Product description of insulation brick JM30
JM30 mullite insulating bricks are a good refractory raw material, category in which aluminum silicates are produced at high temperatures. Mullite allows the production of various types of intermediate insulating bricks, which have already been successfully used in various industrial sectors.
Features of insulation brick JM30
The advantages of JM30 mullite insulation bricks are: high purity, low impurity content, high temperature resistance, direct contact with flames, resistance to all kinds of atmospheric corrosion, low thermal conductivity, low thermal flow, high resistance and good resistance to thermal earthquakes, high dimensional accuracy and cutting ability.
Application of insulation brick JM30
JM30 mullite insulation bricks are mainly used in the dome of a thermal furnace, hearths and substrates of a blast furnace, heat storage premises in a glass melting furnace, ceramic agglomeration furnace and coating of an oil cracking system.
