今年九月,宝钢一期工程从原料到初轧全系列一次投产成功,这是我国冶金史上可喜的一页,宝钢不但全套引进国外设备,而且炼铁原料铁矿石90%以上依靠进口,宝钢成功地利用国外铁矿资源,将对我国钢铁工业的发展战略,起深刻的影响。一、技术上的突破宝钢高炉近乎全部使用国外矿,在国内高炉冶炼技术上没有先例。七十年代以来,国内一些钢铁厂吃过进口矿,但比例低,仅作我国自产精矿的配矿。而且宝钢使用的某些矿种,如澳矿粉、巴矿粉,对国内不少大钢铁企业的高炉冶炼工作者并不陌生,例如
In September of this year, Baosteel’s first-phase project was successfully put into production in full series from raw materials to early rolling. This is a gratifying page in the history of metallurgy. Baosteel not only introduced a full set of foreign equipment, but also imported more than 90% of iron ore raw materials, Baosteel The successful utilization of foreign iron ore resources will have a profound impact on the development strategy of China’s iron and steel industry. First, the technical breakthrough Baosteel blast furnace almost all the use of foreign mines, there is no precedent in the domestic blast furnace smelting technology. Since the seventies, some steel mills in China have eaten imported ore, but the ratio is low, only for China’s own concentrate production with ore. And some of the minerals used by Baosteel, such as Australian ore powder, Pakistani ore powder, is not familiar with blast furnace smelters in many large iron and steel enterprises, such as
