Magnesia Chrome Brick Introduction
Magnesia chrome bricks are made of magnesia oxide and chromium oxide and the main mineral constituent is periclase and spinel. The purity of magnesia raw materials should be as high as possible, the chemical composition requirement of chromite is: Cr2O3:30 – 45%, CaO = 1 ~ 1.5%. Magnesia chrome refractory bricks with the characteristics of high refractoriness, high temperature strength, strong corrosion resistance to alkaline slag, good thermal stability and a certain adaptability to acid residue.
