厚规格高强度E36船板的开发

Development of the E36 thick high-strength hull plate

介绍了韶钢厚规格E36船板开发情况,采用Nb、Ti、N i微合金化的成分设计,结合洁净钢的冶炼以及合理的轧制冷却工艺,配合正火热处理工艺,结果显示,正火处理后的钢板,从表面至心部组织均匀,晶粒度达到了9.5级,产品力学性能完全符合九国船级社船规要求,表明韶钢成功开发了以正火状态交货的60 mm厚E36-Z35船板.

The thick E36 hull plate was designed and produced at SISG by micro-alloying with Nb,Ti and Ni,elean smelring,proper rolling and cooling, and suitable normalization treatment. The results showed that the steel so produced had a homogeneous microstructure from surface to center, a grain size of 9.5 grade, and mechanical properties fully meeting the specifications from the Ship Society Standard of Nine Countries, thus indicating that SISG has successfully developed the 60 mm thick E36-Z35 hull plate in a normalized delivery condition.
