讨论了关于钢中非金属夹杂物目前的研究还不够深入、且值得深入研究的几个课题方向,包括夹杂物三维形貌的检测、复合脱氧的热力学、钢液的钙处理、非金属夹杂物变形能力和其熔点与成分的关系、精炼渣对夹杂物的调控能力特别是渣碱度对夹杂物成分和数量的影响、合金和辅料质量对夹杂物成分的影响、连铸过程浸入式水口结瘤的机理、耐火材料和钢液的反应机理、夹杂物尺寸和成分随时间变化的动力学以及和宏观流场的耦合研究等。以上这些方面都是这一领域必须值得关注和深入研究的内容。在以后的5~10年内解决这些问题并能用于指导生产实践,将是解决钢中非金属夹杂物的关键。
The current research on non-metallic inclusions in steel is still not deep enough and several research topics deserved further study, including the detection of three-dimensional inclusions, the thermodynamics of composite deoxidation, the calcium treatment of molten steel, the non-metallic inclusions Deformation ability and its melting point and composition of the relationship between the refining slag control of inclusions in particular the impact of slag basicity on the composition and quantity of inclusions, the quality of the alloy and auxiliary materials inclusions, the continuous casting process submerged entry The mechanism of the neoplasm, the reaction mechanism of the refractory material and the molten steel, the kinetics of the change of the size and composition of the inclusions with time, and the coupling research with the macroscopic flow field. These are all aspects that must be worthy of note and in-depth study in this area. In the next 5-10 years to solve these problems and can be used to guide the production practice, will be the key to solve the non-metallic inclusions in steel.
