High fired magnesite chrome refractory bricks for glass furnace
Magnesium chrome brick magnesia (MgO) and chromium oxide (Cr2O3) as the main ingredient, periclase and spinel as the main mineral components of refractory products. Such brick high refractoriness, high temperature strength, resistance to basic slag erosion resistance, excellent thermal stability, acidic slag also has some adaptability. The main raw material to manufacture magnesium chrome brick is sintered magnesia and chromite. Purity magnesia raw material to be as high as possible, the requirements of the chemical composition of chromite is: Cr2O3: 30 ~ 45%, CaO1.0 ~ 1.5%.

Fused re-bonded magnesia chrome brick:
The magnesia chrome refractory for RH refining device developed by the Company has the characteristics of high purity.high fire resistance and good thermal stability.It’s applicable to large.medium and silicon steel RH refining devices, This project is tested on the RH silicon steel device in Wuhan lron & Steel.and the tested service life was increased by 20%.
The burnt high fired magnesite chrome bricks are made out of high-quality magnesite and chrome ore fine charge mixture.According to different demands,adjust the content of Cr2O3,The product thermal stability and high-temperature performance are satisfactory,It’s widely used in the cement kiln and nonferrous metallurgical furnace etc.
1.Direct bonding high fired magnesite chrome bricks choose the raw materials of chrome ore with low impurity content and magnesite with high quality and high purity,and adopt the high-pressure forming and over 1700℃ high-temperature sintering.The high-temperature performance is satisfactory,and the metallurgical slag corrosion resistance is strong.It can resist the corrosion of cement clinker,It’s widely applied in the electric furnace lining for steel making,nonferrous metallurgical furnace and cement rotary kiln etc.
2.The semi-rebonded high fired magnesite chrome bricks and rebonded high fired magnesite chrome bricks all or partially use the fused sand(fused synthetic clinker)as the raw materials,choose the fine charge mixture and adopt the high-pressure forming and super-high-temperature burning.The products have good particle bonding degree,high product strength and good volume stability.They are widely used in the secondary refining devices like RH,VOD and AOD,and nonferrous metallurgical furnace as well.
