攀钢2#、3#高炉新增热风炉的自动控制简介

攀钢炼铁厂3^#高炉在2006年4月大修时新增4^#热风炉，工艺上要求该炉对2^#、3^#高炉自由切换送风。3^#高炉大修后控制系统采用Ovation系统，该系统是目前世界上先进的DCS系统，具有强大时序控制和模拟量处理功能，为满足复杂的工艺要求，对4^#热风炉的控制采用了2个远程Drop和1个监控站控制模式，对该炉的控制功能得以较好的实现。本文简要介绍了在Ovation系统上对攀钢2^#、3^#高炉新增热风炉的自动控制过程。

AUTOCONTROL OF ADDITIONAL HOT AIR STOVE IN NO.2 AND NO.3 BLAST FURNACES PZH I&S CO.

No. 4 hot air stove was added during major repair of No. 3 blast furnace in April 2006. The process needs that hot air can be conveniently cut over to No. 2 or No. 3 BF. The control system of No. 4 stove is Ovation system after the repair of No. 3 BF. To satisfy complicated process requirement two distant Drop and one monitoring station are made use of in the control of the stove. The function of the control is better. The autocontrol process of the stove on Ovation system is introduced in this paper.
