摘　　要：为了提高钢铁冶炼的质量,优化高炉顶压的控制方法。以大中型高炉为研究对象,通过分析高炉的工艺流程及影响炉顶压力的因素,构建了高炉炉顶压力的数学模型。在此基础上探讨了一种基于减压阀组调节的高炉顶压控制策略—跟随比例积分微分(tracking proportion integral differential,T-PID)控制。为验证此数学模型和控制策略的有效性,应用MATLAB/Simulink搭建了系统仿真模型,仿真结果验证了该策略的正确性。将该方法应用于某钢1#高炉顶压控制系统,结果表明高炉顶压波动能控制在±3 kPa,具有良好的效果。In order to improve the quality of iron and steel smelting and optimize the control method of furnace top pressure.Taking large and medium-sized blast furnace as the research object,the mathematical model of blast furnace top pressure was constructed by analyzing the process flow of blast furnace and the factors affecting the top pressure.On this basis,a control strategy of top pressure of blast furnace based on pressure reducing valve group regulation-tracking proportion integral differential(T-PID)control was discussed.In order to verified the effectiveness of the mathematical model and control strategy,and the system simulation model was built by MATLAB/Simulink.The simulation results verify the correctness of the strategy.The method was applied to the top pressure control system of a steel 1#blast furnace.The results show that the top pressure fluctuation can be controlled at about±3 kPa,which has good effect.
