| With the rapid development of science and technology production level,the international steel production quality requirements also strictly, especially in somehigh-end technology application is particularly, this makes steel production in the face ofserious problems, including steel of sulfur, phosphorus content of steel the harmfulelements required standards more and more is also high.Facing today’s international development situation, in steel production of moltensteel desulfurization process research become one of the important link, then developmentappeared the molten iron mixing method, injection method, thread feeding method severaldesulfurization process technology, in order to ensure the desulfurization efficiency, underthe premise of how to achieve good effect and economic cost desulfurization low, theactual operation relatively simple also is in the present study factors such as the importantlink.Control system in the molten iron process controller is most widely used fuzzy PIDcontrol system, the fuzzy PID control system has the advantage that it suitable forapplication in more complex control technology in the system, and can meet therequirements for the desulphurization reaction speed, stability conditions of processcontrol system, is the most widely used in industrial production of one of the controlsystem.Based on the background of the first green steel iron, focuses on the first blowparticles desulphurization process this magnesium, describes the technological processand the basic principle of practical significance, and secondly in fuzzy PID control basedon the theory of combining with the actual process using MATLAB simulation tools forthe control system is studied, summarizes the desulphurization process to thedesulphurization performance factors. Using the programmable controller S7-300andMCGS configuration tools to blow particles magnesium the desulphurization controlsystem to realize and debugging, and obtain the better control effect. |
