Product Introduction
JM 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 rongsheng JM23/26/28/30 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.
