1 前言 1991年冶金部召开冶金产品实物质量座谈会时,曾对齿轮钢作过专题研讨。当时我国的轿车工业还刚刚起步,引进齿轮钢尚处在试制谈判阶段,产量很小。五年来,随着我国轿车工业的发展,新型齿轮钢的产量已有相当程度的增长,20CrMnTi一统天下的局面开始有所改观,但从全国齿轮用钢的生产情况来看,其统治地位仍未完全突破。
1 Introduction In 1991, the Metallurgical Department held a symposium on the physical quality of metallurgical products, and made a special discussion on gear steel. At that time, China’s car industry has just started, the introduction of gear steel is still in trial phase of the trial, the output is small. In the past five years, with the development of the car industry in our country, the output of the new type of gear steel has increased to a considerable degree. The situation of dominated by 20CrMnTi has started to change. However, the production status of national gear steel has not yet dominance Complete breakthrough.
