China 2021 China New Design Acid Refractory Bricks - RS Refractory High Chrome Bricks – Rongsheng factory and manufacturers | Rongsheng Detail:

High chrome bricks is made of 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 high chrome refractory 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%.

Properties of High Chrome Bricks

  • High strength,
  • Corrosion resistance,
  • Erosion resistance,
  • Excellent slag resistance,
  • Good thermal shock stability.

Composition of High Chrome Bricks

High chrome bricks are mainly consist of Cr2O3, monoclinic zirconia and alumina powder. Therefore, the performance of high chromebricks is closely related to the performance of these substances. High chrome fire brick contains chromium hemitrioxide 30%, and high chrome brick is featured with acid and alkali slags resistance, and are mainly used in the isolation layer, and nonferrous smelting furnaces, etc.

High Chrome Bricks Manufacturing Process

High chrome refractory brick is 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. High chrome bricks are widely used in the cement kiln and nonferrous metallurgical furnace etc.
