目前,在国内合结齿轮钢都采用电炉和平炉冶炼、而且均采用圆钢锻制齿轮。作者于1980年1月提出“用纯氧顶吹转炉冶炼合结齿轮钢、用方坯代替圆钢模锻齿轮等”建议。好处:在不降低齿轮质量、不增加齿轮钢消耗、不改变现行齿轮制造工艺情况下,减少一半轧钢工序、节约成本、吨钢节约120公斤标准煤、降低齿轮材料费20％。而且还可以提高我国纯氧顶吹转炉炼钢及模锻水平。建议提出后,得到机械工业部(原农机部、一机部)、齿轮厂、拖拉机制造厂、汽车制造厂等支持。并于1980、1981年与南昌齿轮厂、第一拖拉机制造厂合作,进行纯氧顶吹转炉25MnTiBRE、20CrMnTi85方坯锻制齿轮试验,取得了良好的结果。试验与结果首钢纯氧顶吹转炉20CrMnTi、25MnTiBRE钢
At present, the domestic combined gear steel are used electric furnace and open hearth smelting, and are made of round steel forging gear. In January 1980, the author put forward the suggestion of “using pure oxygen to blow the converter to sinter the gear steel and replace the round steel forging gear with a billet.” Advantages: Reduce half of the rolling process, cost savings, 120 tons of standard coal per ton of steel savings, reducing gear material costs 20%, without reducing gear quality, without increasing the consumption of gear steel, without changing the current gear manufacturing process. But also can improve our country pure oxygen top blown steelmaking and die forging level. After the proposal was made, it was supported by the Ministry of Machinery Industry (formerly Agricultural Machinery Department, Machinery Department), Gear Plant, Tractor Manufacturing Plant and Automobile Manufacturing Plant. And in 1980, 1981 and Nanchang Gear Factory, the first tractor manufacturer, pure oxygen top-blown converter 25MnTiBRE, 20CrMnTi85 billet forging gear test, and achieved good results. Test and results Shougang pure oxygen top-blown converter 20CrMnTi, 25MnTiBRE steel
