Abstract

The paper presents energy and technological indicators and designs of improved electric furnace units for melting steel from iron ore raw materials (IOR). A method of controlling an arc furnace with a continuous IOR supply is proposed, which gives the opportunity to control and regulate the active power of the furnace, thermal processes in the welding bath of the electric arc, as well as in the unit as a whole. The design of a ladle unit for out-of-furnace melt treatment is presented, which allows the melting of high-quality electrical steel and simultaneous treatment with inert gases. At the same time, it is possible to reduce the metal carbon monoxide and IOR melting time.
