Magnesia Alumina Brick.Magnesia Alumina Spinel Brick
Magnesia alumina bricks and magnesia alumina spinel bricks are manufactured by using various grades of magnesite,bauxite grog and magnesia alumina spinel clinkers as raw materials under high temperature burning,which have higher refractoriness under load and better thermal shock resistance to basic melting slag.They are mainly applied to the top of steel making electric furnaces,high temperature tunnel kilns,lime kilns,checkers of regenerators of glass kilns,large—scale cement rota ry kilns and non ITOUS metal smelting furnaces,etc.
