Ultra-light Insulating refractory brick

PRODUCT DETAILS


SK series of Ultra-light Insulating refractory brick

SK series brick is world leading technology in insulating refractory field. It has the advantages of low carbon, environmental, ultra light, energy saving and low consumption. It has nanometer grade micropore structure. It can be widely used in all kinds of high temperature furnace of metallurgy, petrochemical industry, building materials, nonferrous industry.

The actual performance prove that the furnace body can reduce by 30% thickness, 50% lining weight, 40% fuel by using SK series brick. It was the most economic and effective product among the similar materials.

Main characteristics:
1, There is no Carbide out using under high temperature, it was clean and stable, and has high strength, good volume stability and thermal shock resistance;
2, It has uniform structure, light weight, good thermal conductivity and insulation property, that can reduce the heat loss and save energy;
3, It can be used in all kinds of special requirement industrial furnace, and it has no effect on the internal condition, so the quality of final products can be improved;
4, Easy and fast installation, good quality of installation and lower labor intensity requirement;
5, Patented products and long lifetime.
