Increasing Demand

The growing interest in the process of hydrostatic extrusion is reflected by numerous publications on experimental results, fundamental researches and theoretical studies (e. g., [1] to [20]). In recent years it was the increasing demand for new materials and semiproducts with special cross-section dimensions and properties that substantiated the necessity of defining the application of hydrostatic extrusion in the field of non-ferrous metallurgy. Thus, it is the aim of the researches carried out with the experimental hydrostatic extrusion press type QEH 12 recently installed by the Swedish company ASEA in the Forschungsinstitut für NE-Metalle Freiberg of the VEB Mansfeld Kombinat “Wilhelm Pieck” to solve problems of materials and deformation engineering and to develop new technologies of producing special semiproducts from non-ferrous metals.

Regional Product

It is shown that Tuva has a sufficiently rich mineral and raw material diversity and the potential for their development. Nevertheless, the development of the republic is hindered by the existence of transport and infrastructure restrictions, to eliminate which, first of all, it is necessary to build a railway along the Kyzyl-Kuragino highway. On the other hand, given the border area of the territory that adjoins western Mongolia, there is a possibility of implementing various scenarios for the construction of railway tracks. The calculations performed to evaluate scenarios for the development of mineral resources of the republic using methods of intersectoral assessment shows that when implementing a pessimistic option for the development of the potential of mineral resources of Tuva (in which the construction of the railway to Tuva is frozen and only deposits of non-ferrous metals and gold are developed), the gross regional product of the republic will grow to 164 billion rubles, which will be 45% of the growth of this indicator in relation to the GRP of 2018. With the implementation of the optimistic option I, (in which it is planned to build a railway along the Kuragino-Kyzyl highway, coal deposits, non-ferrous metals, gold are being developed), the GRP of the republic will grow up to 351 billion rubles. In addition, calculations have been made for the construction of railways that would connect Tuva with Mongolia and China.

Increasing Demand

Rapid development of automotive industry brings increasing demand for die forgings made from non-ferrous metals. Market economy stimulates drop forges to produce forged pieces of highest quality and dimension precision with the accent on reduction in production costs. Precision die forging without flash belongs to progressive and economical technologies of die forgings production. This paper describes an experiment of precision forging in closed die of magnesium alloy type AZ 31. Given alloy type Mg-Al-Zn is suitable for bulk forming and is characterized by good hot formability. Achieved results may be applied in practice at production of longitudinal shaped forgings e.g. levers and connecting rods. In order to verify a design of closed die forging technology regarding the lever-shaped forged piece, simulation program MSC.SuperForge was used. Numeric simulation was significantly helpful at optimization of semi-product shape and dimensions and confirmed correct plastic flow of material in closed die cavity. The objective of this contribution was to point out current trends in searching for economical measures at production of die forgings from alloys of non-ferrous metals.
