Аннотация | Presented are the results of theoretical study of energy-power parameters of combined rolling-andpressing (CRP) process of press-products of AMg6 (АМг6), 01417, 8176 alloys. Choice of these alloys is governed by the fact that their alloyage by different elements like titanium, iron, lanthanum, cerium etc., causes difficulties on non-cutting sha ping and producing long-length semifinished products of electrotechnical destination. It is shown that making such semifinished goods of these alloys is non-manufacturable even with the use of traditional direct pressing operations on horizontal hydraulic presses; it is characterized by increased labour-intensiveness and requires higher power inputs. In this connection, the goal to be sought in this paper is to investigate possibility of processing the above mentioned alloys by method of combined continuous rolling-extrusion (CRE) as well as to determine powe renergy parameters of the process depending on varying temperature of semifinished product, degree and rate of metal deformation. The efforts, affecting the die and the rolls during combined processing has been calculated with the use of rheological characteristics of selected alloys, determined by the hot torsion method; analysis of their changes, depending on deformative and temperature-speed parameters for various combinations of the groove and diameters of the die has been also carried out. Ascertained have been the changing mechanism of energy-power parameters and their limiting value on realizing the process of combined rolling-extrusion at the combined processing plants of different design in the given range of varying parameters. There also has been made the recommendations on designing the technology of low-plastic alloys combined treatment for a CCRE-4 (СЛиПП-4) experimental-industrial plant placed into operation at Irkutsk aluminium smelter. | |
