锅炉压力容器用钢板超声波探伤不合的原因分析

Causes Analysis of Non-Conformity in Ultrasonic Flaw Detection of Steel Plate for Boil and Pressure Vessel

本文通过低倍检验、拉伸断口、Z向断口形貌,简要分析锅炉压力容器用钢板探伤不合的主要原因,并对冶炼、轧制等工序环节提出了改进建议。

From macroscopic examination, tensile fracture and through thickness fracture pattern , the article briefly analyses the main factors of nonconformity in ultrasonic flaw detection of steel plate for boiler and pressure vessel, and brings forward the improvement advices for production procedures during melting and wiling.
