Product Description of Chrome Corundum Bricks                                                                       

Chrome corundum brick is alumina - chrome oxide as the main raw material production of high-performance chrome corundum brick, has the characteristics of high refractoriness, great strength, good thermal shock stability, strong ability to resist erosion. In use, the scouring resistance, wear resistance, resistance to flake structure, has been in metallurgy, glass, carbon black and the petrochemical industry, has obtained the good using effect. Chromium corundum brick raw material is used by the ratio of alumina and chromium oxide according to certain proportion, go through high temperature melting synthesis of a solid solution. Using special refractory production technology made of refractory brick, can improve internal quality of the product, improve the high temperature performance of products.

Characters and Applications of Chrome Corundum Bricks                   

1. The refractory properties of chrome corundum brick

In high purity corundum material add Cr2O3, no matter how much the amount, not only will not reduce the fire performance of materials,can make refractory performance of material improved.

2. The strength of chrome corundum brick

Compressive strength of high purity corundum brick at room temperature is 70 ~ 100 MPa commonly, room temperature compressive strength of high performance chromium corundum brick is generally larger 150 MPa, the intensity is significantly higher than the corundum brick. This is because the products in the process of burning, between particles and fine powder, between powder and powder are formed Al2O3 - Cr2O3 solid solution, calcium solid solution like bridge connect fine powder with particles together, make the strength of the material is greatly increased.

3. Thermal shock resistance

Add Cr2O3 in corundum, when Cr2O3 content is 10% ~ 66%, material of thermal shock resistance decreased with increasing content of Cr2O3, namely the Cr2O3 content low chrome corundum brick, the thermal shock stability is better than Cr2O3 content high chrome corundum brick.

4. Slagerosion resistance ability

Cr2O3or containing Cr2O3 of refractory material has the good resistance toslag, non-ferrous metallurgical slag, coal gasification furnace, oil gasfurnace slag and all kinds of glass melt dissolution ability. Cr2O3 meltor Cr2O3 reaction with slag generated liquid viscosity is larger than other lowmelt viscosity

 For use in the iron and steel industry, chrome corundum brick material is above double longer than service life extended of corundum material, such as ladle air brick, etc. For use in nonferrous smelting industry, the wear resistance and erosion resistance of chrome corundum brick is superior to other bricks.

Company Profile                                                                                             

Zhengzhou Huachen Refractory Co.,ltd (HCR )was established in 2003, headquartered in Zhengzhou city, Henan Province, China.

HCR is specialized in manufacturing Refractory Bricks/Blocks, especially Fused Cast Blocks/Bricks, Magnesite Series Bricks/Blocks, and other various kinds of refractory materials. We currently have two plants, one produces the fused cast blocks, such as AZS 33#.36#,41#; the other plant produces the MgO2 series bricks and Al2O3 series bricks, such as Magnesite brick, Magnesite-chrome brick, Mg-Al spinel brick, high alumina brick and fire clay bricks .

HCR expands its overseas markets quite repaidly through these years' hard-work, up to the present, we have exported our refractory bricks/blocks to America, Australia, Vietnam, Russia, Kazakhstan,Turkey etc., HORN , Ocean Glass, RHI, Calderys are some of our working partners. We always believe that our high quality products, competitive prices and excellent after-sales services will fulfill any requirements from you.
