The castables for ladle nozzle were developed using brown corundum as the main raw material and the right amounts of complex additives. The influence of several additives on the properties such as strength and permanent linear change of the samples was studied. The results showed that applying complex additives improved the strength and the volume stability of the castables greatly. The campaign of the castables for ladle nozzle has increased from about 40 heats to 70 heats.
