摘要: 根据铁水预脱硫反应的热力学函数和脱硫反应速率,分析了有利于铁水预脱硫的条件。用10kg中频感应炉及无级变速螺旋搅拌器进行了石灰基铁水预脱硫试验,通过正交试验,得出使用成分为44%石灰、3%焦炭、22%电石、18%萤石、13%工业碱和用量为10 kg/t的脱硫剂对铁水进行预脱硫,可使硫含量降至0.010%0.013%,脱硫率达86.25%。

Abstract: Based on thermodynamic function of hot metal predesulphurizing reaction and desulphurizing reaction rate, the conditions beneficial to hot metal predesulphurization was analyzed. The test of lime-based hot metal predesulphurization was carried out by a 10 kg medium frequency induction furnace with stepless speed changing screw stirrer, and based on orthogonal experiment it was obtained that as the hot metal was predesulphurized by using predesulphurizer of 44% lime, 3% coke, 22% calcium carbide, 18% fluorite and 13% industrial alkali with dosage 10 kg/t, the sulphur content in metal decreased to 0.010% 〜0.013%, the desulphurizing rate was up to 86.25% .
