摘要
采用3种端淬曲线预测模型计算两炉次高铁齿轮用钢18CrNiMo7-6的端淬曲线,对比端淬硬度检测结果,分析了不同模型的预测误差。结果表明,金满模型的预测结果与端淬试验检测结果误差较小,可以用做这类钢的端淬结果预测。根据端淬曲线预测与实测结果的对比分析,结合相关高铁齿轮用钢技术条件的硬度规范对高铁齿轮用钢18CrNiMo7-6的冶炼成分控制给出了建议。
Three prediction models were used to calculate and predict the end-quenching curves of two batches of 18CrNiMo7-6 steel for high-speed railway gears,and then the prediction errors of different models were analyzed by comparing with the end-quenching test results.The results show that the Jin model obtains small error compared with the end-quenching test results,and can be used to predict the end-quenching curves of the tested steels.According to the comparative analysis of the predicted and the measured results of the end-quenching test,and combing with the hardness specification for technical conditions of the high-speed railway gear steels,the controlling method of the smelting composition of 18CrNiMo7-6 steel for high-speed railway gears is proposed.
