随着国民经济建设对无缝钢管,尤其是小口径、薄壁管需求量的增长和对品种、质量要求的提高,我厂φ76mm无缝钢管机组工序间能力不平衡、工艺结构不合理、技术装备水平不高等问题十分突出。急需进行技术改造,使之形成以高质、低耗、多品种高效率和无“三废”为目标的生产体系,从而进一步发挥小型无缝钢管机组,在我省钢铁工业生产中的作用。1984年我厂制定了φ76mm无缝钢管机组总体技术改造分段实施方案:第一期(1984年—1985年)φ76mm无缝热轧机组升级,为全面技术改造在技术上准备条件;第二
With the national economy on the seamless steel pipe, especially small-caliber, thin-walled tube demand growth and the variety, quality requirements increase, I plant φ76mm seamless steel pipe unit capacity imbalance between processes, the process structure is irrational, technology Equipment level is not high, the problem is very prominent. The urgent need for technological transformation, so that the formation of high-quality, low-cost, high efficiency and variety of varieties and no “three wastes” as the goal of the production system, so as to further play a small seamless steel pipe unit in our province steel industry production role. In 1984, our factory formulated the sub-stage implementation plan for the overall technological transformation of the φ76mm seamless steel pipe unit: the first phase (1984-1985) of the φ76mm seamless hot-rolling mill unit was upgraded to technically prepare conditions for the full-scale technological transformation; the second
