As a metallic material with strategy value ,vanadium have got extensive application in steel metallurgy ,metallic machining ,electron and aviation. Now our country has hold the devanadium technology and become one of the four greatest devanadium countries in the world. Oxygen converter devanadium now has become the main production method in our country. The process of devanadium is a high temperature chemical reaction process and the mechanism of reaction is very complex, the affect factor is also so many, and the influence by the variety of raw material and technics condition is also great, so it is very inconvenient to operate manually. In order to improve the level of devanadium technology and change the status that the target in production process is always variable, it is necessary to realization the computer control in production process and reduce the influence by the manual factor.On the process of developing the static devanadium model and thinking of the status that the devanadium process is still manual operation in our country, the oxygen converter devanadium is chosen as a specific research object from the point of view of industrial application in this paper. And on the basis of considering the demerits of the traditional mathematical model, the paper has developed a perfect self-study and self-adaptive static model by means of some artificial intelligence technology such as NN, CBR etc.Firstly this paper introduce the meaning of developing devanadium static model and discuss the application and development of the domestic and international research, and then thoroughly analyze the merits and demerits in these model-making methods. Aiming at the complexity of devanadium process, this paper put forward an advice that the more precise model should be made by means of the NN and other AI technology.On the basis of combining the characteristic of the technics theory and practical devanadium process, this paper conclude the internal affect factor of devanadium process and the main factor of static model. Then the paper develop a refrigerant model by means of traditional BP algorithm,statistics theory ,experience theory and thoroughly analyze the combination of these three methods and their predict precision .And then the paper put forward an advanced algorithm on the basis of combining the statistics theory and the problems on the traditional BP algorithm .The imitate results show that the algorithm has an ability of fast convergence speed andstrong study power. At the same time this paper discuss some technical problem about how to use the CBR technology to establish the spear position control model.At last, this paper develop a software for devanadium static control model by means of object-oriented programming language Visual C++ 6.0.
