ABSTRACT:
A method and apparatus forproducing coated slabs of metal, particularly strips of steel, in which a metal slab is guided through the bottom of a vessel filled with molten metal having the same or different composition as the metal slab, wherein the dwell time of the metal slab is selected in dependence on the melting bath level, the casting speed, the metal slab thickness and the preheating temperature of the metal slab in such a way that the molten metal deposited on the metal slab has a desired thickness of a multiple of the initial thickness of the metal slab, and wherein the metal slab with the layer crystallized onto the metal slab is subjected to a smoothing pass after emerging from the melting bath. The smoothing pass is carried out when the surface temperature of the crystallized slab is smaller than the solidus temperature of the melting bath and, thus, at least the surface of the crystallized layer is solidified.
