摘　　要：为解决烧结矿生产控制过程的大滞后难题,提升烧结成品矿的品质。采用中子活化在线元素分析技术作为实时在线检测手段,提前预测烧结矿的碱度指标,运用比例控制算法,自动控制熔剂仓实时下料量,实现烧结矿碱度的闭环自动控制,提升烧结矿的碱度稳定率。国内2个烧结厂采用碱度自动控制之后碱度合格率分别提升了6.71%和8.73%,证明烧结碱度自动控制技术具有理想的实用效果。In order to solve the problem of large lag in sinter production control process and improve the quality of sinter products,the neutron activation on-line element analysis technology is used as the real-time on-line detection method,the basicity index of sinter is predicted in advance,and the proportion control algorithm is used to automatically control the real-time discharge of flux silo,so as to realize the closed-loop automatic control of sinter basicity and improve the basicity stability of sinter.After the adoption of automatic control of alkalinity in two domestic sintering plants,the qualified rate of alkalinity has been increased by 6.71%and 8.73%respectively,which proves that the automatic control technology of sintering alkalinity has an ideal practical effect.
