1. Intruduction XINDI Insulating Firebrick(IFB)with light weight, has high mini-porosity arranged in average, keep furnace wall low radiation and depress the charges of fuels. Light weight for IFB means the lowest thermal storage,it's quicker to heat and cool, and permit rapid cycle work. They are used for 9001650, you can choose the most economical products according to service temperature. XINDI Light Weight Insulating Firebrick is in accordance with ISO9001 Standard. 2. Typical Application 1) Lining of high-temperature kilns of industrial ceramics, industrial furnaces under 1650 of petrochemical, metallurgy and machinery industries 2) Lining of hot-surface of industrial furnaces as carbon furnace, cracking furnace, heating furnace for oil refining, roller kiln, tunnel kiln. 3) Back lining insulating layer of industrial furnace as glass tank kiln. 4) Deoxidizing atmosphere furnace. 3. Series of Firebrick for BC Series Products have excellent properties as light weight, low ferrous, low shrinkage after heavy firing, atmosphere erosion resistant,low thermal conductivity, thermal shock resistance, thermal performance and heavy firing line in small, low impurity content, mullite Jing Shi content, appearance size accurate, and easy construction and so on. Note: We can also produce according to your designated special shape so long as the quantity is substantal
