Processor 20 first carries out simple image preprocessing after receiving this frame slab two dimensional image, then carries out judgement slab
The foreign matter area change of body surface.Firstly, the wheel of slab ontology is extracted from this frame slab two dimensional image by image segmentation
Exterior feature identifies that the surface of slab ontology in this frame slab two dimensional image with the presence or absence of foreign matter region, obtains the first recognition result.
Specifically, then being mentioned using image segmentation since slab ontology and the foreign matter on its surface have different gray values
The slab ontology in this frame slab two dimensional image is taken, covering slag that may be present on slab body surface or iron scale etc. is different
Object is drawn a circle to approve, and can distinguish slab ontology and foreign matter region, to identify slab ontology in this frame slab two dimensional image
Surface whether there is foreign matter region.
Specifically, find that foreign matter is indicated with regard to the boundary point immediately to foreign matter region on this frame slab two dimensional image,
In the specific implementation process, discovery may be the collected arbitrary frame of steel-making continuous casting there are the slab two dimensional image in foreign matter region.
In turn, when the first recognition result, which is, is, judge foreign matter region from this frame slab two dimensional image to next frame base two
Whether dimension image increases, and obtains the first judging result.
Specifically, the first recognition result is when showing to find foreign matter on this frame slab two dimensional image, then to record the foreign matter area
Pixel number m of the domain in this frame slab two dimensional image, to be characterized on this frame slab two dimensional image shared by foreign matter region
Area.Reception next frame slab two dimensional image is then waited for record same different when receiving the next frame slab two dimensional image
Pixel number n of the object area in the next frame slab two dimensional image, to characterize foreign matter region in the next frame slab two
Tie up foreign matter region occupied area on image.To have recorded the area of same foreign matter in adjacent two frames slab two dimensional image respectively
Size.If pixel number n is greater than pixel number m, show that the area in foreign matter region increases;If pixel number n
Equal to pixel number m, then show that the area in foreign matter region is constant;If pixel number n is less than pixel number m, table
The area in bright foreign matter region reduces.
For example, if finding foreign matter on the 10th frame slab two dimensional image, then the foreign matter region is recorded in the 10th frame
Pixel number m in slab two dimensional image then waits for receiving the 11st frame slab two dimensional image, is receiving the 11st frame slab
When two dimensional image, then pixel number n of the foreign matter region in the 11st frame slab two dimensional image is recorded.(n-m) is calculated, is sentenced
Whether disconnected (n-m) is greater than zero.If (n-m) is greater than zero, the pixel quantity in foreign matter region increases, and shows foreign matter region
Area increases;If (n-m) is equal to 0, the pixel quantity in foreign matter region does not change, and shows that the area in foreign matter region is constant,
If (n-m), less than 0, the pixel quantity in foreign matter region is reduced, show that the area in foreign matter region reduces.Certainly, specific real
During applying, can also directly compared pixels point number m and pixel number n size come determine foreign matter region be increase, subtract
It is any in small or constant.

The Temperature Distribution of copper sheet.Specifically, typical temperature signal is divided into normal, table in two rows thermocouple crystallizer in copper sheet
4 kinds of planar defect, bonding steel leakage and corner bleed-out modes.
Wherein, in the normal mode, the detection of 2 heat extraction galvanic couples up and down in normal productive process, in copper plate of crystallizer
To temperature value should be 2 more straight curves, only small fluctuation.
Wherein, in surface defect mode, the generation of this mode is involved in since covering slag melts bad or slag item
Meniscus affects the surface quality of slab.If also will appear this mode in addition, longitudinal crack occurs for solidified shell.The mould
The temperature curve of formula is characterized in that the temperature waveform of 2 heat extraction galvanic couples has a trough, and the appearance of trough may with crystallizer and
The air gap formed between solidified shell is related.Decline in addition, melting bad clinker with green shell, is slid onto the position of embedded thermocouple
It sets, it is also possible to will form a trough.When there is such case, it often will lead to some surface quality problems.The biography of Longitudinal Surface Cracks

It not will lead to bleed-out, it is a kind of surface defect, be may be incorporated into quality problems, to be produced when necessary by subsequent handling to slab
Product are handled.
Wherein, in bonding steel leakage mode, when bonding generation, tearing point when the location of thermocouple by generally can
There is this temperature model.Bonding occur when, slab tearing point not only propagates along longitudinal direction, and bonding steel leakage most distinct feature is that
The decrease speed for bonding hot spot is lower than drawing speed, and green shell fracture can make temperature measured by thermocouple substantially after molten steel exudation
Rise, and as the decline measured temperature of bonding hot spot (breaking point) will appear an obvious falling, when hot spot passes through lower row
It just will appear the phenomenon that lower row's temperature is more than upper row's temperature when thermocouple.
It wherein, is that cooling is too strong in the corner of crystallizer in the reason of corner bleed-out mode, corner bleed-out pattern formation,
Solidified shell is shunk so that forming gap between green shell and crystallizer, and subsequent molten steel overflows across the meniscus formed in advance, into this
It is solidified behind a little gaps, resistance of billet withdrawal is caused to increase, it is unsmooth green shell decline occur, is likely to form drawing crack at this position.Drawing crack point warp
When crossing the thermocouple for being embedded in crystallizer corner, it often will appear the temperature signal of this mode.This Frequent Accidents life is being replaced
The situation that tundish, mold liquid level are lower and pulling rate is lower, at this moment copper plate of crystallizer is cooling very well, and the slab solidified is at angle
Portion forms gap, and at this time because drawing speed variation or other reasons lead to liquid level fluctuation of crystallizer, subsequent molten steel overflows across meniscus
When just enter the gap.In addition, covering slag enters corner when on-line control crystallizer width, such gap also will form.?
Corner bleed-out to hang based on bleed-out, it is typical hang bleed-out be characterized in heat extraction galvanic couple due to closer from damaged green shell,
Being thinned significantly by molten steel exudation or initial solidification shell, which influences temperature, obviously rises, and then since green shell is thinned at lower heat extraction galvanic couple
Now apparent temperature rises, but because molten steel does not ooze out, so that its temperature and being less than the thermometric value of heat extraction galvanic couple.Lobe and viscous
The main difference of junction leakage steel is spread speed, and the spread speed of lobe is much higher than drawing speed, the spread speed of slag inclusion with
Drawing speed is consistent, and bonds spread speed is usually normal pulling rate 50%~80%, this typical difference is conducive to me
Judge the generation of slag inclusion, lobe and bonding steel leakage.
So the method in the present embodiment, processor 20 can according to the temperature curve for the thermocouple being arranged on copper sheet,
Determine whether bleed-out, obtains a prediction result.
Further, processing parameter detection module further includes crystallizer mean heat flux, according to the meter of heat flow density
Formula is calculated, is obtained by detection crystallizer cooling water flow and cooling water outlet and inlet temperature difference.Due to being poured in pulling rate stabilization
In the case where casting, crystallizer mean heat flux value is in a smoothly fluctuation, when there is bleed-out, crystallizer heat flow density
Value will appear decline, so, bleed-out can be determined whether according to the detection of crystallizer mean heat flux, obtain a bleed-out
Testing result.
Further, processing parameter detection module further includes level detection sensors device, level detection sensors device setting
Inside crystallizer, for detecting the liquid level of the molten steel inside crystallizer.Due under normal circumstances, molten steel in crystallizer
Liquid level need to maintain the 75%~90% of crystallizer height, when there is bleed-out, liquid level can occur sharply to decline, institute
Can determine whether bleed-out according to liquid level, obtain the testing result of a bleed-out.
