摘　　要：料流调节阀是高炉无料钟炉顶关键设备之一,其控制效果的好坏直接影响高炉的稳定运行。由于料流调节阀运行速度快、控制精度要求高,加之传统料流调节阀的驱动和控制系统存在一定问题等诸多方面的原因,长期以来实现对料流调节阀的精确、可靠控制一直是一个难题。本文对传统的料流调节阀的控制原理、策略、控制效果及存在的问题等进行了分析和总结。作为改进和创新,介绍一种新型由液压伺服阀驱动的料流阀调节系统,简述该料流调节阀系统的构成和控制原理。最后对两种控制系统的性能进行了比较,说明了新型料流调节阀的优点和控制效果。Material flow regulating valve of bell-less top is one of key equipment for blast furnace.Its control effect influence stable operation of blast furnace directly.Because there are some problems in drive and control system of traditional material flow regulating valve,accurate and reliable control of the valve is difficult to achieve for a long time.Control principle,method,effect and problems of traditional material flow regulating valve are analyzed and summarized.As an innovation,a new type of material flow regulating system which is driven by servo hydraulic valve is introduced.Its configuration and control principle are described.Through comparison of both control systems,advantages and control effects of new type material flow regulating valve are explained.
