Refractory Brick for sale, an excellent kiln refractory material, is briefly called fire brick that has certain shapes and sizes. Refractory brick includes different types of burnt brick, unburned brick, fused cast brick, and refractory insulating brick according to different manufacturing processes. Refractory bricks can be used as high-temperature building and structure materials for kiln and all kinds of heating equipment to resist all kinds of physical chemistry changes and mechanical action. |

| Refractory brick contains about 50~80% aluminium oxide content and less silica content. Refractory Brick for Sale is a kind of inorganic nonmetallic materials with more than 1580 ℃ refractoriness. Refractoriness means the centigrade degree for high temperature that cone-shaped body sample of refractory materials can resist and will not be soft and molten at the situation without loading. Refractory materials are widely used in many industrial fields such as metallurgy, chemical engineering, petroleum, machine manufacturing and power industry. And refractory materials are mostly used in metallurgical industry High refractoriness Thermal stability, Volume stability, High-temperature chemical stability, High-temperature structure strength, Bulk density and apparent porosity, Thermal conductivity, heat capacity, and thermal expansio. |
