Modeling the Process of Obtaining Bars from Aluminum Alloy 01417 by Combined Rolling-Extruding Method with Application of the Deform-3D Complex

Abstract

The results of computer simulation of the process of combined rolling-extruding of longish deformed semi-finished products from alloy 01417 are presented. A feature of the research is that continuously cast bars with a diameter of 12.5 mm obtained using an electromagnetic mold are used as a workpiece. This makes it possible to increase the manufacturability of processing and to obtain after rolling-extruding billets for drawing with a diameter of 5 mm with a large resource of plastic and strength properties. For this case the technological parameters and temperature and speed conditions of combined processing have not yet been studied, therefore, their analysis was performed using the Deform-3D software package. It has been revealed that the feasibility of the rolling-extruding process is significantly affected by the frequency of rotation of the rolls. Moreover, the process becomes unstable when the value of this parameter is 4 rpm, which can be explained by insufficient degrees of deformation during rolling, and consequently by the small value of the active friction forces acting on the contact surface of the metal with the rolls. As a result of this, the processing temperature conditions also change, which is also demonstrated using the developed computer model. As a result, it was found that for the stable course of the combined rolling-extruding process at the CRE-200 unit of a continuously cast billet with a diameter of 12.5 mm from alloy 01417 at a heating temperature of the billet of 550 °C and a tool of 200 °C, degree of deformation during rolling 44% and drawing ratio during extruding 18.6 the frequency of rotation of the rolls should be at least 8 rpm. The simulation data used during the implementation of the process at the combined processing unit CRE-200, the results of which made it possible to finally obtain electrotechnical wire with a diameter of 0.5 mm from 01417 alloy that meets the requirements of TS 1-809-63-2018.

“…2, using the laboratory CRE-200 unit (Table 3). When modeling using the DEFORM-3D complex the following conditions were accepted: the material of the rolls and dies is absolutely rigid; the diameter of the billet is 12 mm, and the diameter of the extruded product is 5 mm; the process takes place at a constant ambient temperature of 20 ℃; the temperature of the billet is taken equal to 550 °C, and the temperature of the tool is 200 °C; for calculations, the billet was divided into 10000 finite elements; the frequency of rotation of the rolls ω varied at two levels (4 and 8 rpm); Siebel friction coefficient was: on the contact surface of the roll -a billet equal 0.8, at the border of the roll -a die equal 0.5 [21].…”

Numerical Analysis of the Non-Stationary Thermal State of the Tool in the Combined Casting and Extrusion of Non-Ferrous Metals 

“…As studies of the methods of continuous extrusion of metals have shown [15][16][17][18][19][20][21][22][23][24], their use significantly increases the efficiency of the production of profiles from non-ferrous metals. One of the promising directions in the development of these technologies is the combination of continuous casting with extrusion on a Conform installation with a horizontal carousel mold [21][22][23][24][25][26]. During the operation of the installation, the metal melt is fed through the batcher into the annular groove of the rotating mold wheel and solidifies to contact with the stationary part of the container, formed at the interface of the groove with the arcuate segment (Fig.…”
