Embodiment 1
[0051] Select electrical pure iron, metal chromium sheet, metal nickel plate, 304 stainless steel scrap, pure copper block, pure cobalt sheet, metal vanadium as raw materials, and the stainless steel composition is as follows: C=0.03, Ni=9.0, Cr=19.0, V= 0.12, Cu=0.2, Co=0.1, Mn=1.2, Si=0.8, P≤0.035, S≤0.030, Fe=surplus.
[0052] After weighing the corresponding raw materials according to the composition requirements, arc smelting with argon protection. The temperature of the molten pool is kept at 1720 °C during smelting; the molten steel is sedated for 10 minutes before pouring, and the molten steel is poured at 1600 °C under argon protection.
[0053] The plate is hot rolled by a flat roll mill. The hot rolling plan is to heat the cast slab to 1290°C, hold it for 5 hours, and roll it out of the furnace. The starting temperature of hot rolling is 1190°C and the final rolling temperature is 950°C. The total amount of hot rolling of the sheet is 60%.
[0054] The plate is def...
