摘要
针对球团原料混合均匀度无法在线检测的问题,采用水分变异系数法来表征混匀度值,并基于失重法的原理,研发了一套球团混匀度在线检测系统,详细阐述了检测系统的结构组成、系统功能及水分检测的控制流程。该系统可与混合机形成闭环控制,从而优化混合机的运行参数,节省能耗和物耗,并将其成功应用于冷钢球团车间,取得了良好的应用效果。
In view of the failure in on-line measurement of pellet raw material mixing uniformity,the water variation coefficient method is used to characterize the mixing uniformity value.Based on the principle of weightlessness method,an on-line measuring system for pellet mixing uniformity is developed.The structure compostion,system function and control flow of the measuring system are described in detail.The system can form a closed-loop control with the vertical mixer,thus the operation parameters of the mixer are optimized,saving energy and material consumption,and it is successfully applied in the cold steel pellet workshop with good application results.
