Application of Сomputer Modeling for the Analysis of the Flow of Metal during the Settlement of Flat Billets

Computer simulation of the metal flow pattern during the settlement of flat billets is considered on the basis of the developed “equi-theory” based on the principle of the shortest normal, which makes it possible to build a drawing of a multi-contour billet according to the specified dimensions, to determine the metal flow separating lines, streamlines, to analyze the metal flow pattern, and to substantiate the use of technological methods and structural elements that prevent or reduce the risk of defects. The general characteristics of broadly oriented, special and highly specialized software complexes are presented, their advantages and weaknesses are noted. The results of computer modeling of the metal flow pattern for complex multi-contour workpieces using the developed EQUI software package are shown.
