The method applies to prolong the life of ladle refractory castable in our country

Extended service life, can save money and bring benefits. Since the conditions of use of extremely harsh refining ladle slag line site and cause serious erosion of the containment wall parts ahead of

refractory castable become so damaged the main reason for its life. Quality of life of refractory castable ladle also plays a decisive role.

Ladle castable ladle development to improve life, to overcome the shortcomings of the brick type play a good effect. The current development has a water glass ladle castable

combination of aluminum and magnesium, aluminum - spinel castable, but with the development of the outer casting and refining technology, the former has been unable to meet the current development of many steel smelting technology needs.

In industrialized countries, the popular use of aluminum - spinel castable. Although this material long life, but at the tabular alumina, alumina and industrial grade synthetic magnesia spinel, alumina cement and other raw materials, the price is expensive. Most of our current domestic economic strength of steel without the use of expensive high-end ladle castable, however, China has abundant bauxite resources and using both synthetic alumina spinel raw materials, these materials are developed ladle castable suitable for China.
