攀钢有三座120吨氧气顶吹转炉,自1971年投产以来转炉生产的各项技术经济指标已达到设计标准和较好的水平。但由于铁水雾化提钒比例增加,大量采用提钒的铁水(半钢)炼钢,半钢温度低、发热元素硅、碳低、而硫又高(平均0.065％左右),因此转炉炼钢温度感到严重不足,尤其炼重轨、D_(60)等高碳钢更感困难。转炉吃废钢很少(20kg/t钢左右)每年有20多万吨初轧切头外调,这直接影响攀钢经济效益的提高。随着攀钢二期工程的建设和对
Panzhihua Iron and Steel has three 120-ton oxygen top-blown converter, since 1971 put into operation all the technical and economic indicators converter has reached the design standards and a better level. However, due to the increased proportion of vanadium in molten iron, the vanadium-rich molten iron (semi-steel) steelmaking is used in a large amount, the temperature of semi-steel is low, the elemental silicon and carbon are low, and sulfur is high (average about 0.065% Temperature is seriously inadequate, especially heavy rail, D_ (60) and other high-carbon steel more difficult. Few scrap steel converter (20kg / t steel around) every year more than 200,000 tons of rolling head cut, which directly affect the economic benefits of climbing. With the second phase of Panzhihua Iron and Steel Construction and right
