宝钢曾先后采用了混铁车（CaO系、CaC2系脱硫剂）和铁水包（Mg系脱硫剂）两种脱硫方式。当铁水原始硫为150～300ppm时，脱硫后铁水硫含量可达10～30ppm的水平。众所周知，转炉的脱硫能力是相当有限的。特别在铁水原始硫含量很低的情况下，由于入炉的石灰、废钢等炉料带有较高的硫，往往出现转炉过程回硫现象。一般来说，仅靠铁水预处理要稳定生产硫含量小于30ppm的钢是有困难的。在转炉出钢后对钢水进行炉外脱硫势在必行。

但在一定条件下，脱硫率随着喷吹速度的增加而升高。在一定的喷吹条件下，尽管喷吹速度的增加幅度相同，脱硫率的升高幅度并不相同。喷吹速度增加，单位时间内喷吹量增加，镁粉在铁水中的分散性不好，脱硫反应不充分。依靠提高喷吹速度来提高脱硫率不是的方法。喷吹速度过高，降低了镁粉的利用率，喷吹速度太低，虽然能提高镁粉的利用率，但喷吹时间延长；温降大、生产率低，工艺上也是不可取的。所以，合适的喷吹速度既能提高镁粉的利用率，又不至于使脱硫时间过长。
