摘　　要：超声波探伤是检验中厚板内部缺陷的主要方法，能够造成探伤不合格的缺陷主要包括裂纹、偏析、夹杂物。结合秦皇岛首秦金属材料有限公司生产情况，分析了中厚板探伤缺陷的机理，发现钢中的氢含量、铸坯质量、生产工艺是影响中厚板探伤质量的主要影响因素。通过有效控制上述因素，可显著提高中厚板的探伤合格率。Ultrasonic testing is a main method to check the internal defects of steel plate. The defects that can cause ultrasonic testing unqualified mainly include crack, segregation and inclusion. This paper combined Qinhuangdao Shouqin Metal Material Co Ltd production situation, analyzes the mechanism of steel plate defect, it is found that the hydrogen content in steel, continuous casting billet quality and production process are main factors affecting the quality of steel plate. Through effective control of the above factors, can significantly improve the uhrasonic qualified rate of testing plate.
