[0031] The present invention will be described in further detail below in conjunction with specific examples.
[0032] A 100mm thick Q390E grade extra-thick steel plate, the chemical composition weight percentage of the steel in the steel plate is: C: 0.08-0.13%, Mn: 1.20-1.60%, Si: 0.10-0.25%, P: ≤0.015%, S: ≤ 0.005%, Ni: 0.10-0.40%, Nb: 0.010-0.030%, V: 0.020-0.050%, Al: 0.020-0.040%, and the balance is Fe and unavoidable impurities. The weight percentages of the chemical components of C, Nb and V in the steel conform to the following ratio relationship: 0.26%≤C+6Nb+4V≤0.40%.
[0033] A method for manufacturing 100mm thick Q390E grade extra-thick steel plate, the method adopts the following controlled rolling and controlled cooling process:
[0034](1) Continuous casting slab heating process: the heating temperature of the continuous casting slab with a thickness of 260mm is 1220-1260°C, the temperature of the soaking section is 1200-1240°C, and the heating time in the furn...
