摘　　要：针对烧结厂所用原料来源杂、成分波动大,给烧结矿的TFe和SiO2稳定率带来不利影响问题,介绍了混匀料场混匀配料的工艺流程、自动控制系统的原理组成、功能及其自动配料的实现。自动化控制系统在混匀料场投运以来,经过几年的实践使用,成功完成对烧结系统每月约40～50万t的原料供配任务,提高了配料准确性,年效益约为250万元。sintering plant miscellaneous sources of materials used, composition fluctuations, to sinter TFe and SiO2 rate stability brought about adverse effects on the market blending material blending ingredients process, the principle of automatic control system components, function and the realization of automated batching. Control System in the field brake blending material has been put into operation, after several years of practice to use the successful completion of the sintering system 40-50 million t per month of raw materials for distribution tasks, phone calls and improve the accuracy of ingredients, effectiveness, about 2.5 million yuan.
