Silica Insulating Lightweight Refractory Bricks for High Refractoriness in Coke Ovens

High Refractory Under Load Lightweight Silica Insulation Bricks for Coke Oven

High Refractory Under Load Lightweight Silica Insulation Bricks for Coke Oven are produced with silica through adding inflammable substances such as coke, anthracite coal, sawdust, and carbonized rice husk, or foaming agents to form porous structure. Generally add 35-45% anthracite coal or 30% coke as inflammable substances. Since there are Fe2O3 and Al2O3 in the ash of coke and anthracite coal, there is no need to add iron scales. High Refractory Under Load Lightweight Silica Insulation Brick's main mineral composition includes 78%~86% tridymite, 13%~15% cristobalite and 4%~7% quartz. High Refractory Under Load Lightweight Silica Insulation Bricks for Coke Oven cold crushing strength is 2.0-5.9MPa, thermal conductivity is 0.35-0.42W/(m•K) and density is 0.6-1.2g/cm3.
