Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structured flowchart for control system one preferred embodiment with steel of the present utility model.
Embodiment
To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of for the control system with steel, comprise oil storage tank, controller, electric heater, temperature measurement component, man-machine interface, PLC analog quantity assembly, frequency converter and centrifugal pump, described electric heater is connected to the below of oil storage tank and controller, described temperature measurement component carries out communication with described oil storage tank and controller respectively, described PLC analog quantity assembly carries out communication by frequency converter and described centrifugal pump, and described man-machine interface is carried out communication with described temperature measurement component, PLC analog quantity assembly and electric heater respectively.
In above-mentioned, described electric heater is three groups of electric heaters, and three groups of described electric heaters connect into star-like, and wherein, every group of electrically heated power is 6KW.Described controller is three-phase controllable silicon controller, and described temperature measurement component output 4-20Ma current signal is given described controller.
One, oil temperature control
Install PT100 thermal resistance additional at oil storage tank, for Measurement accuracy oil temperature, three groups of electric heaters are equipped with in oil storage tank bottom, every group of heating power 6KW, 18 kilowatts of total heating powers, three groups of electric heaters connect into star-like, connect and controller below, temperature measurement signal is connected to S7-300PLC temperature measurement component (FM355-2), and assembly output 4-20Ma current signal is to controller, adjustable continuously to ensure heating power.Realize temperature closed loop control by the PID control program of temperature control component internal again.Design temperature can arrange flexibly in man-machine interface, and to meet different flattening process requirements, meanwhile, the actual temperature of oil can show in man-machine interface.
If oil temperature raises, just automatically start automatic heat radiation, oil temperature is controlled in the scope needing, so just avoid being difficult to clean because excess Temperature oil carbon forms factice on the surface of steel band, if oil temperature is too low, also can automatically start Automatic-heating, so just meet the activity requirement of different steel strip surface
