Hot Sale fused chrome zirconium corundum brick in Sunrise Refractory

The fused chrome zirconium corundum brick is also called AZCS brick and adopts a non-shrinkage casting process. The skin and interior of the brick are dark green. The molten brick contains 4.5% shrinkage holes and no connected pores.

 

 

The content of chromium oxide in sintered chrome corundum bricks is generally lower than that in fused chromium corundum bricks.

 

It is also possible to mix the alpha alumina powder and the chrome oxide powder uniformly by a mud casting method, and add a part of the chrome corundum clinker, which is a brick grouting method.

 

The colored glass kiln can be made of AZCS bricks containing Cr2O3 to improve the corrosion resistance of the wall.

 

The corundum main crystal phase is (al2-xcrx)O3. The glass phasor is similar to the ordinary fused AZS brick, and the chemical composition of the glass phase is determined by micro-analysis. A large amount of Cr2O3 is dissolved in the glass, and chromium ions forming a glass structure are identified as Cr2+. That is, cr3+ is reduced to Cr2+ in the melt. This is due to the fact that the melt is in a relatively reduced atmosphere.

At present, the application of chrome corundum bricks has been extensive, mainly used in carbon black furnaces, rolling furnace slides, steel platforms. Has good thermal stability and high temperature creep properties.

 

Sintered chrome corundum brick is widely used in glass kiln lining, fluid hole cover glass brick, glass fiber kiln body and upwind, stained glass kiln with severe corrosion, insulating glass fiber kiln wall, bottom and furnace preheating equipment With the support of the coal-water slurry pressurized gasification furnace, the metallurgical molten pool of the ceramic glaze kiln discharge port and the rotary kiln, zinc smelting furnace.
