Beschreibung
Zusammenfassung:	The invention relates to a TRT static blade control device which comprises a control valve, a control valve servo controller, a control valve electro-hydraulic servo valve, a static blade position sensor and a TRT unit control system. According to the TRT stationary blade control device, the opening degree of the TRT stationary blade can be effectively limited in a safe and efficient area, meanwhile, the safety and stability of the TRT stationary blade on blast furnace top pressure control are not affected, and the core of the TRT stationary blade control device is to improve the TRT power generation efficiency and prolong the service life of the TRT blade; the control loop of the TRT stationary blade control device can be perfectly fused with an existing blast furnace top pressure PID control loop, the TRT stationary blade control loop is only in an online monitoring state when the TRT stationary blade operates in a safe and efficient area, and the TRT stationary blade control loop can act in time only when
