杭州钢铁厂转炉分厂从1965年7月1日投产至今已有20年的历史。1979年5t×1地坑式氧气顶吹转炉生产能力达到11、2837万吨。同年4季度又将一座原地坑式侧吹转炉改造成5t氧气顶吹转炉,并增建了48×18m的铁水跨厂房。同年又将原主副跨厂房各延伸4跨并更新了几台行车。通过这些主要技术改造措施,理顺了5t×2氧气顶吹转炉的生产工艺流程,为生产发展打下了良好的基础。1979年钢产量达到16万吨,1983年上升
Hangzhou Iron and Steel Plant converter plant from July 1, 1965 put into operation has been 20 years of history. 1979 5t × 1 pit oxygen blowing furnace production capacity reached 11,283,700 tons. In the fourth quarter of the same year, another in-situ pit-side converter was converted into a 5-ton oxygen-top converter and a 48 × 18m hot metal plant was built. In the same year, the original main cross-plant each extended 4 cross and updated several vehicles. Through these major technological transformation measures, the 5t × 2 oxygen top-blown converter has been streamlined and has laid a good foundation for production and development. Steel production reached 160,000 tons in 1979 and rose in 1983
