K26/JM26 Mullite Insulation Brick
1.Light weight brick good for energy conservation 2.Low thermal conductivity and excellent heat resistance 3.Good volume stability at high temperature 4.Low heat storage, high hot compressive strength 5.Resistance to erosion, resistance to abrasion 6.Accurate dimension, designed packaging 7.High alumina, low iron and alkali flux content
Brief Introduction
K/JM26 Insulation Brick is an effective, energy saving, low carbon, environmental protection advanced, according to the ASTM standard manufacturing products. Okorder series products are best Li Ning and insulation in all types of industrial furnaces in the metallurgical field, aluminum, petrochemical, electric power and glass ceramic materials. They can be used as part of the working layer of thermal insulation or non – melting. Products have been widely used in the following furnace, achieved satisfactory results.
By using the K26/JM26 mullite insulation brick, the total weight of the furnace body and walls thickness can be reduced effectively, thermal efficiency and working condition can be improved,energy consumption can be lowered, produtivity and significant economic results can be achieved.
