摘要
烧结终点提前预报对于稳定终点,进而提高烧结矿强度和产量、降低能耗有重要意义。为解决烧结过程大滞后环节和烧结终点难以测量的困难,文章介绍了烧结终点的软测量方法;提出了一个新的预报参数——风箱废气温度曲线拐点;将BP神经网络应用于烧结终点的预报,实现了准确地预报烧结终点的状态和生产操作指导。
The on- line measure and prediction of burning through point （BTP） in sintering process is significant to optimize operation which aims improving the strength and yield , In order to overcome the long time delay and Sinter burning Through Point of Sinter Process, The present paper describes a soft- measurement method of BTP and proposes a new predictive parameter ,the mathematics inflexion point of waste gas temperature curve in the middle of the strand. Prediction for BTP with back propagation artificial neural network model, The proposed predict can be used to predict future value of BTP and to help operator to adjust sinter process.
