| description | The invention discloses an evaluation method for edge recarburization of a continuous casting billet based on a metallographic method, and belongs to the technical field of metal detection. The method comprises the following steps: performing analyzing by using a metallographic microscope to obtain pearlite contents X in different areas of a standard sample of the metallographic sample; obtaining the carbon segregation index Y = C < measurement >/C of the sample by using an electronic probe or an in-situ analyzer; using smelting pearlite contents in different analysis areas of each metallographic sample standard sample and a corresponding carbon segregation index P = C < measurement >/C to form a data set, and establishing a relationship characterization formula Y = a * X + b of the pearlite content X and the carbon segregation index Y, a and b being correction coefficients; taking a metallographic sample from an edge area of a continuous casting square billet, obtaining the pearlite content X1 of a carbon se |
