Embodiment Construction
[0025] Specific embodiments of the present invention will be described in detail below. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0026] As mentioned above, the present invention provides a kind of atmospheric corrosion-resistant molten steel, based on the total weight of molten steel, molten steel contains: 0.01%-0.09% of C, 0.15%-0.35% of Si, 0.30%-0.60% of Mn, 0.30%-0.40% Cu, 0.20%-0.30% Ni, 3.5%-5.0% Cr, 0.13%-0.15% V, 0.004%-0.008% N, no more than 0.030% P and no Greater than 0.020% S. The central quality of the slab (also called continuous casting slab) obtained by continuous casting of molten steel with the aforementioned composition is improved, and the center of the cross section of the continuous casting slab (after acid etching) basically has no central cracks and holes.
[0027] According to the present invention, prefer...
