引言一百年前,贝塞麦发明了转炉炼钢法.这种炼钢法得到的钢比当时坩锅钢的成本要低得多,产量要高得多.碱性托马斯转炉吹炼法的提出也解决了高磷生鉄的吹炼问题.但由于工业发展,废钢量的增多,而转炉操作方法又不能利用大量废钢,以及底吹转炉钢含氮量较高,侧吹转炉产量较小,转炉操作控制较为困难等缺点,使转炉吹炼法大部份地被平炉炼钢所替代.虽然这样,但在某些地区因为生铁成份限制和废钢缺乏仍然保留和建立了相当数量的转炉钢厂.并对改善转炉操作,提高转炉钢的质量进行了许多研究.
Introduction Bessemer invented the converter steelmaking method one hundred years ago, and the steel obtained from the steelmaking process was much lower in cost and yield than the crucible steel of that time. The basic Thomas Converter process But also because of industrial development, an increase of scrap, and the converter can not use a large number of operating methods, as well as the bottom blowing high nitrogen steel, side blown converter output is small , Converter operation control is more difficult shortcomings, so that most of the converter blowing method is replaced by open hearth steelmaking.However, in some areas but because of the limitations of pig iron composition and the lack of scrap still retained and established a considerable amount of converter steel Many studies have been conducted on improving converter operation and improving converter steel quality.
