本发明提供一种连铸坯偏析程度定量化表征方法，能够定量化地表征连铸坯偏析的严重程度。所述方法包括：获取待分析连铸坯的厚度截面的照片；对获取的所述照片进行二值化处理，得到包括偏析点和基体的图像；将所述待分析连铸坯的厚度方向定为指定向坐标，根据得到的包括偏析点和基体的图像，统计所述指定向标上坐标值对应的偏析点占厚度截面照片的总像素点的比例，作为所述指定向坐标上的厚度值对应的偏析比例；根据得到的偏析比例，提取特征量以评判所述待分析连铸坯偏析的严重程度。本发明涉及炼钢连铸技术领域。

The invention provides a quantitative characterization method for continuous casting billet segregation degree, which can quantitatively characterize the severity of continuous casting billet segregation degree. The method includes: obtaining a photo of the thickness section of the continuous casting billet to be analyzed; The obtained photos are binarized to obtain images including segregation point and matrix. The thickness direction of the continuous casting billet to be analyzed is set as the specified direction coordinate, and according to the obtained image including the segregation point and the matrix, the proportion of the segregation point corresponding to the coordinate value on the specified direction index to the total pixel point of the thickness section photo is counted as the segregation proportion corresponding to the thickness value on the specified direction coordinate. According to the segregation ratio obtained, the characteristic quantity is extracted to evaluate the segregation severity of continuous casting billet. The invention relates to the technical field of steelmaking continuous casting.
