| High Light | Magnesia Based Refractory Gunning Material ，Refractory gunning mass ，Back Kilneye Refractory Gunning Material | ||
Very good corrosion resistance Magnesia based refractory gunning material used in the back kilneye
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.
Application
Low cement castable is used in the back kilneye, wicket cover and back of cooling machine of cement rotary kiln and other thermal equipment with good performance and long service life.
