The fused magnesia furnace is a key equipment for the production of high performance refractory material, fused magnesia. Its production process has such comprehensive complication as strong coupling, nonlinearity and large time delay. In order to solve the problem of engineering verification of its intelligent optimization control technology, The intelligent optimization control simulation platform of the fused magnesia furnace was established. The experimental platform consists of a set of optimization and basic loop control system (PLC), instrumentation and actuators of the virtual device and simulated on-site melting magnesium furnace object computer components. On the object computer, through the data exchange between MATLAB and dotNet programming platform, it can effectively simulate the input and output characteristics of the fused magnesia furnace. All the process signals from this experimental platform simulate the industrial site. The experimental results show that it can effectively verify the control performance of the intelligent optimal control system of the fused magnesia furnace from an engineering point of view.
