An installation is provided for supplying materials into a metallurgical unit by the alloying steel for synchronizing the process of melting the supplied materials and reducing the alloying elements. The installation includes a distributor gear made as a funnel and a swivel launder with a drive, and intermediate hoppers interconnected with a pipe-chute. The installation is provided with a housing having a lid and means for fastening to structures of a plant. The funnel is mounted in the lid, the swivel launder is mounted under the lid and the intermediate hoppers are positioned radially in the housing to form a cavity by hopper surfaces facing a longitudinal axis of the installation, said cavity being separated from the interior of the hoppers, which are coupled to the pipe chute by discharge openings formed therein and shutters mounted to move relative to a longitudinal axis of a hopper.

The inventive method is used for optimising a hot and/or cold strip mill process. Said method consists in discreetly measuring the technological parameters of a strip milling and the angular rates of the working rollers of mill stands and table rollers, in defining the liner speed of the strip and selecting a specified number of strip sections having an equal length and used for a subsequent averaging of at least three values of technological parameters for each section, in determining the normative part of the length of the strip, which is divided into sections, for a specific range of rolled products, defining useful quality for each section with respect to the averaged values of the technological parameters of the section rolling, comparing the useful quality with prescribed limits, determining the part of the strip length for which the useful quality values lie within prescribed limits and in using said technological parameters as a standard for milling a strip of the same range or for the range close thereto if the thus obtained part of the strip length is equal to or higher than the normative part, or for rectifying the technological parameters if the thus obtained part is lower than the normative part.
