Product Description
Burnt magnesia chrome bricks are made from high quality magnesia and chrome concentrate. Chrome content can be adjusted accroding to different requirements. The bricks have good thermal stability and high temperature performance. They are widely used in cement kilns and non -ferrous metal metallurgical furnaces. The magnesia bricks can be directly bonded, semi-rebonded and rebonded. By the best proporioning, high pressure moulding, ultra high temperature firing, the bricks obtain good grain bonding, high strength and good volume stability.
