Embodiment Construction
[0015] The present invention will be further illustrated below in conjunction with specific embodiments, and it should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0016] In the embodiment of the present invention, the low-carbon, low-silicon and aluminum-killed molten steel is smelted in a 250-ton top-bottom double-blown converter, wherein the smelted steel types in Examples 1 and 2 are both SPHC, and the smelted steel types in Examples 3 and 4 are both DC51D+Z. The bottom blowing gas in the converter smelting process is argon; the production method includes: converter smelting, molten steel treatment at the argon blowing station. The control parameters of molten steel production in the embodiment of the present invention are shown in Table 1 to Table 6.
[0017] Table 1 Parameters of converter smelting metal material in the embodiment of the present ...
