Arrangements of apparatus are provided for the automatic sequential additive treatment of metal smelts in a metal smelting plant in order to control and alter the component materials of the smelts, without the need for the physical transfer from the main production line plant to other areas for processing. Moreover, the arrangement herein brings about the required results without blocking or otherwise hindering the conventional access areas of the main production line, and provides a more accurate control of processing temperatures of the smelts during treatment procedures. This is achieved by incorporating a treatment station either in or adjacent the main production line, which station includes a plurality of treatment areas as required with branch lines parallel to or perpendicular to the main production line. The branch lines may be at the same level or suspended over the main production line and carry cranes or dollies or other treating equipment vehicles into and out of cooperating engagement sequentially with smelt ladles positioned in a particular treatment area. Each treatment area includes fixed couplings for cooperation with the individual pieces of equipment, such as desulphurization additive equipment moved into and out of each treatment area, with each treatment area having a control center for the sequential operation thereof. With this arrangement, the smelt ladles do not have to be removed entirely from the main production line area and transported to other areas for treatment, thus avoiding fluctuations in the temperature of the smelts during processing.
