摘要
进行了L415MB级油气输送用直缝埋弧焊管中厚钢板的工业试验研究。结果表明，降低C含量，保持与普通16Mn相近的Mn含量，采用Nb、V、Ti微合金化技术结合适当的控轧控冷工艺，按照目前企业的生产装备水平．可以生产符合国标GB9711．2-1999、厚度为10～20mm的L415级管线钢中厚板。
Trial-production of L415MB pipeline plate has been carried out. The results show that decreasing carbon content, keeping Mn content similar to that of plain 16Mn and adopting micro-alloying technology of Nb, V and Ti, and through the TMCP in the metallurgical installments of Shougang Group Corporation, L415MB pipeline steel plates with thickness in the range of 10～20 mm which meet the requirements of the China＇s national standard GB9711.2- 1999 can be successfully produced.
