Product Description
Specifications
magnesite-chrome brick1.Magnesite chrome brick of alkaline slag erosion resistance is strong,
2. good thermal shock resistant
Fireproof brick
Product usages
Used for building steel furnace, furnace refining furnace, non-ferrous metal smelting furnace, cement kiln, glass kiln, etc.
Production process
Production technology of calcined magnesite chrome brick and magnesite chrome bricks in line. In order to eliminate
the bricks in burning process because of MgO style and Cr2O3, Al2O3, or directly combined magnesite chrome
brick. The main raw material of manufacturing magnesite chrome brick is sintered magnesite and chromite. Magnesia raw material purity as high as possible, chromite
chemical composition requirement is: the Cr2O3:30 ~ 45%, CaO: 1.0 ~ 1.5% or less.
Classification
Brick according to the physical and chemical indicators divided into MGe - 20, MGe - 16, MGe - 12, MGe - 8 four grades
Refractory temperature: 1580 ~ 1770 °C (°C)
