摘要
介绍了喷吹法和搅拌法的脱硫机理,通过热力学计算了单独喷吹颗粒镁、复合喷吹Mg/CaO和搅拌石灰的脱硫极限,分别为10-4%数量级、10-7%数量级和10-3%数量级。对喷吹法和搅拌法的脱硫效果及利弊进行了对比分析,以便各钢铁企业根据实际情况选择合适的脱硫方法。
The desulphurization mechanics of hot metal injection and stirring are introduced.The desulphurization limit of injected with Mg and Mg/CaO or stirred with CaO is theoretically calculated.The desulphurization capability of every system is 10-4%,10-7%,10-3%quantitative rank.The effects of desulphurization and the advantages and disadvantages between injection method and stirring method are compared,in order to guide the steel company choosing suitable desulphurization methods according to their actual situation.
