теплоизоляция кирпич (НГ серии)

1. IntruductionXINDI 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 NG Series Products A unique manufacturing process is cool, good thermal shock resistance characteristics, the use of the wall can reduce the heat capacity and improve the thermal efficiency furnace.
