The method of the present invention includes (A) creating a center segregation image of a slab using an etching solution comprising a picric acid (C6H3N3O7), a cupric chloride (CuCl2), sodium laurylbenzenesulfonate (C18H29SO3Na) and the remainder of distilled water; and (B) evaluating the center segregation of a slab by scanning the image and applying the following Formula. The method creates an image of center segregation even for low-carbon steel having carbon (C) in an amount of 0.04 wt % or less as well as ultra low-sulfur steel having sulfur (S) in an amount of 50 ppm or less."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of evaluating center segregation of continuous cast slab","description":"A method for evaluating center segregation of a continuous cast slab is provided.
