对Ｗ１６ＭｎＲＱ钢板超声波探伤不合格的试样进行了分析研究，查明了探伤不合格的主要原因是裂纹与ＭｎＳ链状夹杂物。采取改进炉外精炼及轧制工艺等措施，提高了Ｗ１６ＭｎＲＱ钢板的超声波探伤合格率。
W16MnRQ steel ultrasonic flaw detection of unqualified samples were analyzed and studied to identify the main reason for the flaw detection is cracked and MnS chain inclusions. To improve the furnace refining and rolling processes and other measures to improve the W16MnRQ steel ultrasonic testing pass rate.
