川崎钢铁公司研制成功利用生石灰进行铁水脱硫的新技术,脱硫成本仅为以往碳化钙脱硫法的三分之一,质量以及由于脱硫产生的铁损与碳化钙脱硫法相同。一般铁水中含硫量0.035%,过去利用喷吹碳化钙脱硫,使硫含量降至0.015%。生产碳化钙耗电量大,电价又高,因此着手研究利用生石灰脱硫。只吹生石灰反应速度慢,达不到满意的效果,因此将生石灰粉
Kawasaki Steel Co., Ltd. successfully developed a new technology that utilizes quicklime for hot metal desulphurization. The cost of desulphurization is only one-third that of the conventional calcium carbide desulphurization process. The mass and the iron loss due to desulphurization are the same as those of the calcium carbide desulphurization process. The general content of 0.035% sulfur in hot metal, the past use of calcium carbide spray blowing desulfurization, the sulfur content reduced to 0.015%. Production of calcium carbide power consumption, high electricity prices, so proceed with the study of the utilization of quick lime desulfurization. Only slow lime reaction rate, less than satisfactory results, so quick lime powder
