| description | The invention discloses a pressure equalizing and constant pressure control method for air pressure during hot blast stove replacement, which comprises a signal connection cabinet, the signal connection cabinet adopts a PLC (Programmable Logic Controller) control system, the PLC control system is Siemens 1500 and is used for gathering all blast furnace signals and distributing the signals to corresponding fans, and data switching of the blast furnace and the fans is connected by the PLC control system. The fan only adjusts one set of signals, fan side constant pressure control and hot blast stove side automatic voltage-sharing control can be automatically achieved, oscillation and fluctuation caused by similar PID adjustment control are avoided, loading stability of the fan in the furnace changing period is guaranteed, and meanwhile safety of blast furnace ironmaking is guaranteed.
本发明公开了一种热风炉换炉时风压的均压、定压控制方法，包括信号联络柜，所述信号联络柜采用PLC控制系统，所述PLC控制系统为西门子1500，用于将所有高炉信号汇总，并分配给相应风机，而高炉和风机的数据切换由PLC控制系统进行联络，风机只针对一套信号进行调节， |
