| Abstract: | The influence of steelmaking,rolling and ACC process parameters on the microstructure and the result of ultrasonic flaw detection was studied by the analysis on the sample from X80 pipeline steel plate.The results show that the center segregation,cracking,inclusions like MnS and hydrogen in steel plate have negative effect on the result of ultrasonic flaw detection. |
