摘 要
全氢罩式退火炉是冷轧带钢退火的一种主要设备，它对提高产品质量起着十分重要的作用。目前该设备国内依靠引进，特别是其控制系统完全由国外提供。本文对全氢罩式退火炉的退火工艺、设备组成、国内外全氢罩式退火炉各种控制系统的特点进行了深入的研究，针对全氢罩式退火炉的工艺流程，对基础控制系统的控制范围、硬件结构、控制功能的软件实现等进行了详细研究和设计，开发了一套全氢罩式退火炉的温度控制系统。
全氢罩式退火炉控制系统分为流程控制和过程量监测两部分，由于其使用易爆的氢气作为保护气，因此对控制系统的要求是安全、可靠。本文在开发该控制系统时，硬件配置上充分考虑了系统的可靠性和经济性要求，软件设计上采用模块化设计思想，将程序按设备管理、过程管理和集中输出分类，并在程序中设置了多重安全措施，保证了应用程序的运行安全和可靠性。
通过本研究，可以实现全氢罩式退火炉基础控制统的国产化，这对于全氢罩式炉成套设备和技术的国产化具有重要的意义。

ABSTRACT
Hydrogen annealing furnace is a type of equipment for cold rolling strip annealing，and this is very important for improving strip’s quality。In our country almost all of furnaces are imported at present，and its control system is offered wholly by foreigners。In this paper the technology and equipment of hydrogen annealing furnace as well as its control system in many domestic and foreign factories has been studied in deal。According to annealing furnace’s technological process，a base control system，including control content，hardware framework and control function software has been designed。
The hydrogen annealing furnace base control system consists of process control and process parameters monitoring。Because the furnace is full of explosive hydrogen，its control system should be very safe and reliable。During the study and developing of the control system，the whole system’s reliability and economy are considered fully on hardware disposition，and model block is used on software design。The client software consists of equipment management，process management and centralized output，and many kind of safety measure are set up in the software，which ensures the software running safely。
By means of this study，it is possible to develop hydrogen annealing furnace base control system by ourselves，which is very important for the equipment and technology of annealing furnace been made in china。
KEYWORDS：hydrogen annealing furnace，process control，temperature control
