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.
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.
Feature
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.
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.

Application
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.
Packing
1.Strong packing will protect the goods from any possible damage during transit.
2.Solid packing and overall stuffing can prevent the cases from vibration and jarring.
3.We must take necessary precaution that the packing can protect goods from pilferage or rain.
4.We can confirm that we take every possible precaution to ensure that our products reach our customers all over the world in prime conditon.
