A VD Temperature Forecast Model for Baosteel's EAF and Its Implementation Through Networks

The EAF production route is a typical mini-flow process of steelmaking. From electric arc furnaces and refining to continuous casting, the molten steel temperature system and molten steel temperature control are very important to guarantee the smooth running of the mini-flow process and quality of continuous casting billet. With long period of practice and great effort, some intelligent control technologies, such as the expert system, nerve cell network, etc. have been applied to the VD furnace in Steelmaking Plant, Baosteel Branch. These technologies have not only finished tasks of collecting and tracking the field data for the model, but also made dynamic calculation and foreeast of the refining temperature trend. It turns out to be the first step to forecast the temperature trend of the whole steel series. Just clicking a picture on the screen, customers at the field, can look into the trend of changes in temperature in the whole VD furnace process.
