Example Embodiment
[0015] Example one
[0016] A production process for low-alloy high-strength medium-thick steel plates with an arsenic content of 0-0.05%. The arsenic content is 0.016%. After the medium-thick steel plates are held at 1000-1300℃, they undergo rough rolling and finishing rolling, and the final rolling temperature is At 830℃, the cumulative total deformation is ≥60%. After finishing rolling, it is slowly cooled to 750℃ in air, and then rapidly cooled to 500℃ at 15℃ / s, and then kept warm. The precipitation of carbides in the product is like figure 2 Shown.
Example Embodiment
[0017] Example two
[0018] A production process for low-alloy high-strength medium-thick steel plates with an arsenic content of 0-0.05%. The arsenic content is 0.016%. The medium-thick steel plates are subjected to rough rolling and finishing rolling after 1000 heat preservation, and the final rolling temperature is 830℃. The cumulative total deformation is ≥60%. After finishing rolling, it is slowly cooled to 700℃ in air, and then rapidly cooled to 400℃ at 15℃ / s, and then kept warm.
Example Embodiment
[0019] Example three
[0020] A production process for low-alloy high-strength medium-thick steel plates with an arsenic content of 0-0.05%. The arsenic content is 0.016%. After the medium-thick steel plates are kept at 1100°C, they are subjected to rough rolling and finishing rolling, and the final rolling temperature is 870°C , The cumulative total deformation is ≥60%. After finishing rolling, it is slowly cooled to 730℃ in air, and then rapidly cooled to 450℃ at 20℃ / s, and then kept warm.
