| Abstract: | The new production process was practiced to the 16MnR steel plate melted by 30t top blowing converter.The pass ratio of ultrasonic detection for the plate of which the thickness is less than 25mm was improved greatly through some measurements,such as reducing the amount of S and O in steel,decreasing the inclusions quantity and distribution,and adjusting the controlled rolling process. |
