Chrome Corundum Bricks - Xinhongji Refractory

 Chrome corundum bricks are a type of corundum refractory product that contains Cr2O3. It is made by using α-Al2O3 as the main raw material and adding an appropriate amount of chromium oxide powder and chromium corundum clinker fine powder. The bricks are then sintered at a temperature of 1700℃.


The most widely used chromium corundum products have a Cr2O3 content of 9%~15%, and the main mineral composition is α-Al2O3• Cr2O3 spinel phase. The chromium oxide content in chrome refractory brick ranges from 1% to 30%. There are two types: fused cast chromium corundum bricks and sintered chromium corundum bricks.

Comprehensive Display of High Alumina Bricks - Xinhongji Refractory

图片
High alumina bricks are made from bauxite or kaolinitic clays. The definition of high alumina bricks contains between 50 and 87.5 percent alumina. They are much harder and tougher than fireclay refractories at high temperatures and in basic environments. In addition, high-alumina refractory bricks exhibit better volume stability and abrasion resistance. The high alumina bricks are mainly used in masonry in blast furnaces, hot blast furnaces, electric furnace roofs, blast furnaces, reflecting furnaces, and lining of rotary kilns. In addition, high alumina brick is widely used in open hearth furnace lattice brick, plugs used in casting systems, nozzle brick, etc. However the price of high alumina brick is higher than the clay brick, so we do not need high alumina brick when the clay brick can satisfy the demand. 🔥 Hot sale! high alumina bricks for sale in stock 📣 Contact now: sales@hongjirefractory.com ☎️ Tel/Whatsapp/Wechat: +86-17026790777 🔗 https://www.hongjirefractory.com/high-al
