Abstract: The invention refers to a jig clamping device for tension elements for metallurgic converters, particularly alternating converters which are cocked or tightened at their vessel bearing projections or extensions against the corresponding counterbearings of the annular support or frame for the vessel with at least one tension element, consisting of a hydraulic piston-cylinder unit transmitting tensile force onto the tension element.

Abstract: 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.
