JM insulation bricks has JM23 insulation bricks, JM26insulation bricks, JM28insulation bricks.

JM insulation bricks FEATURES:

1.Low thermal conductivity:Gives good thermal insulation, enabling the use of thinwalled constructions.

2.Low heat storage:Due to their light weight and low thermal conductivity, JM bricks absorb minimal heat, giving significant energy savings in cyclically-operated kilns.

3.High hot compressive strength

JM insulation bricks Application

JM insulation refractory bricks are widely used for heat-insulating purpose in many kinds of industrial furnace, electric furnace and metallurgical stove, Cracking furnace in petroleum, Hot blast furnace in metallurgy,Ceramic roller kiln, tunnel kiln, shuttle kiln for electrical porcelain, Pot furnace for glass industry, Inner lining of kinds of electrial furnaces and high temperature equipment.
