摘要: 研究了不同水韧条件下ZGMn13Cr2钢的脱碳行为,分析了实际脱碳深度与理论计算之间的关系,并对传统的计算模型进行了修正。结果表明,水韧处理加热温度越高,保温时间越长,脱碳越严重。当加热温度为1000 ℃时,实际脱碳深度与理论脱碳深度相似;加热温度为1050 ℃和1100 ℃时,由于氧化反应的加剧以及碳化物的作用,实际脱碳深度大于理论脱碳深度,传统的计算模型不再适用,采用修正的计算模型能对ZGMn13Cr2钢水韧处理中的脱碳深度起到一定的预测作用。

Abstract: Decarburization behavior of ZGMn13Cr2 steel under different water toughening conditions was studied. The relationship between actual decarburization depth and theoretical calculation was analyzed, and the traditional calculation model was modified. The results show that the higher the heat temperature for water toughening and the longer the holding time, the severer the decarburization is. When the heat temperature is 1000 ℃, the actual decarburization depth is similar to the theoretical decarburization depth; when the heat temperature is 1050 ℃ and 1100 ℃, the actual decarburization depth is larger than the theoretical decarburization depth due to the intensification of oxidation reaction and the effect of carbides, so the traditional calculation model is no longer applicable. The modified calculation model can play a certain role in measuring the decarburization depth of ZGMn13Cr2 steel in water toughening treatment.

Key words: ZGMn13Cr2 steel, water toughening treatment, decarburization, computational model
