1. , a kind ofly it is characterized in that described method comprises the following step of being carried out by plate shape proofing unit with the contactless method for detecting shape in the steel continuous annealing process:

  • (1) provide some transmitters before the annealing furnace inlet, described transmitter is separately positioned on the middle and dual-side of cross section of delivery direction, measure the band steel and distributing, between two bearing positions of described cross section before the annealing furnace inlet perpendicular to the vertical height on the cross section of its delivery direction;

    (2) calculate the some length distribution of longitudinal region between described bearing position that are parallel to its delivery direction of band steel, wherein, each described longitudinal region calculates according to the vertical height of this zone on described cross section in the length between the described bearing position to be determined;

    (3) calculate the fluctuating quantity of belt steel surface according to described length distribution;

    (4) output board graphic data, it comprises described fluctuating quantity.
