For example, be 1234567890 with the steel reel number of steel, band steel detected when determining in step 205 at the 3rd step rate place, and determine that in step 203 execution step 206 is displaced to the steel reel number 1234567890 with steel the 3rd subpool territory of the 7th storage area from the second subpool territory of the 7th storage area in the time that second step rate also detects band steel.
In the case, in step 120, call the steel reel number in the 3rd subpool territory of the 7th storage area, belt steel surface is carried out to the spray printing of steel reel number.
Should be appreciated that, the quantity of step rate is not limited to three, can be also other quantity.For example, step rate can comprise that N(N is greater than 1 natural number) individual step rate, the 7th storage area comprises N sub-storage area.For adjacent any two step rates (for example, R(R be more than or equal to 1 and be less than the natural number of N) individual step rate and R+1 step rate), band steel detected when determining at R step rate place, and determine while band steel being detected at R+1 the step rate place adjacent with R step rate, steel reel number is displaced to R+1 subpool territory from R subpool territory.
Can follow the tracks of exactly the band steel of coiling area in the method for the coiling area track band steel of hot continuous rolling production line according to an embodiment of the invention, thereby make the steel reel number of belt steel surface spray printing in kind accurately corresponding with band steel.Like this, can effectively improve the qualification rate with steel that coiling area is produced.
Although specifically shown with reference to its exemplary embodiment and described the present invention, but it should be appreciated by those skilled in the art, in the case of not departing from the spirit and scope of the present invention that claim limits, can carry out the various changes in form and details to it.
