What are the advantages of sunrise refractory chrome corundum brick?

Thermal shock stability of chrome corundum brick.

 

According to the data, Cr2O3 is added to corundum. When the content of Cr2O3 is 10%~66%, the thermal shock stability of the material decreases with the increase of Cr2O3 content. The chrome corundum brick with low Cr2O3 content has better thermal shock stability. Chromium corundum brick with high Cr2O3 content. The high-performance chrome corundum brick Cr2O3 content promoted and applied by our factory is between 12% and 20%, and its thermal shock stability is improved compared with corundum brick: especially the chrome corundum brick produced by adding a small amount of phase change additive. Thermal shock stability is better.

Slag corrosion resistance of chrome corundum brick.

 

Cr2O3 or Cr2O3-containing refractories have good corrosion resistance to steel slag, colored smelting slag, coal gasifier slag, oil gasification slag and various glass melts. The viscosity of the liquid phase formed by the reaction of Cr2O3 melt or Cr2O3 with slag is greater than that of other low-melting materials, which prevents the slag from penetrating into the interior of the brick body along the capillary pores, avoiding the formation of metamorphic layers and causing structural spalling.

 

The effect of chrome corundum brick produced by our company in the steel industry is more than double the service life of corundum material, such as ladle ventilated brick: in the non-ferrous smelting industry, the wear resistance and corrosion resistance of chrome corundum brick are obvious. Better than other bricks: In the carbon black industry, chrome corundum bricks are twice as long as corundum bricks used under the same conditions.
