Abstract
Disclosed is a rolling method for a board having various longitudinal thicknesses, comprising the following steps: 1) setting a number N of uniform-thickness segments of a sample, thicknesses h1, h2, . . . , hN of the uniform-thickness segments, lengths L1, L2, . . . , LN of the uniform-thickness segments, and lengths T1, T2, . . . , TN−1 of transitional segments between the uniform-thickness segments, the N uniform-thickness segments having N−1 transitional segments therebetween, and both the thickness and length having a unit of mm; 2) selecting a raw material; 3) setting a rolling force, a roll gap and a rolling period of time for each segment; 4) preparing rolling; 5) conducting rolling; 6) optimizing rolling parameters, measuring thicknesses and lengths of the uniform-thickness segments and lengths of the transitional segments after the rolling member is rolled; comparing the measured thicknesses of the uniform-thickness segments with the set thicknesses for the sample, so as to correct the rolling force Pi and roll gap Gi set for each segment in step 3); comparing the measured lengths with the positions marked in step 4), so as to correct the rolling period of time set for ea…
