ZHENJIN REFRACTORIES founded in 1985. It is a manufacturing enterprise integrating research and development, productions, sales, international trade and technical services. Refractory products and services for cement, lime, non-ferrous, glass, building materials and metallurgical industries.
Magnesia-chrome bricks are generally produced from sintered magnesia and refractory-grade chrome ore. The refractory grains are bonded with silicate. The domestically referred to as magnesia-chrome bricks generally refer to fired ordinary magnesia-chrome bricks, referred to as magnesia-chrome bricks. Chrome tiles.
Magnesia-chrome bricks are refractory products with magnesium oxide (MgO) and chromium oxide (Cr2O3) as the main components, and periclase and spinel as the main mineral components. This type of brick has high refractoriness, high temperature strength, strong corrosion resistance to alkaline slag, excellent thermal stability, and certain adaptability to acid slag. The main raw materials for making magnesia-chrome bricks are sintered magnesia and chromite.
The refractoriness of magnesia-chrome bricks is greater than 2000°C, and the load softening temperature is generally above 1550°C. It has good volume stability at high temperatures, and its resistance to rapid cooling and heat is stronger than that of magnesia bricks.
