摘　　要：介绍了宝钢干熄炉应用耐磨预制块的研究成果。耐磨预制块具有抗剥落、热震稳定性好、高强耐磨等优良性能。宝钢实际应用结果表明,在干熄炉相同部位使用耐磨预制块替代传统烧成莫来石砖,耐磨预制块的磨损速率较莫来石砖下降70%以上,大幅提高了干熄炉冷却段耐火材料的使用寿命,降低了检修频率以及耐火材料的消耗。The development achievement of wear-resistant pre-fabricated block which has been used on CDQ chamber of Baosteel was introduced.The wear-resistant pre-fabricated block has the excellent performance of falling resistance,good thermal shock stability,high strength and wear resistance.The result of actual application at Baosteel showed that the conventional burnt mullite brick used at the same location of CDQ chamber was replaced by the wear-resistant pre-fabricated block,the wear rate of wear-resistant pre-fabricated block was reduced by 70% or more,the service life of refractory used at the cooling zone of CDQ chamber can be substantially increased,and the repair frequency and consumption of refractory can be reduced.
