MgO-AL2O3 Refractories Mag-Al bricks are manufactured by qualified MgO≥91% or MgO≥94.5% magnesite and qualified bauxite. In the matrix there are both of high temperature phase of periclase, and the spinel, another high temperature phase. They have, therefore, a good performance under high temperature and thermal shock resistance. They are widely used in open hearth furnace of steel-making, non-ferrous metallurgical furnaces, and so on. If some amount of chrome put in, the spinel becomes better, which is the best material used in non-ferrous metallurgical furnace and the proof of open hearth furnace of steel-making .The matrix of the spinel brick made from the synthetic Mag-Al spinel grain is in good structure that makes the fired crystal composed in good density and better thermal shock resistance. In the meantime, the chrome pollution is better controlled. The brick is a new kind of refractories widely used in the cement and lime kilns. SortMgO-AL2O3Corundum Bricks BrandIndexQML
