Document Type and Number:
WIPO Patent Application WO/2014/133255
Kind Code:
A1
Abstract:
According to the present invention, provided is a method for controlling surface quality of a ultra-low carbon steel slab, the method comprising the steps of: measuring the phosphorus (P) content, the sulfur (S) content, and the degree of superheating of molten steel input in a mold at the time of continuous casting for manufacturing the ultra-low carbon steel slab, the width of the mold, and the casting speed of the slab; and calculating the depth of a hook, which is formed when the molten steel solidifies into the slab, from the measured phosphorus (P) content, sulfur (S) content, and degree of superheating of the molten steel, width of the mold, and casting speed of the slab.
