REGT1低碳薄鋼板加工油桶穿孔滲漏原因分析

REGT1低碳薄鋼板加工油桶穿孔滲漏原因分析Cause Analysis on Perforation and Leakage of Oil Drums Made of REGT1 Low Carbon Steel Sheet

某公司使用規格為1.0 mm×1 000 mm的REGT1低碳薄鋼板加工鍍鋅油桶，不同批次產品均多次出現表面穿孔滲漏問題。采用宏觀分析、金相檢驗、掃描電鏡以及能譜分析等方法對油桶穿孔滲漏原因進行了分析。結果表明：穿孔內部存在肉眼可見的大顆粒夾雜物，油桶穿孔滲漏是由于復合夾雜物部位在油桶加工過程中引起應力集中從而產生裂紋，裂紋擴展并導致穿孔滲漏失效。根據分析結果對煉鋼和連鑄工藝進行針對性的調整后，極大地減少了類似油桶穿孔滲漏失效的發生。

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.
