摘要
从几个方面对多年来在钢中非金属夹杂物基础研究方面做的工作做简单介绍:钢中夹杂物和钢水洁净度的评估方法、稳态浇注和非稳态浇注的定义、非稳态浇注过程中形成的大颗粒夹杂物、总氧和大颗粒夹杂物的对应关系、脱氧过程夹杂物形成的热力学基础、钢水中夹杂物形核和长大的动力学研究和钢水中流体流动和夹杂物的运动、去除及被凝固前沿的捕捉。并讨论了钢中夹杂物研究下一步应该继续进行的工作,对洁净钢的生产提出了一些指导性意见。
The scientific studies of the current author on the fundamentlas of inclusions in steel was summarized, in cluding evaluation method of inclusions, steady and unsteady continuous casting, control of unsteady casting and big inclusions in steel, the independence of total oxygen on big inclusions, thermodynamics of steel deoxidation, nucleation and growth of inclusions in the molten steel, fluid flow and inclusion motion and entrapment during casting process. The further studies on inclusions in steel were also discussed. All the information was to provide useful guidance for the production of clean steel.
