Abstract

1. Доменная печь, включающая плазмотроны, расположенные в верхней части горна печи, отличающаяся тем, что электроды плазмотрона выполнены в виде соосно расположенных с зазором между ними графитовых труб.2. Способ доменной плавки, включающий загрузку шихты, нагрев и расплавление ее, подачу в плазмотроны плазмообразующего газа, отличающийся тем, что шихту нагревают и расплавляют плазмой, а в качестве плазмообразующего газа в зазор между трубчатыми графитовыми электродами подают восстановительный или окислительный газ для получения чугуна, стали или стального полупродукта.3. Способ по п.2, отличающийся тем, что через внутренний трубчатый графитовый электрод подают тот же газ, что и в зазор.1. A blast furnace, including plasmatrons located in the upper part of the hearth of the furnace, characterized in that the electrodes of the plasmatron are made in the form of graphite tubes coaxially located with a gap between them. A method of blast furnace smelting, including charging a charge, heating and melting it, feeding a plasma-forming gas to the plasmatrons, characterized in that the charge is heated and melted by plasma, and as a plasma-forming gas, a reducing or oxidizing gas is supplied to the gap between the tubular graphite electrodes to obtain cast iron, steel or steel semi-finished product. 3. The method according to claim 2, characterized in that the same gas is supplied through the inner tubular graphite electrode as in the gap.
