英文摘要：

With the help of the 3D-CAD software, the typical components of the converter system can be modeled manually and program automatically. The mechanical parameters can be picked up easily by the 3D-CAD API and then the curves of the tilting moment and the shape simulation of the molten steel can be obtained quickly and exactly. In the research, several assistant datum features are generated and their parameters can be adjusted. Taking the mass as the goal variant a kind of simple and practical dichotomy arithmetic for water surface approach is designed. Then the dynamic position of the molten steel surface through the whole tilting process can be simulated effectively. Considering one typical melting period, some calculating and simulating results are given.
