ABSTRACT:
A process for feeding metal to molten metal, in particular for the purpose of melting solid metal such as scrap metal or dross granules, is such that at least part of the melt is divided and each divided part set into motion rotating in opposite directions so that at least two rotating streams or "rolls" of molten metal are produced. The central axes of these rotating streams of molten metal form an angle. The metal to be melted is charged at the place where the two "rolls" of molten metal meet. The "rolls" of molten metal are produced by introducing the molten metal into a pair of pipe lengths approximately perpendicular to their central axes and approximately tangential to the cross section of the said pipe lengths, the central axes forming an angle, or by causing the molten metal in the pipe lengths to rotate by means of electrodynamic forces.
