摘　　要：通过数据分析确定球团焙烧因素的相关性,制定模糊控制规则,结合PID算法实现焙烧温度智能化调节。该控温方法有效解决球团焙烧过程随时间和生产的热传导模型不恒定、迟滞性强的控制问题,在连续生产情况下各个焙烧环节温控精度±10℃,球团矿转鼓指数由95.38%(+6.3 mm)提高到97.89%(+6.3 mm),抗压强度由2006 N/个提高到3149 N/个。Through data analysis, the correlation of pellet roasting factors is determined, fuzzy control rules are formulated, and PID algorithm is combined to realize intelligent regulation of roasting temperature. The temperature control method effectively solves the control problems of unsteady heat conduction model and strong hysteresis of pellet roasting process with time and production. Under the condition of continuous production, the temperature control accuracy of each roasting link is ± 10 ℃, the pellet drum index is increased from 95.38%(+6.3 mm)to 97.89%(+6.3 mm), and the compressive strength is increased from 2 006(N/piece)to 3 149(N/piece).
