Mathematical Model Construction of Reheating Furnace for Improving Billet Heating Quality
Heating furnaces have important applications in various industries such as chemical engineering and steel.As one of the thermal e-quipment,the heating furnace has the characteristics of hysteresis and time-varying,which greatly affects the heating quality of materials.The quality of billet in the heating process will be affected by many factors such as heating temperature,heating speed and heating time.When de-termining the heating temperature,it is not only necessary to consider the nature of steel,but also to consider the processing requirements,to obtain the best plasticity,improve the output and quality of rolling,effectively reduce energy consumption,reduce equipment wear,and pro-duce high-quality steel products.In this paper,the step-by-step heating furnace for billet heating is taken as the analysis object,and the opti-mal control means of the furnace is analyzed and discussed.First,the structure of the heating furnace and the combustion control system are introduced,then the construction method of the temperature mathematical model of the heating furnace is discussed,and the optimization method is proposed,aiming at improving the effectiveness of the heating furnace in the billet heating process,making it more consistent with the temperature setting requirements of industrial production,and playing an important role in improving the quality of industrial heating and energy saving and consumption reduction.
