Аннотация: The article provides results of experimental studies for production of hot-pressed and calibrated bars made of alloy 6082 by a method of ingotless rolling-extrusion (IRE) of long-length press products made of alloy 6082 at the experimental installation SLIP-2,5. Rational deformation regimes for processing under specified temperaturПоказать полностьюe and rate conditions are determined. It is established that the process is guaranteed to be implemented with the following parameters: roll rotation speed 4 rpm; melting temperature 750°C; extension during pressing 7.3–10.0; compression during rolling 50%. The data obtained for properties of deformed semi-finished products manufactured according to the proposed technology make it possible to assert that the level of mechanical properties of calibrated bars corresponds to the thermally-strengthened state of alloy 6082 according to the specifications of standard EN 755–2. In addition, comparison of the results obtained for determining bar mechanical properties obtained using the IRE method makes it possible to conclude that it is comparable to the level of properties of bars made of this alloy manufactured under hot pressing production conditions. The technical and economic analysis carried out for factory conditions calibrated bar manufacture made of alloy 6082 showed that introduction of new technology using ingotless rolling-extrusion makes it possible to reduce production cost on an average by 15.5%.
