Description
Technical field
The present invention relates to conticaster system and control method, continuous casting is handled more specifically to one kind
Pour into a mould the autocontrol method and system of channel blockage.
Background technology
Continuous cast mold level control is stable and slab quality control the key of continuous casting, with even
The increasingly strict of the control requirement such as product surface quality and inner clamps debris is cast, logic approach for mold level control
Stability is increasingly paid attention to by everybody, and modern continuous casting crystallizer for plate billet level control typically divides knot
Two parts of brilliant device level detection and automatic flow control, the main flow equipment of level detection is mainly electromagnetic eddy
Formula level detection is mainly the sliding plate hydraulic servo based on Japanese with source detection, automatic control system is penetrated
System automatic flow control and stopper electric cylinder or hydraulic cylinder automatic flow control based on the system of Europe.Due to stopper control
Stream is simple to device structure, favourable to the stability in crystallizer flow field, while reducing a slide plate suction
Gas point, so, stopper rod flow control system is progressively popular at home and abroad at present.
Either sliding plate flow-control or stopper rod flow control, the final purpose that system is set is in certain logical steel
Mold liquid level keeps stable in the continuous casting process of the next tundish of velocity interval.But in actual life
During production, because the cast passage in from tundish to crystallizer is easily by drosses such as alundum (Al2O3)s
Thing blocks and causes the irregular change of channel cross-section, declines flow control stabilizing effect.Using stopper
During automatic flow control, cast passage in be easiest to occur dross cause liquid fluctuating even flow control failure be
Around stopper head and filling pipe end, therefore, substantial amounts of the correlation technique such as resistance to material of anti-caking plugging function, stopper
Argon technology, stopper automatic vibration technology, the obfuscation control of flow control pid parameter or preposition control etc.
Arise at the historic moment, many technologies are widely used in actual production, achieve certain effect.Wherein
The stopper vibration control technology of French SERT companies etc., liquid level pre-compensating technology, filling pipe end, plug
The application such as Argon control technology of the positions such as rod is than wide, and the major function of these technologies is：
Stopper is prevented as far as possible or poured into a mould the dross of passage, blocked；
By controlling compensation, the regular cyclic swing of mold liquid level is reduced.
In fact, stopper vibrotechnique is limited because of the amplification and vibration frequency under normal pouring, Zhi Nengqi
To limited anti-dross effect, and correlation technique in terms of Argon and resistance to material by strand air entrapment,
Field trash etc. is controlled and anti-resistance to material corrode after the limitation failed of flow control can only as a kind of booster action,
It is only used for similar to technologies such as liquid level pre-compensating, fuzzy controls because of casting blank bulging or stopper control machine
A tundish connects in the regular stronger liquid fluctuating that the reasons such as gap that structure have are caused, production process
The irregular unusual fluctuations of liquid level after the middle and later periods of continuous casting process, passage gradually blocks caused stopper
The problems such as aperture increases still can not solve.Flow control device aperture gradually increases after dross is actually occurred,
Fluctuation by a relatively large margin irregular one by one is presented in Mold face.
It is well known that continuous cast mold liquid level unusual fluctuations are strand slag inclusion, the main cause that is mingled with it
One, when cast passage dross arrives certain degree, after flow control system standard-sized sheet, flow control failure, often
The abnormal whole method processing poured can be taken, whole pour of this exception can produce greatly to the logistics of whole steel mill
Interference, also influence casting machine operating efficiency.If finding to start extraordinary wave occur in casting process
Move, and flow control system aperture gradually increases without taking timely measure to continue to pour into a mould, and subsequently pours into a mould
Slab quality is difficult to ensure, the batch such as is also easy to cause the slag inclusion of strand because of liquid fluctuating, is mingled with
Property amount defect, or even bite base because bonding steel leakage accident, field trash occur for the disconnected slag of crystallizer meniscus
Shell and occur bleed-out accident.So, selection continues to pour after cast passage dross, liquid level unusual fluctuations
Note or to pour eventually be the contradiction existed all the time for a pair, but general be all defined by obeying the requirement of process continuity
And continue to produce.
To prevent cast passage dross, block and thus caused liquid fluctuating, in conventional manual stopper
Also there is the operating method of " extrusion rod " during flow control --- it is a kind of by being manually drastically opened and closed stopper
Mode, the dross thing that will be attached to around stopper or filling pipe end is washed out, or is blown using big flow argon gas
The mode for sweeping (stopper Argon or filling pipe end Argon) goes to handle this exception, sometimes also useful two kinds of sides
Formula carries out the way of the cleaning of dross thing together.But because manually-operated normalization is very poor, particularly
These operations under higher pulling rate easily lead to such as crystallizer extension steel suitable for reading, slag, field trash
Bite etc. abnormal, the quality, safety, direct motion of cast can be had a strong impact on；And automatic using stopper
After flow control system, this operation is very big because of the damping of stopper control mechanism, adds the stopper of automatic flow control
Integral type stopper typically is, misoperation is easier to cause stopper to be broken, even if so switching is in one's hands
Work mode also can not almost be implemented to rush clubs work manually.
In addition, to prevent dross around stopper, the stopper of the stopper vibrotechnique of current more use shakes
Dynamic parameter is substantially stationary after the completion of debugging, although can be changed by way of changing parameter and shaken
Dynamic amplitude and frequency, but it is necessary to have the regular hour for modification parameter, it is clear that make this with rushing clubs
Single, instantaneous abnormal operation requirement are not inconsistent.
