Product description
Insulation bricks for furnace is to point to the finalize the design of refractory brick products for porous structure inside, bulky density is small, porosity is high, sex of heat insulation high temperature is excellent, also can call light firebrick or brick of light heat preservation. Use raw material according to material material is different, divide for a variety of, if be made with clay, silicon qualitative and high alumina etc. raw material is called light clay brick, light silicon brick and light high alumina brick.
Advantages of insulation bricks for furnace:
Low thermal conductivity, low hot melt, low impurity content, fire resistance and temperature resistance, good thermal shock stability, significant energy saving effect,etc.
Because insulation bricks for furnace with smaller bulk density whose strength is not as strong as heavy weight fire bricks, when delivering, CH Refractories will package insulating firebricks with special packages to protect insulating clay bricks from damage.
Application of insulation bricks for furnace
◆Glass industries iron & steel industries
◆Ceramics industries non-ferrous metals industries
◆Heat surface fireproof lining other fire-proof back lining
◆Electrolytic Aluminum industries power generation industries
