一镁在黑色冶金中的应用从化学观点看,镁在黑色冶金中的二大作用为脱氧与脱硫。但因镁的沸点较低,又易於燃烧,故实际应用较为困难。球墨铸铁发明以後,镁在钢鉄工业中的应用方才受到重视;关於镁的脱氧力与脱硫力也有一些研究结果发表。此外,镁与氮间也有很强的亲和力,这方面的研究还很少看到。镁在球墨铸铁方面的应用已为—般所熟知,无庸赘述。钢液用镁脱氧虽早有人建议,终因加镁技术上的困难,试验者较少。葛尔茨曼与里查特生用二种不同方法加镁於钢液中,获得一定的 A magnesium in black metallurgy From the chemical point of view, the two major roles of magnesium in black metallurgy for the deoxygenation and desulfurization. However, the lower boiling point of magnesium, but also easy to burn, so the practical application more difficult. After the invention of ductile iron, magnesium in the steel industry has just been the application of the importance of; on the deoxidization of magnesium and desulfurization power have also published some findings. In addition, magnesium and nitrogen also have a strong affinity between the research in this area is seldom seen. The use of magnesium in ductile iron has been well known and needs no further explanation. Magnesium deoxidation of molten steel, although it has long been suggested, the final result of magnesium technical difficulties, less experimenter. Geertzman and Richardson used two different methods to add magnesium to the molten steel to obtain a certain amount
