The service performance of corundum castable can be improved by mixing with the AMC composite which features good slag resistance and thermal shock resistance of CA6 and MA.Besides,the AMC composite,as a new product of resource recycling,can significantly reduce the production cost of refractory materials.According to the experimental results,adding 30%AMC composite into corundum castables can generate relatively ideal experimental data.Its application to the ladle seat bricks has achieved good results,not only reducing the production cost,but also effectively prolonging the service life of ladle seat bricks.
