摘要
20CrMnTi热轧齿轮圆钢的热顶锻裂纹是八钢齿轮钢生产中的技术难点,每年产生多起用户质量异议。通过对齿轮钢热顶锻裂纹试样的形貌及金相组织特征的分析,阐述了造成热顶锻裂纹的各类冶金原因与轧制原因,并采取了改进措施,取得了明显效果。
The crack of forging crack of pinion steel 20CrMnTi is technique nodus. It works the demurrers of quality on per annum. To investigation of forging crack of pinion steel and metallographic examination, the text expatiates causations of metallurgy and causations of roiling for forging crack of pinion steel and preventive measures.
