The traditional Ti6Al4V alloys were obtained by the smelting reduction of V-Ti bearing beach placer by rotary hearth furnace and aluminothermic reaction in laboratory. First, it takes the aid of combined rotary hearth furnace and grinding magnetic separation process to prepare high titanium slag containing vanadium. In this study, a neural network model was used. The comparisons between experiment results and neural network simulation results show that GA-based on BP method can predict the degree of reduction and separation of iron and slag with higher prediction accuracy. Then by aluminothermic reaction process, the optimized process parameters for Ti-V-Al alloys were searched. Al can deoxidize metal V and Ti from the metal oxides of high titanium slag containing vanadium. At last, traditional Ti6Al4V alloy can be obtained by remelt and adjust the constituents.
