Embodiment 1
[0019] The thickness of the nickel-added high-polishing pre-hardened plastic mold steel plate in this embodiment is 80 mm, and its chemical composition and mass percentage are shown in Table 1.
[0020] The production method of nickel-added high-polish pre-hardened plastic mold steel plate in this embodiment includes converter smelting, LF furnace refining, RH vacuum refining, continuous casting slab, controlled rolling and controlled cooling, and high-temperature tempering heat treatment processes. The specific process steps are as follows. Said:
[0021] (1) Converter smelting process: the molten iron entering the converter has a sulfur content of 0.050%;
[0022] (2) LF furnace refining and RH vacuum refining process: after LF furnace refining and RH vacuum refining, qualified molten steel is obtained, with Ni element content of 0.40% and H content of 1.2ppm;
[0023] (3) Continuous casting slab process: the thickness of the continuous casting slab is 220mm, and the specif...
