[0019] 1. Smelting process: molten iron pretreatment→converter blowing→LF refining→slab continuous casting→slab cleaning→slab reheating→controlled rolling and cooling→finished product inspection.
[0020] 2. Composition design
[0021] The thickness of the production steel plate is 2.5-16.0mm;
[0022] Composition by weight percentage: [C]: 0.065-0.085%; [Si]: 0.20-0.30%; [Mn]: 0.85-0.950%; [P]: ≤0.020%; [S]: ≤0.004%; [ Cr]: 0.45-0.55%; [Ni]: 0.12-0.25%; [Cu]: 0.25-0.35%; [Nb]: 0.010-0.015%; [Al]: 0.020-0.040%; [Ti]: 0.010- 0.018%; [Ca]: 0.0015-0.0030%; [N]: ≤0.0045%, iron and unavoidable impurities;
[0023] According to the precipitation characteristics of niobium-titanium carbonitride inclusions during the solidification of molten steel (research shows that when the [C] content in molten steel is 0.17%, the [N] content is 0.0040%, [Nb] content is 0.018%, T Ti (C,N) precipitation temperature is less than 1400°C, T Nb The precipitation temperature of (C,N) is less than 11...
