s2, the tip of the measuring block (5) is always in contact with the surface of the hot rolled coiled sheet (6) in the moving process, the measuring block (5) swings along with the flatness of the surface of the hot rolled coiled sheet (6), the angle sensor (2) records the swinging amplitude of the measuring block (5), and signals are transmitted to a computer system;
s3, analyzing the path data after the computer system receives the data, substituting the angle and the path information at the maximum tolerance value of the measured angle data into a calculation formula for calculation, and obtaining the camber degree and the camber size of the hot-rolled coiled sheet material (6); the calculation formula is as follows:
Δ θ is: measuring the maximum value of the angle tolerance;
Δ x is: the value of the path between the maximum tolerance angles.
