摘　　要：介绍了首钢采用低碳成分设计和TMCP工艺开发E级船板的关键控制技术和工艺路线。通过低碳、Nb、Ti微合金化的成分设计、控制钢水纯净度、采用合理的两阶段控制轧制及控制冷却工艺,得到钢质纯净、组织细化的E级船板钢。试制结果表明,拉伸性能、Z向性能、冷弯性能、低温冲击韧性等各项力学性能良好,产品质量完全符合GB712—2000国家标准要求,并达到船级社生产认证要求水平。The key technology and process of E Grade hull plates by low-carbon composition design and TMCP process are introduced in this paper. E Grade hull plates with high purity and structure refinement can be produced through the composition design of low-carbon and Nb and Ti-microalloying, the control of molten steel purity and the adoption of two-stage controlled rolling and controlled cooling processes. Results from pilot production show that with good mechanical properties including tensile property,Z-direction property, cold-bending property and low temperature impact property, the plates conform with GB712--2000 standard and meet the certification requirements of nine country classification societies.
