尽管钢水精炼技术的种类千变万化,但所采用的手段不外乎渣洗、真空、搅拌、喷吹和调温五类,它们是钢水精炼的基本操作单元。其中搅拌几乎是每一种方法都不可缺少的,因为通过搅拌可以扩大反应界面,加速反应物质的传递过程,增加冶金反应速率。较早出现的精炼方法是利用钢液本身的位能,依靠钢水的冲击力实现熔池的剧烈搅动,例如异炉渣洗、混合炼钢、TD、VC、SLD等。但随着对钢水质量要求的提高,钢水冲击搅拌
Although the variety of molten steel technology is ever-changing, it uses no more than five types of slag-washing, vacuuming, mixing, blowing and tempering. They are the basic operating units of molten steel refining. Among them, stirring is indispensable for almost every method, because the reaction interface can be expanded by stirring to accelerate the transfer process of reaction materials and increase the metallurgical reaction rate. The earlier refining method is to utilize the potential energy of molten steel itself and rely on the impact of molten steel to stir the molten pool violently, such as different slag washing, mixed steel making, TD, VC, SLD and so on. However, with the improvement of molten steel quality requirements, the impact of molten steel mixing
