Description
Technical field
The present invention relates to a kind of hot cold rolling production technical field, and in particular to fabrication evaluation point on a kind of hot rolling mill production line
Coil of strip start over time obtaining method.
Background technology
Since hot cold-rolling process production line distance is very long, and the time that starts over of coil of strip, (steel coil head passed through a certain work
The time of position and coil of strip afterbody pass through the time of a certain station) often there was only production line head (uncoiler) or production line afterbody
Track on (coiling machine), and do not tracked in production line central region.
Usually, needed according to production, it is necessary to which obtain coil of strip (from head to afterbody) passes through each technique in process of production
Test point is (such as：Calibrator, tensometer, thermometer etc.) time, according to this obtained time range, (steel coil head is by each
The time of test point passes through the time of each test point to coil of strip afterbody), one group is obtained from real-time data base and is arranged in temporal sequence
The data value of row, the data value that this group arranges in temporal sequence are exactly the corresponding process parameter value of its in production process of steel coil.
This group of data value can be shown in a manner of curve in visualization system, the feature of corresponding coil of strip can also be calculated (most
Big value, minimum value, average value and standard deviation), so as to carry out quality analysis and judgement.
At this stage, obtain coil of strip number approach be in coiling machine or uncoiler, be exactly steel coil head one enter coiling machine or
After uncoiler, the new coil of strip ID of system update one, and record this time.But this time, which is coil of strip, reaches coiling machine
Or the time of uncoiler, and the coil of strip of our demands be by the time of each fabrication evaluation point before coiling machine or uncoiler can not
Directly obtain.The time that starts over that coiling machine is generally added and subtracted by executeaaafunction obtains, inaccurate, leads to not to coil of strip
Quality analysis and judgement effectively carry out.

Calculate backward and judge that coil of strip starts over the time by the coil of strip of corresponding fabrication evaluation point, but due to production line head-tail and each work
The distance of skill test point is relatively far away from, on the one hand, the set amount for there are the production line of kink, considering kink is different and kink
Front and rear coil of strip speed is different, and production line head-tail and the distance of each fabrication evaluation point are more remote, and the kink quantity being related to is more, meter
It is bigger to calculate error；On the other hand, since coil of strip is in tensioning state in production line, there is each section of coil of strip elongation percentage in production line
Difference, also has a certain impact for calculation error, and production line head-tail and the distance of each fabrication evaluation point are more remote, calculation error
It is bigger.In the present embodiment, since weld seam detection point is located at hot rolling mill production line central region, with the distance of each fabrication evaluation point compared with
Closely, thus obtain result data accuracy higher.
Further, such as Fig. 1, in step 1, the acquisition methods of the T1 include：
Ts between at the beginning of the coil of strip is obtained by uncoiler or coiling machine, and judge that the Ts is the corresponding uncoiling
Machine still corresponds to the coiling machine, that is, judging above-mentioned Ts is opened between coil of strip passes through at the beginning of uncoiler or by coiling machine
Begin the time；
If the Ts corresponds to the uncoiler, the T1 touches for first weld seam of the weld seam detection point after the Ts
The time is sent out, i.e., searches first weld seam triggered time backward on the basis of the Ts times；
If the Ts corresponds to the coiling machine, the T1 be the Ts before first weld seam triggered time, i.e., with
First weld seam triggered time is searched on the basis of the Ts times backward.
The above-mentioned weld seam triggered time is the time that weld seam detection point detects weld seam on coil of strip.
Correspondingly, in step 1, the acquisition methods of the T1 ' can be identical with the acquisition methods of above-mentioned T1, and specifically, it is wrapped
Include：
The coil of strip is obtained by uncoiler or the end time Te of coiling machine, and judges that the Te is the corresponding uncoiling
Machine still corresponds to the coiling machine；
