摘要中间包是炼钢流程从间歇操作转向连续操作的重要衔接点,对于促进钢液的分流、净化、减轻铸坯宏观偏析、提高等轴晶率以及铸坯质量有着十分重要的作用。随着对连铸坯质量和钢水洁净度要求的不断提高,新型中间包冶金技术层出不穷。这其中,中间包电磁感应加热因同时具备高效稳定的中间包温度和夹杂物去除功能,有利于实现钢水低过热度恒温浇铸,逐步在连铸生产中得到应用。此技术的应用、研究现状及未来发展趋势进行了详细探讨。

Abstract：Tundish is an important connection point of steelmaking process from intermittent operation to continuous operation. It plays a very important role in promoting the diversion and purification of liquid steel, reducing the macro segregation of slab, improving the equiaxed grain rate and slab quality. With the continuous improvement of the requirements for the quality of continuous casting slab and the cleanliness of molten steel, new tundish metallurgical technologies emerge one after another. Among them, electromagnetic induction heating in tundish has the functions of high-efficiency and stable tundish temperature stability and inclusion removal, which is conducive to low superheat constant temperature casting of molten steel and has been gradually used. The application, research status and future development trend of this technology are discussed in detail.

Key words： tundish electromagnetic induction heating inclusion low overheat slab quality
