“六五”和“七五”期间,鞍钢的低合金钢生产有很大发展,1990年低合金钢比达到15.35%。随着低合金钢特别是微合金钢的发展,冶炼工艺有了很大的进步。“八五”期间,鞍钢应建立有力地推动机制,确立合理的指标和发展速度,继续发展微合金钢,注意钢种的创新和仿制,并加强软科学的研究。“八五”末期低合金钢产量要突破30%,努力开发低合金钢新品种,“观标”率达到60～70%,年增经济效益5000～8000万元。 During the “Sixth Five-Year Plan” and the “Seventh Five-Year Plan” period, the production of low-alloy steel in Ansteel has greatly developed. In 1990, the ratio of low-alloy steel reached 15.35%. With the development of low alloyed steels, especially microalloyed steels, the smelting process has been greatly improved. During the Eighth Five-Year Plan period, Ansteel should establish a vigorous mechanism to promote the establishment of reasonable targets and speed of development, continue to develop micro-alloyed steel, pay attention to the innovation and imitation of steel grades, and strengthen the research on soft science. At the end of the “Eighth Five-Year Plan” period, the output of low-alloy steel should exceed 30%. Efforts should be made to develop new low-alloy steel varieties with the rate of 60-70% and the annual economic benefit of 5000-80 million yuan.
