球团生产线的PLC控制系统设计.doc

共 2 页 第 PAGE 1 页 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 and sintering are the two commonly used technologies for refining iron ore in the steel smelting industry. Pellets is that the fine grinding essence of iron ore or other iron powder mixes a few additives, in the condition of water to wet, through Pelletier rolling into the ball, again after drying roasting, then it become the spherical iron materials with strength and metallurgical properties. This paper introduces the basic structure of PLC 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 these knowledge, we design the feeding system of PLC control system in the production technology of pellets material introduces the PLC hardware configuration and software programming process, finally application simulation software PLCSIM to debug program. Keywords：Pellet production process、PLC、programming 共 2 页 第 PAGE 2 页 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc295329736 1 绪论 PAGEREF _Toc295329736 \h 1 HYPERLINK \l _Toc295329737 1.1 球团工艺的发展状况 PAGEREF _Toc295329737 \h 1 HYPERLINK \l _Toc295329738 1.2 球团工艺简介 PAGEREF _Toc295329738 \h 1 HYPERLINK \l _Toc295329739 1.2.1 球团基础知识 PAGEREF _Toc295329739 \h 1 HYPERLINK \l _Toc295329740 1.2.2 球团生产工艺 PAGEREF _Toc295329740 \h 2 HYPERLINK \l _Toc295329741 1.3 本课题主要内容 PAGEREF _Toc295329741 \h 3 HYPERLINK \l _Toc295329742 2 PLC控制系统设计 PAGEREF _Toc295329742 \h 4 HYPERLINK \l _Toc295329743 2.1 可编程控制器简介 PAGEREF _Toc295329743 \h 4 HYPERLINK \l _Toc295329744 2.1.1 可编程控制器的基本结构 PAGEREF _Toc295329744 \h 4 HYPERLINK \l _Toc295329745 2.1.2 可编程控制器的工作原理 PAG
