Abstract
The study of deformation of solids by high-pressure liquid (hydrostatic extrusion) is not only an interesting research problem, but an applied one. Hydrostatic extrusion method is currently widely used in various sectors of industry – from mechanical engineering to the food industry. This field of research seems relevant and promising. The paper presents the calculation results for some parameters of continuous hydrostatic extrusion of materials, shows graphs of the dependence of the axial stress in the billet on the total pressure drop along the length and graphs of the dependence of the total pressure drop along the length on the working fluid flow rate in the annular gap. The calculations were performed for the adiabatic fluid flow and for the flow with partial heat transfer. Analysis of the calculation results showed that for fixed flow rates of the working fluid and specified heat transfer conditions, maximum axial stresses can be obtained by optimal values taken for the ratios of the working chamber and the billet diameters.
