由第一重型机器厂和东北重型机械学院共同开发研制的锻造半钢、锻造铸铁轧辊取得成功。每支轧辊的平均总轧材量均已超过九万吨,为含钼铸铁轧辊寿命的三倍,达到了八十年代国际先进水平。在研制过程中,采用了 Forged by the first heavy machinery plant and Northeast Heavy Machinery Institute jointly developed forged steel, forged cast iron roll success. The average total rolling volume of each roll has exceeded 90,000 tons, which is three times the life of the molybdenum-containing cast iron roll, reaching the international advanced level in the 1980s. In the development process, adopted
