Embodiment Construction
[0024] Below in conjunction with specific embodiment 1-8, further illustrate the present invention.
[0025] In the embodiment of the present invention, a 150-ton top-bottom combined blowing converter is used to smelt the grade as MR-2 tinplate electroplated tin plate, and the bottom blowing gas in the converter smelting process is argon. The production method includes: converter smelting, molten steel treatment at an argon blowing station, and continuous casting of molten steel by a continuous casting machine. The control parameters of molten steel production in the embodiment of the present invention are shown in Table 1 to Table 6.
