Magnesium chrome brick

The fired magnesia-chrome bricks are made of high-quality magnesia and fine ore of chrome ore. The amount of Cr2O3 is adjusted according to different needs. The product has good thermal stability and high temperature performance. Widely used in cement kiln, non-ferrous metal treatment furnace.
The direct combination of magnesia-chromium bricks uses chromium ore with low impurity content and high-quality magnesia as raw materials. After high-pressure forming, it is fired at high temperatures above 1700°C. High temperature performance, strong resistance to slag erosion.
Semi-recombinant magnesium chrome bricks and recombined magnesium chrome bricks, using some or all of the electrosmelted sand (fused synthetic sand) as raw materials, fine ingredients, high pressure forming, ultra-high temperature calcination, good particle bonding degree, high product strength, and stable volume Good performance, widely used in RH, AOD, VOD and other external refining equipment, non-ferrous metal treatment furnace.
