Fused magnesium furnace is the main equipment for the production of fused magnesia production principle , fused magnesium furnace is submerged arc furnace , a kind of electric arc furnace , electrical characteristics , fused magnesium furnace is a strong nonlinear , time-varying and strong coupling of the controlled object . In the course of their work , power , operating current of rapid change , high energy consumption would grid waveform distortion , voltage flicker , low power factor and cause a variety of adverse effects of the three-phase circuit imbalance . In order to improve product quality, improved fused magnesium furnace automation control technology to reduce energy consumption and the cost of on-site commissioning , to reduce the risk of on-site commissioning , fused magnesium furnace control loop simulation experiment system in the laboratory is important. The support of the National Support Program , relying on the \research and fused magnesium furnace model to establish an experimental platform . This paper carried out the following work : 1 . The design fused magnesia furnace control semi-physical simulation system architecture , including fused magnesium furnace virtual objects , fused magnesium furnace PLC control system, PC monitoring system , touch screen , console . Virtual object software design and development of fused magnesium furnace , fused magnesium furnace virtual object model and algorithm library, parameter setting interface, fused magnesium furnace dynamic model , dynamic simulation software man-machine interface . (3) design and development of a rule-based reasoning method fused magnesium furnace control system control software , including normal control , abnormal control from the furnace control , exhaust control , playing material control and other control procedures . Development the fused magnesia furnace PC monitoring software, including real-time monitoring screen , the historical trend screen . 4 in the experimental study on the simulation system . Including fused magnesium furnace process dynamic modeling experiment , the software system experiment, under normal operating conditions the control loop interference suppression performance experiments . By the experiments to verify the feasibility of the experimental system , the object model can qualitatively reflect the ability of fused magnesium furnace process dynamics and control effectiveness of the algorithm .
