Abstract

In order to prevent molten steel reoxidation in the tundish during continuous casting, argon injection into the shroud is applied. The injected argon bubbles in molten steel may change the molten steel flow pattern in the tundish. Consequently, the ratios of dead zone, plunger zone and well-mixed zone would change. Also, the motion of inclusions in the molten steel of tundish would change resulting from argon injection. The current word developed a coupling multiphase flow mathematical model. Basing on the developed model, the present work has researched the influences of argon injection on the molten steel flow pattern, inclusion motion characteristics in the tundish.

连铸中间包包壳喷氩优化的数值研究

在连铸过程中，为防止钢水在中间包内再氧化，在包壳内喷氩。钢水中注入的氩气气泡会改变中间包内钢水的流动模式。因此，死区、柱塞区和混合区的比例会发生变化。同时，氩气的注入也会改变中间包钢液中夹杂物的运动。目前国内外发展了一种耦合多相流的数学模型。在此基础上，研究了喷氩对中间包内钢液流态和夹杂物运动特性的影响。

期刊介绍： Metallurgical Research and Technology (MRT) is a peer-reviewed bi-monthly journal publishing original high-quality research papers in areas ranging from process metallurgy to metal product properties and applications of ferrous and non-ferrous metals and alloys, including light-metals. It covers also the materials involved in the metal processing as ores, refractories and slags. The journal is listed in the citation index Web of Science and has an Impact Factor. It is highly concerned by the technological innovation as a support of the metallurgical industry at a time when it has to tackle severe challenges like energy, raw materials, sustainability, environment... Strengthening and enhancing the dialogue between science and industry is at the heart of the scope of MRT. This is why it welcomes manuscripts focusing on industrial practice, as well as basic metallurgical knowledge or review articles.
