ABSTRACT:
In an arrangement for the production of steel from solid and/or liquid charging materials, such as pig iron, heavy scrap and light scrap, a liftable and lowerable heating-refining arrangement and, if desired an arrangement for supplying further additions are positioned in a refactorily lined refining vessel. In order to be able to use as high a scrap portion of the materials charged as possible without substantially increasing the time required until the end of the refining operation per charge, the heating-refining arrangement consists of a plasma burner, a jacket surrounding the plasma burner for supplying oxygen, and a cooling jacket surrounding that jacket, a counter-electrode being arranged in the bottom of the refining vessel.
