退火炉自动测控系统设计
摘 要
本文是基于罩式退火炉的结构及退火原理而设计的一套罩式退火炉自动测控系统，主要包括炉膛温度控制、炉膛压力控制、燃料压力控制和冷却器排水温度控制。
罩式退火炉退火处理是冷轧带钢的一个重要环节，其作用是消除加工硬化的现象，使晶粒均匀和组织稳定，而罩式退火炉又有多种形式，本文只对目前常用的氮氢型保护气体单垛式紧卷罩式退火炉的自动测控系统进行说明。从冷轧带钢退火工艺、罩式退火炉的工作原理、罩式退火炉的工艺参数到罩式退火炉的退火程序都作了详细的说明，并列举目前常用的控制系统作参考。此次设计的测控系统主要用到DDZ－Ⅲ型仪表，本文用组态王设计了上位机监控程序，用CAD设计了罩式退火炉自动测控系统图，并对各个系统进行了详细介绍。

Annealing Furnace Automatic Monitoring and
Control System Design
Abstract
This article is based on the Bell-type annealing furnace and annealing the structure of a set of principles designed hood-type annealing furnace automatic monitoring and control system, including the furnace temperature control, chamber pressure control, fuel pressure control and drainage cooler temperature control.
Bell-type annealing furnace annealing of cold rolled strip is an important link, and its role is to eliminate the phenomenon of work-hardening, so that grain uniform and organizational stability, and the hood-type annealing furnace has many forms, the paper only on the current common N-protection hydrogen gas-tight single-stack hood-type annealing furnace volume of automatic monitoring and control system description. Cold-rolled strip from the annealing process, Bell-type annealing furnace of the principle of the Bell-type annealing furnace process parameters to the hood-type annealing furnace annealing process is a detailed description, and cited the current control system commonly used for reference. The design of the monitoring and control system is mainly used DDZ-Ⅲ-type instruments, the paper was designed by Wang configuration PC monitoring program, using CAD design of the Bell-type annealing furnace automatic monitoring system map, and the various systems for the detailed briefing.
