It is suitable for the insulation layer of boiler furnace wall and the lining which is not affected by slag and aggressive gas. Insulation refractory brick is an insulation material made of organic matter as a burn-off agent to increase the porosity of refractory material. It has high porosity, small bulk density, good heat insulation effect, high mechanical strength, small thermal conductivity and long service life. The advantages are the energy-saving insulation refractories that are indispensable for the construction of various industrial furnaces.
Clay lightweight refractory bricks are divided into: NG1.3, NG1.2, NG1.1, NG1.0, NG0.8, NG0.6, NG0.4. Among them, N and G respectively represent clay and heat insulation.
