一、现状与五年成就目前全局共有型钢轧机29套,包括开坯轧机7套,棒材轧机13套,线材轧机3套与型材轧机6套。1979年起国民经济开始转入新的调整时期,型钢生产坚持挖潜、革新、改造,依靠技术进步,发挥原有轧机的作用,以发展品种,提高质量,节约能源,降低原材料消耗,提高生产效率与产品使用效率,走经济效益好的内涵扩大再生产的路子。五年来,成品钢材增加6.5%,型钢增加3.3%,型钢的短线产品增加11%。轧钢合格率提高到99.5%,获得创优产品已达16种。加热炉能耗大幅度降低(比78年节约40～50%),成材率由79年的81.96%提高到82.9%。这几年的技术进步主要表现在以下几方面。
I. Status Quo and Five-Year Achievements At present, there are 29 sets of overall profiled steel rolling mills, including 7 sets of blooming mills, 13 sets of bar mills, 3 sets of wire rod mills and 6 sets of profile mills. Since 1979, the national economy began to move into a new period of adjustment. The steelmaking industry persisted in tapping potential, reforming and rebuilding, relying on technological progress, and played the role of the original rolling mill to develop varieties, improve quality, save energy, reduce consumption of raw materials and increase production efficiency And product use efficiency, take the good economic benefits of the expansion of reproduction of the road. Over the past five years, finished steel increased by 6.5%, steel increased 3.3%, short-term steel products increased by 11%. Rolling pass rate increased to 99.5%, access to excellent products have reached 16 species. Heating furnace significantly reduced energy consumption (saving 40 to 50% over 1978), and the percentage of finished products increased from 81.96% in 1979 to 82.9%. In recent years, technological progress mainly in the following areas.
