Zagirov, Sergey B. Sidelnikov… Adaptation of Method Combined Rolling-Extruding for Production… non-ferrous metals and alloys. <...> The above approach is aimed for solution a number of practical problems, the most significant of which can be consider the use of more rational, compared to the traditional melting redistribution, ways to involving to the production circulation generated in one form or another in particular production different types of waste chips. <...> The effectiveness of the implementation of this method of processing waste chips provided a clear organization of work on their collection and storage, caused by a decline of deadweight losses of metal, lower cost of electricity for the metal production, and also the environmental conditions of production. <...> In addition for maximum performance of processing waste chips important to create conditions of uninterrupted operation used for this purpose aggregates for a sufficiently long period of time. <...> Known a device for force feeding of non-compact material (powder) into the rolls of rolling mill and rolling it in horizontal direction as a metal strip [1], consisting of a bunker a container and auger with a drive and setpoint block. <...> Due to the pressure generated by auger in the container, the device sequentially seals, and moves metal material and through setpoint block send it to the rolls located in a horizontal plane. <...> However, this device allows obtaining only <...>
