Abstract

Винахід належить до галузі чорної металургії. Спосіб плавлення сталі в дуговій електропечі включає завантажування у ванну печі шихтових та навуглецьовуючих матеріалів, додавання у піч рідких добавок та їх плавлення, при цьому перед завантаженням у ванну печі шихтових матеріалів в неї зливають кінцевий шлак попередньої плавки з прилеглим до цього шлаку шаром металу у кількості 5-15 відсотків ємності всього металу у печі, та використовують навуглецьовуючий матеріал, що упресовують на розливний носок печі у кількості 1-2 т/г, який, неповністю згораючи, не потрапляючи до ванни печі, створює в ній відновлювальне середовище. Винахід дозволяє зменшити втрати металу зі шлаком при його розливанні.The invention relates to the field of ferrous metallurgy. A method of melting steel in an arc furnace involves loading in the furnace of the furnace charge and carbonizing materials, adding to the furnace liquid additives and melting them, and before loading into the furnace furnace of the charge materials in it merge the final slag of the previous melting with the adjacent slag metal in the amount 5-15 percent of the capacity of all the metal in the furnace, and use a carburizing material that is pressed onto the pouring toe of the furnace in an amount of 1-2 t / h, which, incompletely combusting without entering the furnace bath, creates it restorative environment. EFFECT: invention makes it possible to reduce the loss of metal with slag when casting.
