上海宝山钢铁总厂在消化、吸收全套引进的日本OG成套技术的基础上,结合国情,对转炉工序综合采取25项节能措施、降低消耗,提高回收,于1989年起,实现转炉工序负能炼钢,在国内实现零的突破,挤身于世界先进水平。目前,我国各大型钢厂转炉工序能耗一般在20kg/t.s以上。宝钢职工狠抓节能降耗,使转炉工序吨钢能耗在1989年即达到—1.05kg/t.s,全国首家实现负能炼钢。1993年,进一步降为—4.0kg/t.s,连续5年保持负能炼钢纪录,取得显著节能效果和经济效益。该厂转炉炼钢采取的主要措施如下:
Shanghai Baoshan Iron and Steel Plant in the digestion and absorption of a full set of imported Japanese OG complete sets of technology, based on the combination of national conditions, the converter process to take comprehensive 25 energy-saving measures to reduce consumption, improve recovery, in 1989, to achieve negative energy conversion process Steel, to achieve zero breakthroughs in the country, among the world’s advanced level. At present, the energy consumption of major steel converter processes in China is generally above 20kg / t. Employees of Baosteel paid close attention to saving energy and reducing consumption so that the energy consumption per ton of steel in the converter process reached -1.05kg / t.s in 1989, and the country’s first steelmaker to realize negative energy. In 1993, it was further reduced to -4.0kg / t.s, maintaining a record of negative energy steelmaking for five consecutive years, achieving remarkable energy-saving results and economic benefits. The plant converter steelmaking to take the following major measures:
