Initial plate shape be Ws=360mm, Ps=300mm, Hs=10mm, Ls=300mm, the speed of service of furnace roller is 100m/min,
The temperature in continuous annealing furnace area is 740 DEG C, using the dynamic operation phantom for obtaining, you can obtain the horizontal sideslip equation of strip steel
X=A2+(A1-A2)/(1+exp((y-y0)/A3)) coefficient y0=-3500.8, A1=135, A2=-4.99, A3=1092.4.

Determine that one presets horizontal running deviation value；Based on sideslip equation of locus, calculate the horizontal running deviation value in strip steel reach it is pre-
If the first length that laterally strip steel runs on furnace roller during running deviation value；After strip steel enters continuous annealing furnace area, in strip steel in stove
During the first length run on roller, the horizontal sideslip of strip steel is corrected.
In specific implementation process, the distance (RunDistance) run on furnace roller according to strip steel can be with dynamic realtime
The displacement (OffCentering) of the horizontal sideslip of strip steel is obtained, in order that deviation correcting device completes reverse accordingly to strip steel in stove
Correction, needs to preset horizontal running deviation value to deviation correcting device setting one.As shown in figure 9, to preset horizontal running deviation value as -10.26mm
As a example by, it is 1500mm to calculate the length (i.e. the first length) that corresponding strip steel runs on furnace roller, then in strip steel on furnace roller
After operation 1500mm (now the horizontal running deviation value of strip steel is -10.26mm), then the horizontal sideslip of strip steel is corrected, correction dress
The correction target put then is set as-(- 10.26)=10.26mm.In addition, it can also be 0 that this presets horizontal running deviation value, from
And the horizontal sideslip of strip steel is corrected in real time.
In the present embodiment, by the horizontal sideslip equation of locus of strip steel, carry out sideslip and estimate, and then adopt deviation correcting device

Change model；
Coupling submodule, for by the initial plate shape parameterized model of the Deformation Parameters model of the furnace roller and the strip steel
Coupled, obtained the dynamic operation phantom of the strip steel.
9. system as claimed in claim 7, it is characterised in that the acquisition module, specifically for：
Based on the dynamic operation phantom, the corresponding sideslip equation of locus x=A of the strip steel is determined2+(A1-A2)/(1+
exp((y-y0)/A3)) coefficient A1、A2、A3And y0；Wherein, x is the strip steel horizontal running deviation value on furnace roller, and y is the band
The length that steel runs on furnace roller.
10. the system as described in claim 7~9 is arbitrary, it is characterised in that the correction module, including：
Determination sub-module, for determining that one presets horizontal running deviation value；
Calculating sub module, for based on the sideslip equation of locus, calculating described in reaching in the horizontal running deviation value of the strip steel
The first length that the strip steel runs on furnace roller when presetting horizontal running deviation value；
Correction submodule, for run on furnace roller in the strip steel first length when, the horizontal race to the strip steel
It is biased capable correction.
