Product Description:

Okorder series heat insulation brick

Okorder series thermal insulation brick is an effective, energy saving, low carbon, environmental protection advanced, according to the ASTM standard manufacturing products. Okorder series products have all kinds of materials in the field of metallurgy, industrial furnaces, aluminum, the best Li Ning petrochemical and insulation, electric power and glass ceramics. They can be used as part of an insulation or not to melt. Products have been widely used in the following furnace, achieved satisfactory results.

Application of heat preservation brick

Metallurgical Industry: blast furnace, hot blast furnace, heating furnace, etc..

Petrochemical Industry: ethylene cracking furnace, hydrogen furnace, the main furnace, heating furnace, etc..

Ceramic industry: roller kiln, kiln, etc..

Glass industry: glass furnace regenerator, etc.

Carbon industry: carbon furnace, etc..

Aluminum electrolysis industry: aluminum reduction cell, etc.

Other industries: tunnel kiln, shuttle kiln, etc..

Advantages of heat insulation brick

Low thermal conductivity: many air holes will bring good thermal insulation effect, energy saving.

High crushing strength: high crushing strength, volume stability.

Low heat storage: small heat storage, absorb more heat, energy-saving effect is obvious.

Chundu: High-speed Rail, low content of alkali metal impurities.

Accuracy: the size of the brick machining precision, cutting and grinding the special shape, speed up the brick.
