Abstract

A process for the production of steel or iron poor in carbon, in which iron ore is heated electrically with coal and limestone in an arc furnace to produce molten metal which accumulates at the bottom of the furnace, characterized by being injected oxygen in the mass of molten metal to purify it and form steel or carbon-poor iron, with production of hot reducing gases that pass through the ore that is inside the furnace and reduce it even more.
