英语翻译分析了某低碳合金结构钢（20CrMnMoH）制的主传动主动齿轮渗碳淬火、高频退火后花键部位批量裂纹产生的原因,是由于渗碳淬火组织不良、高频退火工艺及锻坯组织控制不当造成.结果表明,严格控制锻坯质量、改进渗碳淬火及高频退火工艺,可避免高频退火后裂纹的产生.

Oh~Analyzed some low carbon alloy steel (20 crmnmoh) system of main transmission driving gear spline parts batch after carburizing and quenching, high-frequency annealing the reasons of the crack, is bad because the carburizing and quenching organization, high-frequency annealing and forging stock improper control of the organization. Results show that the strict control of forging billet quality, improvement of carburizing and quenching and high frequency annealing process, can avoid cracks after annealing at high frequency.
