近年来,法国黑色冶金科学研究所(IRSID)为了改善许多冶金过程中化学反应的动力学,在液体金属中吹入气体和各种粉状材料的混合物方面进行了很多的工作。例如:为了使电炉熔池增碳和强化高炉过程而吹入煤粉;为了在铁水包中进行生铁脱硫吹入石灰粉;在炼钢过程中吹入铁矿粉与铁合金粉;为了在转炉炼钢中冶炼高磷生铁而
In recent years, the French Black Metallurgical Institute (IRSID) has done a great deal of work to improve the kinetics of chemical reactions in metallurgical processes by blowing gas and mixtures of various pulverous materials into liquid metals. For example: in order to make the electric furnace molten pool carbon and strengthen the blast furnace process and blowing coal; in order to pig iron ladle desulfurization blowing lime powder; iron and iron powder and iron alloy powder blowing in the steelmaking process; Smelting high-phosphorus pig iron in steel
