| titleOfInvention | Production method of high-strength thick steel plate with yield strength of more than or equal to 370MPa |
| abstract | The invention discloses a production method of a high-strength thick steel plate with yield strength of more than or equal to 370MPa, which ensures the uniformity of heating temperature of a plate blank raw material and reduces the interference of temperature on the bad plate shape by controlling a heating process; by controlling the rolling process, the descaling water of the machine body is used once when the rolling is started at the two rolling stages, so that the temperature difference between the upper surface and the lower surface of the rolled piece is formed, the lower surface of the rolled piece is more easily deformed in the subsequent rolling steel biting process, two ends of the formed rolled piece slightly upwarp, the influence on the stability of a roller system caused by the impact of a roller way in the rolling process is avoided, and the transverse small wave bad plate shape of the rolled piece generated by rolling is eliminated; the method realizes the purpose of improving the rolled plate shape of the high-strength thick steel plate by the controlled rolling process design on the basis of not additionally arranging related auxiliary straightening equipment, and the obtained thick steel plate has good plate shape, thereby greatly reducing the enterprise cost and having good economic benefit and social benefit. |
