Cause Analysis on Perforation and Leakage of Oil Drums Made of REGT1 Low Carbon Steel Sheet

More Information
  • Received Date: December 15, 2016
  • REGT1 low carbon steel sheets with specification of 1 mm×1 000 mm were used to make oil drums in a company, and surface perforation and leakage appeared in several batches of products. The reasons for the perforation and leakage were analyzed by means of macro analysis, metallographic examination, and scanning electron microscope and energy spectrum analysis. The results show that there were several visible large particles in the material at the perforation location. The perforation and leakage of the oil drums was because of the composite inclusions which caused stress concentration and cracks around them during the machining of the oil drums. The cracks continuously propagated and resulted in the leakage failure. According to the analysis results, the steel making and continuous casting technology was adjusted, which greatly reduced the occurrence of similar perforation and leakage failure of the oil drums.
