摘 要
球团生产工艺的概念，球团生产工艺是一种提炼球团矿的生产工艺，球团与
烧结是钢铁冶炼行业中作为提铁矿石的两种常用工艺。球团矿就是把细磨铁精矿
粉或其他含铁粉料添加少量添加剂混合后，在加水润湿的条件下，通过造球机滚
动成球,再经过干燥焙烧，固结成具有一定强度和冶金性能球形含铁原料。本文
介绍了 PLC 的基本结构和工作原理，西门子 S7-300/400 系列 PLC 的硬件结构、
指令系统、编程方式以及 STEP7 软件的使用。通过这些知识，对球团生产工艺
中的供料系统进行 PLC 控制系统设计，仿真调试，介绍了 PLC 硬件组态及软件
编程的过程，最后应用仿真软件 PLCSIM，对程序进行调试。
关键词：球团生产工艺、PLC、编程，调试
Abstract
The concept of the pellet production process, the pellet production process is
refining the production process of the pellets, pelletizing and sintering are two
commonly used process of iron and steel smelting industry as mentioned in the iron
ore. pelletizer pellets is finely ground iron ore powder or iron powder to add a small
amount of additives mixed, add water, wetting conditions, rolling into a ball, then
after dry roasting, solid form with a certain intensity and metallurgical properties of
spherical iron materials. This article describes the basic structure and working
principle of the PLC, the use of the Siemens S7-300/400 series PLC's hardware
architecture, instruction set, programming and STEP7 software. Through this
knowledge, the feeding system in the pellet production process of the PLC control
system design, simulation, debugging, introduced the process of the PLC hardware
configuration and software programming, the PLCSIM of the last application of
simulation software, the program for debugging.
Keywords：Pellet production process、PLC、programming、Debugging
