摘　　要：分析了 Ｑ２３５ 钢和１０ 钢制耐火砖成型模板过早失效的形式和原因。采用２０ Ｃｒ Ｍｏ 钢代之制作模板，并适当降低渗碳温度，可实现高浓度渗碳。生产试验表明，２０ Ｃｒ Ｍｏ 钢制模板的使用寿命是 Ｑ２３５ 钢和１０ 钢制模板的３～４ 倍。In this paper the premature faiture models and reason of firebrick dies of Q235 steel and 10 steel are analysed.The dies made of 20CrMo steel substituting for Q235 steel and 10 steel,and falling the temperature of carburizing properly can achieve high carbon concentration carburizing.Productive tests in a factory show that the service life of firebrick dies made of 20CrMo steel is 3 times more than that of Q235 steel and 10 steel.
