JM Insulation Bricks
DESCRIPTION
CT firebricks are made from high-purity refractory clays, temperature of use ranging from 1100 oC to 1700 oC, each grade is formulated to meet specific thermal and physical requirements.
With graduated additions of alumina for higher temperature products
Carefully grade d organic filler
The organic filler burns out during manufacture to give a uniform, control pore structure.
FEATURES
Low density
High purity
Low thermal conductivity
Excellent thermal shock resistance
SPECIFICATIONS
JM insulating brick, using high pure mullite as raw material, is made by adding alumina powder
JM insulating brick, using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature.
JM insulating brick is the new energy saving material for insulation.
APPLICATIONS
Glass industries iron & steel industries
Ceramics industries non-ferrous metals industries
Electrolytic Aluminum industries power generation industries
Heat surface fireproof lining other fire-proof back lining
