一、概述近年来随着炼钢技术的飞跃发展,各种炉外精炼方法得到广泛的应用。目前炼钢技术发展的主要动向,是将原来在一个容器内来完成的冶金反应,逐步地走向在两个或多个容器内来完成,从而为加速冶金反应提高质量提供了前景。现在工业生产中使用的炉外精炼方法不下数十种,其主要目的是应用各种炉外精炼方法进行严格控制化学成分,降低钢中气体含量
First, an overview In recent years, with the rapid development of steelmaking technology, a variety of furnace refining method has been widely used. At present, the main trend of the development of steelmaking technology is to complete the metallurgical reaction originally completed in a container and gradually move it into two or more containers, thereby providing a prospect for accelerating the quality improvement of the metallurgical reaction. Now industrialized use of the furnace outside the method of refining dozens of its main purpose is to use a variety of furnace refining methods to strictly control the chemical composition and reduce the gas content of steel
