摘  要

球团生产主要是提炼球团矿，球团与烧结是钢铁冶炼行业中作为提炼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，固结成为具有一定强度和冶金性能的球型含铁原料。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，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

Abstract

Pellet production main refine pellets, pellets andsintering are the two commonly used technologies for refining iron ore in thesteel smelting industry. Pellets is that the fine grinding essence of iron ore orother iron powder mixes a few additives, in the condition of water to wet, throughPelletier rolling into the ball, again after drying roasting, then it becomethe spherical iron materials with strength and metallurgical properties. Thispaper introduces  the basic structure ofPLC and working principle , the hardware structure, instruction system,programming method of Siemens s7-300 300/400 series PLC ,  and the use of STEP7 software. Through theseknowledge,  we design the feeding systemof PLC control system in the production technology of pellets materialintroduces the PLC hardware configuration and software programming process,finally application simulation software PLCSIM to debug program.

Keywords：Pellet production process、PLC、programming
