| Abstract: | The samples of W16MnRQ steel plate rejected by the ultrasonic flaw detection are analysed and the primary factors that cause the occurrence of substandard products by the ultrasonic flaw detection are found to be the existence of cracking as well as chain type inclusions in steel.Improvement in the ratio of qualified W16MnRQ steel plate has been achieved by taking appropriate corrective actions in the secondary steelmaking and rolling processes. |
