ABSTRACT OF THE DISCLOSURE: In a method of, and arrangement for, producing molten pig iron or steel pre-material iron-oxide-containing raw-material particles are top-charged into a fluidized bed formed of carbon particles and an oxygen-containing carrier gas. When passing the fluidized bed, the raw-material particles are heated, reduced and smolten. In order to achieve a better utilization of energy with such a method, i.e. to considerably lower the total energy input, additional energy is supplied to the fluidized bed by plasma heating.
