| Abstract: | The porthole die extrusion can often be used to produce the section extrusion of nonferrous metals. Based on the results of numerical simulation and the experimental results of practical extrusion pressure for MB2 alloy, this paper gives a simple engineering algorithm of the extrusion force during the process of the porthole die extrusion. Compared with the experimental results, the algorithm has less than 10% relative error. Therefore, it can be reference for the practical application. |
