description | The invention discloses a method for rapidly determining the cooling speed difference of a steel plate, which comprises the following steps: S1, carrying out hot rolling on a steel plate blank, the thickness of the steel plate blank being more than 12mm, preferably more than 15mm; s2, the hot-rolled steel plate blank is cooled, and cooling comprises laminar cooling; s3, real-time flatness detection is conducted on the cooled steel plate blank, so that a flatness detection result of the cooled steel plate blank is obtained, and the flatness detection result comprises the plate shape of the cooled steel plate blank; and S4, determining the difference between the cooling speeds of the upper surface and the lower surface of the steel plate blank according to the straightness detection result after cooling. The method solves the problem that in the prior art, judgment can only be carried out after sampling and structure performance analysis, real-time performance is achieved, and the cooling speed difference of th |
