Alumina Magnesia Gunning Castable Steel Ladle Castable Material
Steel Ladle Castable
steel ladle mainly suffers high temperature steel liquid (about 1650℃) thermal impaction, mechanical abrasion, molten slag and steel liquid chemical corrosion, especially damage to ladle bottom is the severest. For middle size and large scale ladles, corundum magnesia castable and corundum alumina magnesia spinel castable are usually used as ladle wall and bottom working lining. Slag line zone is usually built by magnesia carbon bricks. Gunning castable use in steel ladle includes alumina magnesia gunning castable, magnesia gunning castable, magnesia spinel gunning castable and so on.
Steel ladle castable categories
1. Al2O3-MgO-C Castable Al2O3-MgO-C castable can produce magnesia alumina spinel and significantly enhance corrosion resistance and spall resistance of refractory material, greatly prolong the service life of steel ladle.
2. Alumina Magnesia Castable
Alumina magnesia castable are gradually used in steel ladle, the lining service life can reach to 60 times or more, refractory material consumption is reduced by 60%~80%.
3. Alumina Magnesia Spinel Castable
Bauxite based alumina magnesia spinel castable contains certain ratio of magnesia alumina spinel, which makes castable’s corrosion resistance and spall resistance ability improved greatly, the performance is better than water
