With the main raw materials of high quality bauxite,corundum,fused magnesia and alumina magnesia spinel,adding a proper amount of additives the performance of ladle repair material can be improved by adjusting the particle size distribution and composition.The improved repair material has been used in  a 300 t ladle of a steel plant,which is proved to have good plasticity and adhesiveness; excellent construction and performance; less rebound and adhesion rate is more than 95%;after being applied once and used for one cycle (30~35 furnaces),the repair material on the east and west sides of the ladle still exist.
