1, each bringing-up section all has electric flow control valve, and at present still can hand-guided;
2, each bringing-up section is equipped with flowmeter;
3, furnace pressure baffle plate is Electronic control.
In addition, native system is also the electrical automation system carrying out " intellectuality accurately controls " for the fired state of large-scale steel rolling heating kiln, this control system integrates " online measuring technique ", " basic combustion control technology ", " fuzzy control technology ", is specially for the upgrading Optimal Control System of original PLC control system.
This system utilizes the real-time atmosphere of multiple combustion zone in kiln to analyze data as control foundation, rely on " Combustion System model ", whole combustion system is changed into " closed loop " control model from original " open loop " control model, and by self-recision function, make the combustion atmosphere in whole kiln be in all the time " optimal combustion state ".
First, native system is built-in with accurate " Mathematical Modeling of oxygen gesture, carbon potential, temperature triadic relation " that pre-set, the arithmetic model of oxygen gesture, carbon potential, temperature triadic relation is the core technology setting up accurately burning, it is the basis to the fuzzy control of heating kiln system implementation, and system can realize controlling the matrixing of heating kiln each section of fired state.
In addition, native system additionally uses heating kiln " optimal combustion operating mode is detected " technology, and so-called " optimal combustion operating mode " refers under the prerequisite meeting basic heating process requirement, fired state when fuel consumption, remaining oxygen simultaneously can be made all to be in minimum; " optimal combustion operating mode is detected " technology utilizes control system and kiln interaction, the optimum posture should made when optimal combustion operating mode according to each combustion zone (valve) in interactive results verification kiln, finds out the valve interactive relationship that can form " optimal combustion operating mode " with this.Finally " intelligent accuracy-control system " is by using " the optimal combustion operating mode " that detect as control basis, realizes accurate Combustion System according to online feedback data and Controlling model.
Finally, technology that native system have employed " dual system redundancy backup ", effectively raise stability and the reliability of system cloud gray model, wherein, " dual system redundancy backup " technology refers to the mutual redundancy technique of original PLC combustion control system and intelligent accuracy-control system.This technology requires for the safety and stability of industrialized production and design, and can automatically switch because of fault or manually switch, to ensure the uninterrupted operation of production line between original PLC system and intelligent accurate system.
In addition, two kinds of modes of having plugged into of the input signal of native system:
