·K). It has excellent fire resistance, its softening temperature under load is close to 1620℃ for dense silica bricks, with only a small residual expansion, and its thermal stability is better than dense silica bricks. Therefore, siliceous heat-insulating refractory bricks can be used for a long time under high temperature conditions (1500-1550°C) without contact with molten slag, but Lightweight Silica Refractory Bricks are especially suitable for high-temperature hot-blast furnaces of large blast furnaces. Thermal insulation of silica brick gas.
Advantage:
1, No Shrinkage At High Temperature,Volume Stability
2, It Can Be Used For A Long Time Under High Temperature
3, It Can Shorten Heating Period And Reduce Energy Consumption
4, It Can Extend The Service Life Of Kilns
Application:
Lightweight Silica Refractory Bricks is mainly used for Metallurgy, building materials, chemical industry, petroleum, machinery manufacturing, silicate, power and other industries.
Lightweight Silica Refractory Bricks is widely used for the linings and insulating layers of industry kilns, and the areas without strong erosion and souring action by molten materials at high temperature
