有关获得非金属夹杂最少的合金问题,是研究人员经常注意的中心。为了制定减少非金属夹杂含量的新的生产方法,务须研究钢生产的不同阶段,以及在结晶过程中夹杂的行为。B.N.沃易斯基曾经建议,按炼钢过程中,夹杂形成的顺序对内部的非金属夹杂进行分类,如第一类钢水处于脱氧温度时所形成的夹杂;第二类发生在钢水冷却到液相线温度时的夹杂;第三类在钢锭结晶过程中,处于固一液双相区的液相中,液相线和固相线温度之间
The issue of getting the alloy with the least amount of non-metallic inclusions is a center that researchers often pay attention to. In order to develop new production methods to reduce the content of non-metallic inclusions, it is necessary to study the different stages of steel production and the behavior of inclusions in the crystallization process. BN Vierski has suggested that the internal non-metallic inclusions should be classified according to the order in which the inclusions were formed during the steelmaking process, such as inclusions formed when the first type of molten steel is at deoxidation temperature. The second type occurs when molten steel is cooled to liquid Phase inclusions; the third category in the ingot crystallization process, in the solid-liquid two-phase region of the liquid phase, liquidus and solidus temperature between
