摘要: 表面脱碳是热轧板材生产的重要问题之一。在实验室条件下，研究50CrV4钢在650～1 100℃温度范围内的脱碳特性及其对淬硬性的影响。根据扩散理论对试验数据进行了回归分析。研究结果表明：随着温度及保温时间的增加，脱碳层深度增加，并且与保温时间的开方成正比；在1 000～1 100℃时，脱碳层有一个低谷；脱碳对钢的淬硬性有明显影响，随着脱碳层深度增加，钢的硬度降低。

Abstract: Surface decarburization is one of the important processes in hot-rolled plate production.Decarburizing characteristics of 50CrV4 steel and its effect on hardenability of steel at 650~1 100℃ were investigated in the laboratory.According to the diffusion theory,the test data were studied through regression analysis.The research shows that the decarburized depth increases with the increase of temperature or holding time,and the depth is proportional to the extraction of the holding time.There is a minimum value in decarburized depth appearing at 1 000~1 100℃.The hardness of the steel decreases with the increase of the decarburized depth.
