Description
Technical field
The present invention relates to metallurgical industry field, be specifically related to be applied to the vibration detection device of bale slag-blanking.
Background technology
In the production run of continuous casting process, molten steel flows into tundish from big bag by the long nozzle protective casing, enters crystallizer through slide gate nozzle again, and the cooling after coagulation becomes the strand in various cross sections.Wherein, slag blanket has the anti-oxidation effect of insulation to the molten steel in big bag and the tundish, yet can cause molten steel to pollute when the slag blanket in the tundish is blocked up, the heat erosion of tundish fire resistive material is increased and the thickness of the remaining slag blanket of increase tundish.Therefore must control from the big slag that wraps tundish and flow, this batch has very important meaning to raising slab quality, increase continuous casting.
Existing multiple at present slag pick-up unit, for example infrared detecting device, induction pick-up unit and ultrasonic detection device etc. down.Slag detection system based on infrared technique can guarantee to begin just to realize accurate, slag detection reliably from tapping process.The following slag of this type systematic through being usually used in converter taphole detects at present; but under continuous casting full guard casting condition; this system can not be applied to wrap greatly the following slag detection of tundish; if this is owing to be used for wrapping greatly the following slag detection of tundish; then must remove the long nozzle protective casing; thereby molten steel can not be blocked in detection; and will cause the secondary oxidation of molten steel like this; therefore infrared detection system generally is not used in the following slag detection of big bag at present, and is mainly used in the following slag detection of converter taphole to ladle.
Induction slag detection system down is considered to more advanced in the world following slag detection system at present, and external existing how tame steelworks adopts this system, and obtains better metallurgical effect and economic benefit.Owing to adopt this type systematic to require big bag is transformed, promptly, imbed coil in big bag bottom, this improvement expenses costliness, and because operating ambient temperature is higher, cause coil to be easy to damage, will change average every month to coil, the sensor of big bag bottom, thereby make use cost higher.
In addition, utilizing ultrasound wave to carry out under the molten steel that slag detects also is a kind of method commonly used.The principle of ultrasonic Detection Method is to utilize in the big bag beam when slag being arranged and the do not have slag difference between ultrasonic emitting, the reflected signal to realize detection to slag.Though this method is to not influence of casting cycle, but since the operating ambient temperature of ultrasonic probe up to 1500 ℃ about, work under bad environment makes that the expense of the manufacturing of this system and use is higher, therefore also is difficult at present extensively promote in commercial Application.
And the initial origin of practice of method for detecting vibration is on-the-spot in the molten steel casting.In casting process, the vibration of the big bag long nozzle protective casing motion arm that veteran veteran worker can experience by casting latter stage changes and judges the slag amount that enters tundish by bag greatly prior to visual observation.A large amount of on-site experiences has proved that also the dregginess in the molten steel that flows in the vibration of big package operation arm and the long nozzle protective casing is closely related.In fact, flow into the process of tundish from big bag at molten steel, the long nozzle protective casing can make the motion arm that is attached thereto produce stronger vibration, and long nozzle protective casing aperture is big more, and the molten steel flow is just big more, and then the vibration of motion arm is strong with regard to Shaoxing opera.Yet; the proportion of slag approximately is 1/3rd of molten steel; it is inevitable variant with the flow vibration that causes of molten steel then to be flowed by slag, therefore, and the situation of change that the vibration by the monitoring motion arm should be able to the interior molten steel flow state of indirect monitoring long nozzle protective casing in theory.
But the vibration situation in the continuous casting process is a more complicated, and often having a lot is not that principal element is as follows by the vibration of the mobile vibration effect motion arm that causes of slag:
First, in casting process, require the molten steel amount of tundish basicly stable (promptly, the molten steel liquid level can not be too high, can not be too low), the aperture that this just requires operating personnel will regulate the slide gate nozzle of ladle according to the molten steel amount in the tundish when the liquid level of tundish is too high, will be turned the aperture of slide gate nozzle down; And cross when low when the tundish liquid level, aperture will be transferred big.This just makes the state of the molten steel in the long nozzle protective casing change thereupon, and this variation also can influence the vibration of motion arm, makes vibration increase/reduce along with the increase of slide gate nozzle aperture/reduce;
The second, in the latter stage of big bag cast, another bag can be smelted good molten steel and be placed on the bale panoramic tables, after last Baogang liquid poured, this Baogang's liquid that place the back will then be poured into a mould.And this process of amplifying bag can be brought impact to whole bale panoramic tables, and this impacts the vibratory impulse that has also caused motion arm simultaneously;
The 3rd, in the bale slag-blanking testing process, operating personnel operate slide plate continually, each operation all will influence the vibration of motion arm and keep a period of time, if following slag at a time when this, then useful signal (promptly descend the vibration of the motion arm that slag causes to change) will be covered, thus influence slag judgement down;
The 4th, the rigidity of execute-in-place arm is big, Heavy Weight, and on hiring a car in the middle of being fixed in, when the vibration transfer that the molten steel in the long nozzle protective casing causes arrives the sensor of motion arm end, the signal of molten steel vibration correspondence is very faint, and basic only remaining the interference vibrated corresponding signal;
In addition, also have some ambient vibrations, artificially vibration and noise in the continuous casting workshop, people's walking vibration etc. on the vibration of the noise during as electric arc furnace smelting, continuous casting workshop steelframe, the middle bag platform, these vibrations or noise all can impact the vibration of motion arm.
Therefore, sensor is directly installed on traditional vibration detection device on the mechanical arm to make and has comprised the information that a large amount of vibration performances that cause with the molten steel vibration have nothing to do in the signal of sensor acquisition, the signal to noise ratio (S/N ratio) of signal that is conveyed to sensor is very low, useful signal be buried in a large amount of garbage signals and Oscillation Amplitude very little.Such signal is carried out signal analysis such as time-domain analysis, frequency-domain analysis, scramble domain analysis, statistical study, wavelet analysis and judge through neural network, can cause very high wrong report rate of failing to report, thereby cause slag alarm rate instability down, can reach more than 80% under the good situation of field condition, have only 70% in the time of bad, this can not satisfy in the general steel mill 95% requirement.
