摘要: 针对高强船板EH36在拉伸试验时试样的1/2厚度附近出现的严重分层现象,利用金相检验、扫描电镜观察等手段对试样断口及剖面进行分析研究,明确了分层产生的原因,并提出相应的控制措施。研究结果表明,造成钢板中心分层的直接原因是带状组织和中心的层片状MnS夹杂,而根本原因是连铸过程中C、Mn、S的中心偏析。

Abstract: Serious spitting phenomenon occurred in the center of the plate during tensile test of high strength steel EH36 for ship plate use.Metallographic examination and scanning electron microscope have been taken to observe the fracture and section of specimen.And then the causes of splitting have been identified and corresponding control methods have been proposed.The study results show that the direct reasons for splitting include banded structure and lamellar MnS inclusion in the center of the steel plate,while the fundamental reason is the central segregation of carbon,sulphur and manganese during continuous casting process.
