Application of High Chrome Bricks

Application of Rongsheng high chromium bricks. Since chromium oxide is a heavy metal oxide, its melting point is 2350°C, its true density is 5.23 g/cm3, and its Mohs hardness is 7~8. Linear expansion coefficient (/℃) 9.0x 10~6, thermal conductivity 2.6~2.8 W/(m·K). Moreover, chromium oxide is a neutral refractory material, so it is also a good material that resists acid and alkali erosion. Chromium oxide is the best material to resist erosion by coal slag and glass liquid, so it has achieved remarkable results when used in large-scale ammonia gasification furnaces with coal-water slurry and large-scale glass kilns and glass fiber kilns.
