硫、磷、氧是绝大多数钢中有害的元素。对其控制能力如何,是评判一个钢铁企业炼钢水平,从而高附加值新产品开发水平高低的重要标准之一。经过多年的努力,攀钢“三低”炼钢技术跻身国内先进行列,为攀钢调整品种结构,做精钢铁提供了重要的技术支撑。攀钢钢研院与新钢钒相关单位一 Sulfur, phosphorus, oxygen is the most harmful elements in steel. It is one of the important criteria for judging the level of steel making in a steel enterprise so as to control the development of new value-added high-value-added products. After years of hard work, Panzhihua Iron and Steel “three low” steelmaking technology ranks among the advanced ranks in the country, which provides important technical support for Pangang to adjust its variety structure and make fine steel.
