Abstract
Utilization of waste refractory material has attracted much attention due to the development of metallurgical industry and the requirements of environmental protection. This article mainly researched on the Al2O3-ZrO2-C sliding nozzle that prepared using its recovery refractory and some other new materials. The addition of the recovery material leads to the formation of ZrO2compound. The performance of the sliding nozzle is enhanced by controlling its microstructure, including the improvement of strength under cold and high temperature, and increase in slag resistance.
