Chrome zirconium mullite composite brick for rotary kiln

Corundum bricks are mainly used in iron-making blast furnaces and blast furnace hot blast furnaces, refining furnaces outside steel-making furnaces, sliding water heaters, glass melting furnaces and petrochemical industrial furnaces, etc.

The heavy part of the raw materials for the chrome zirconium corundum composite brick is sintered tabular corundum, high-purity chromium oxide, high-purity zircon, and Guangxi white cement.As the main raw material, the light part of the raw material is made of 47 mullite, kyanite, floating beads and coke gemstones as the main raw materials. During molding, a separator is set in the middle of the mold, and heavy materials and light materials are added at both ends. After high pressure molding , finished products made of high temperature sintering.

Chrome corundum brick refers to corundum refractory products containing Cr2O3. At high temperature, Cr2O3 and Al2O3 form a continuous solid solution, so the high temperature performance of chromium corundum products is better than that of pure corundum products. Chromium corundum products are widely used, and the content of Cr2O3 is mostly in the range of 9% to 15%.

Brown corundum refractory brick is made of fused corundum as the main raw material. It is formed by high pressure and fired at high temperature. It has high thermal shock stability, low porosity, low expansion, good resistance to melt vapor and gas erosion, and excellent oxidation resistance. Dimensionally accurate advantages.

Refractory ramming mass (refractory taphole mass) is a kind of Refractory used for lining of blast furnace tapping groove. It is mainly used to protect the blast furnace out of the ditch from high-temperature hot metal and slag erosion and erosion, and has excellent high-temperature resistance and wear resistance. The ramming material for the iron discharge ditch is usually composed of corundum, silicon carbide and carbonaceous material, which has the ability of resisting hot metal and molten slag erosion and scouring, reburning line change small, strong resistance to a variety of oxidation characteristics. The construction of the ramming material for the iron ditch is convenient, easy to dismantle and repair, does not produce harmful gas, and is beneficial to environmental protection.

Corundum refractory castable has the characteristics of high strength and good fluidity, which is convenient for construction. It is mainly used for the parts that are easy to be washed and worn, such as the combustion chamber, separator and flue of circulating fluidized bed boiler.

Corundum self flowing castable is a high-tech product developed according to the theory of solid fluid and combined with the application characteristics of refractory materials, which is the first in China. The corundum self-flowing material can be degassed and leveled without vibration with the help of its own gravity, so as to achieve densification.

Brown Fused Alumia powders are fused wIth premium raw materials and 3500 KVA furnace. It is perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, polishing and sandblasting grit. It has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials. It is also be used as high-class refractory materials. Brown Fused Alumia is offered in macro and micro powder form, in both F and P grades.
