Description
Technical field
The present invention relates to metal stock production fields, in particular to a kind of tank level control system and method.
Background technique
In continuously casting production, the liquid level of the metal belt in the condition of high temperature is carried out automatically controlling, can be made
Crystallizer inner metal liquid position height is relatively stable, effectively reduces or eliminates the surface defects such as coarse-grain layer, pile displacement, make ingot casting surface
It is as flat and smooth as possible, the defects of reducing ingot casting thick poor, internal shrinkage, improve the quality of slab.
Realize the automatic control of liquid level premise is that automatic, continuous, accurate, reliable, economic acquisition liquid level is high
Degree evidence carries out closed-loop control to liquid level by automatic Control Systems of Liquids Height.So having during continuous casting of metal
The liquid-level detecting method of effect and reliable liquid level data are to realize the premise of liquid automatic control.
Traditional metal bath surface height detection method is divided into: contact type measurement and non-contact measurement.
Contact measurement method generally uses liquidometer, specifically has: floating ball lever meter, magnetic double level gauge, ultrasonic solution
Position meter, capacitance level gauge etc..
Contactless measurement generally uses: calculating method, actinobolia, laser method.
One of calculating method is to inject the difference of flow and output flow according to crystallizer, then be scaled liquid level height value；
The two of calculating method are the weight change value of crystallizer entirety to be detected with weight sensor, then be scaled liquid level height value.
Actinobolia includes: to penetrate source type, infrared type, vortex patern, electromagnetic type.It penetrates source type and infrared type actinobolia and passes through ray pair
Metal bath surface reflects to obtain the elevation information of metal bath surface, and vortex patern and electromagnetic type actinobolia pass through to electric flux and magnetic flux
Amount changes to obtain the elevation information value of metal bath surface.
Laser method captures the image of metal bath surface and crystallizer inner wall intersection using sensor, records the intersection of different images
Position, and then metal bath surface height value is converted into, to detect and control metal liquid level height.
For overlength small bore metal pipe billet product, the volume of crystallization chamber is small, and liquid storage holds indoor molten metal
The fluctuation of face height is particularly significant on the influence of its quality of item, and the above traditional measurement liquid level method has respectively distinctive lack
Point, it is specific as follows.2, the objective disadvantage of the prior art:
(1) contact measurement method, floating ball lever meter, magnetic double level gauge, ultrasonic level gage, capacitance type liquid level are used
The measurement body such as meter and molten metal contacts, measurement body deform because of the hot baking of high temperature, toast damage, molten metal bonding, foreign matter
The factors such as intrusion, often will appear failure.
(2) Foundry Production is to remove the harmful components such as S, P and prevent metal from aoxidizing, and needs continuously to being added in crystallizer
Covering slag keeps the thickness of correct covering slag and is orderly distributed that slab quality can be effectively improved, because of covering slag weight change
It influences, and for high-temperature metal solution, for a long time, stable, accurately measuring its flow, there are many difficulties, with this to liquid
Position height value is obtained using calculating method, and in practical application there are serious shortcomings, the error that liquid level calculates is big；It is especially heavy
Want, it is this by weight based on method, be for calculating metal belt liquid level in static container.It is right
For the crystallization apparatus of continuous shaking [crystallization apparatus can vibrate], the variation of essence is had occurred in use condition.Continuous vibration
Reciprocal relative motion occurring always between continuous billet casting in the process of work for dynamic crystallization apparatus, between two persons both
There are the acceleration forces of raising and lowering, more there is frictional force between the two.This frictional force is unstable, size change
Change without rule, this situation certainly will lead to the failure of weight calculating method.
(3) in continuous casting production process, with the decline of casting later period metal bath surface, due to by deflecting force of the earth (Coriolis
Power) effect, can metal bath surface generate conflux vortex, measurement result of the conflux vortex for vortex patern and electromagnetic type actinobolia
Serious interference is generated, and high speed conflux vortex generates greatly impact to peripheral electromagnetic field, influences measurement result, leads when serious
Cause the accidents such as metal liquid spilling or bleed-out.
(4) use penetrates source type actinobolia measurement liquid level and utilizes scintillation crystal reception device using isotope radiographic source
The ray with metal bath surface height change is received, thus detect liquid level, but this method fatal defects are that have ray radiation,
The health of worker is endangered, working environment is severe, should not use.
(5) infrared type actinobolia is suitable for unlimited pouring type when being not added covering slag, and vulnerable to shadows such as steam, smog
It rings, this mode seldom uses.
(6) liquid level is measured using laser method, made since lubricating oil etc. is added in continuous casting process of billet withdrawal into crystallizer
For lubricant, lubricating oil immerses metal bath surface from crystallizer side, and burns on metal bath surface, generates flame and smog, fire
The brightness and metal bath surface brightness of flame are close, so that the intersection of metal bath surface and crystallizer inner wall is difficult to differentiate；Smog is in black
And by part or all of image masking, this will lead to false liquid level image, so that the measurement result of metal bath surface height generates
Greatly fluctuation, causes computer that cannot provide correct control amount, and casting quality and the full-automatic continuous casting for influencing metal base are raw
It produces.
Automatic, accurate, reliable measurements are carried out to the high-temperature metal solution liquid level in the crystallizer of continuous shaking, are high temperature gold
Belong to solution tank level control system and accurate data is provided, realize effective control of metal belt liquid level, is to realize overlength small bore gold
The key link for belonging to the serialization of pipe, automation, intelligent Foundry Production, be full-automatic vertical continuous casting equipment for a long time with
Come the problem not yet thoroughly solved.
