With the rapid development of industrial development, lightweight thermal insulation materials have gradually replaced refractory bricks in high temperature kiln furnaces and become a new favorite for kiln energy conservation and environmental protection.
We can choose light weight insulation material with different specification according to furnace temperature and environment. Choose different material as inner lining can reduce furnace wall thickness and furnace weight and accelerate heating rate of furnace. The light weight high temperature insulation material not only can be used as the furnace lining in the kiln, but also can be used as the filling ,sealing and heat insulation material of the high temperature kiln.
Current lightweight thermal insulation material includes silica, clay, high aluminum, corundum and mullite stone, etc. They are applicable to all kinds of industrial furnaces in the general conditions of use (No direct contact with molten metal or slag, no severe mechanical impact, wear, no severe thermal shock, no chemical reaction, no erosion, etc.), can be used to build furnace lining which has direct contact with the flame or intermediate insulating lining.For example, the belt type sintering machine in metallurgical industry, pellet roaster, heating furnace, heat treatment furnace, aluminum electrolyzer, aluminum melting furnace, zinc smelting furnace and rectification equipment;Carbon calcining kiln, ceramic, refractory, building materials products calcining kiln; Various heating furnace, catalytic cracking unit in petrochemical industry, converting furnace of first and second stage of synthetic ammonia equipment, waste heat boiler and converter furnace; Garbage incinerators and resistors for various purposes, etc.
