摘    要：客户对于高品质钢的不断需求推动着铁水外部脱硫技术的发展。从相对简单的机械搅拌法到较成熟的喷吹技术,炼钢工作者不断地在生产成本和操作效率之间寻求最佳的平衡点。镁和石灰复合喷吹法是一项经过生产实践证明了的成熟技术,为炼钢生产者们提供了一种可靠的、可重复且满足生产需要的经济脱硫方法。

Abstract: The evolution of external hot metal desulphurization has been driven by the ever-increasing consumer’s demand for higher quality steels.From the relatively simple practice of mechanical stirring to the more sophisticated techniques of lance injection,steelmakers have been in constant search for the perfect balance between manufacturing costs and operational efficiency.Co-injection of magnesium and lime is a proven successful method of desulphurizing hot metal that offers steel producers a reliable,repeatable and economical means of meeting their production requirements.
