Embodiment 1
[0014] Embodiment 1: 22mm steel plate production method
[0015] Key process steps include:
[0016] 1) Converter steelmaking: Add 125t of molten iron and 30t of scrap steel into the converter for smelting, add 2532kg of silicon-manganese alloy and 108kg of aluminum-iron deoxidation, 300kg of lime, and 200kg of synthetic slag during tapping.
[0017] 2) Refining outside the furnace: add 400kg of lime, 300kg of synthetic slag, 300kg of silicon-manganese alloy, 0.17% of outbound C, 1.26% of Mn, and superheat of molten steel at 12-15°C.
[0018] 3) Continuous casting: the whole process is protected by argon gas, and the section of the billet is 260×2100mm.
[0019] 4) Heating: The temperature out of the furnace is 1163°C, and the time in the furnace is 251 minutes.
[0020] 5) Rolling: Stage I rolling temperature is 1106°C, intermediate billet is 80mm, stage II rolling temperature is 930°C, final rolling temperature is 836°C, and reddening temperature is 560°C.

Embodiment 2
[0023] Embodiment 2: 40mm steel plate production method
[0024] Key process steps:
[0025] 1) Converter steelmaking: Add 125t of molten iron and 30t of scrap steel into the converter for smelting, add 2709kg of silicon-manganese alloy and 98kg of aluminum-iron deoxidation, 300kg of lime, and 200kg of synthetic slag during the tapping process of the converter.
[0026] 2) Refining outside the furnace: add 500kg of lime, 380kg of synthetic slag, 326kg of silicon-manganese alloy, 0.20% of outbound C, 1.42% of Mn, and superheat of molten steel at 12-15°C.
[0027] 3) Continuous casting: the whole process is protected by argon gas. The billet section is 260×2100mm.
[0028] 4) Heating: The temperature out of the furnace is 1178°C, and the time in the furnace is 223 minutes.
[0029] 5) Rolling and cooling: The rolling temperature of the first stage is 1100°C, the intermediate billet is 80mm, the rolling start temperature of the second stage is 920°C, and the final rolling temp...
