东北大学冶金技术研究所开发了以活性石灰为基的脱硫系列产品。本产品采用优质原料,经特殊工艺(已申报专利)技术加工精制而成超细粉(粒度可达320目)。再配以金属镁粉(或其他强化脱硫粉剂)制成系列脱硫粉剂。有适用于铁水预处理的脱硫粉剂。也有用于钢包精炼的脱硫粉剂多种产品。本产品具有优良的防潮性能,颗粒表面为矿物质覆盖层,冷水浸泡60分钟不粉化,可远程运输,存储期可达一年。其活性指数达320以上;比表面积为8～10以上;脱硫率达
Institute of Metallurgical Technology Northeastern University developed a lime-based active desulfurization products. This product uses high-quality raw materials, the special process (has been declared patent) technology refined from ultra-fine powder (size up to 320 mesh). Coupled with metal magnesium powder (or other enhanced desulfurization powder) made of a series of desulfurization powder. There are suitable for hot metal desulphurization powder pretreatment. There are also many products for desulphurization powder for ladle refining. This product has excellent moisture resistance, the surface of the particles of mineral coating, cold water immersion for 60 minutes not powder, can be transported remotely, the storage period of up to one year. The activity index of 320 or more; specific surface area of 8 to 10 or more; desulfurization rate of up to
