一、概述工业炉窑是冶金工业的能耗大户。多年来很多科技工作者都致力于工业炉窑自动控制的研究,努力降低能耗,提高自动化水平。随着微型计算机技术的迅速发展,各种类型的智能仪表和微机控制系统纷纷问世,并日益广泛地应用于工业炉窑控制的各个方面。对于均热炉、加热炉等工业炉窑的燃烧控制,目前虽有许多单回路调节器、集散系统、工业控制机可供选择,但使用起来某些方面尚不尽人意。单回路调节器编程简单,操作方便,但难以随心所欲地编制较复杂的程序,如优化控制程序等。许多进口的集散 First, an overview Industrial furnace is a large energy consumption of metallurgical industry. Over the years many scientists are committed to the industrial furnace automatic control of the study, and strive to reduce energy consumption and improve automation level. With the rapid development of microcomputer technology, various types of smart meters and microcomputer control systems have come out one after another, and are increasingly used in various aspects of industrial furnace control. For soaking furnace, furnace and other industrial furnace combustion control, although many single-loop regulator, distribution system, industrial control machine to choose from, but some aspects of the use is not satisfactory. Single-loop regulator programming is simple, easy to operate, but difficult to arbitrarily compiled more complex procedures, such as optimizing control procedures. Many imported distribution
