<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a hot steel sheet and a hot steel plate, in which a plate waveform just after completion of rolling of the hot steel sheet and the hot steel plate is precisely measured and the plate wave form is freely made with a rolling mill based on the result. <P>SOLUTION: In a measuring method for measuring the plate waveform after the completion of rolling of the hot steel sheet and the hot steel plate, positions in the sheet passing direction and the sheet width direction and displacement in the height direction are measured on the outlet side of the rolling mill as geometric values, and then, a profile, steepness and elongation strain difference are determined as the featured value of a shape. Further in the method, residual strain which is immanent in the steel plate when measuring is performed in addition to the measured featured value of a shape and it is superimposed on the measured featured value of the shape as the true featured value of the shape imparted from the rolling mill. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
