目前抗层状撕裂的厚钢板已成为大型焊接结构能否安全使用的关键材料,例如z向钢就是制造海洋采油平台的最重要材料,因为它处在多向接头部位,如果产生层状撕裂,就会导致整个结构的破坏.美国钢铁生产者(Iron & steelmaker)杂志,1982年第4期发表了题为“在炼钢过程中稀土和硫之间的反应及其对钢板厚度方向塑性的影响”的文章,论述了层状撕裂的特性、产生的条件、评价方法及在炼钢过程中防止产生层状撕裂的一些理论和实际问题,对抗层状撕裂钢的研制和生产有直接的参考价值,现摘要介绍如下:
At present, the anti-delamination thick steel plate has become a key material for the safe use of large-scale welded structures. For example, z-direction steels are the most important materials for the offshore oil production platform because they are located at the multi-way joint. Crack, it will lead to the destruction of the entire structure.United States Iron and Steelmaker (Iron & steelmaker magazine, No. 4, 1982, entitled “In the steelmaking process the reaction between rare earth and sulfur and its thickness direction Plasticity, ”the paper discusses the characteristics of layered tearing, the resulting conditions, evaluation methods and prevention of lamellar tearing in the steelmaking process some of the theoretical and practical problems, the development of laminated tear steel And production has a direct reference value, the summary is as follows:
