摘　　要：介绍了宝钢研制高强度高韧性TMCP(热机械控制轧制)40kg级别系列船板的研究结果。结果表明,以低碳微合金化配合适当的控轧控冷TMCP工艺,试制厚度为68mm的高强度DH40、EH40、FH40船用钢板,钢板强度性能满足ABS、CCS、GL等九大船级社规范对DH40、EH40、FH40的要求,在-40℃、-60℃下,钢板横向、纵向具有大于200J的夏比冲击功。同时焊接实验的结果表明,研制的钢板在焊接热输入量为50kJ的条件下,焊接热影响区和熔合线具有良好的低温冲击韧性,能够满足船体结构用高强度高韧性钢板的要求。A study on high strength and high toughness hull construction plates by TMCP at Baosteel is introduced. The properties of high strength DH40, EH40 and FH40 plates with the thickness of 68 mm produced by TMCP conform to the standards of ABC, CCS and GL. The CVN of Charpy on transverse and longitudinal plate is more than 200 J at - 40℃ and - 60℃. There＇ s high toughness at low temperature at HAZ （ heat affect zone） and fusion line when heat input is 50 kJ/cm. The plates can be used for high strength hull construction.
