Method of liquid steel production with slag recycling in a converter, equipment to employ the method
摘要
<p>The invented method consists of the fact that slag from the end of a steelmaking process in a converter is recycled at the beginning of the steel converter process. Once the silicon oxidises, the slag is removed and substituted with new slag made of lime in particular as well as other admixtures, as the case may be. It means that the slag is not removed at the end of the steelmaking process, but in the middle of it. This decreases the amount of the slag due to better utilisation of the refining capacity of the slag and due to a smaller content of iron oxides while preserving desired characteristics of the metal. Application of the process thus increases metal yields. Auxiliary equipment makes slag-off easier.</p>
