摘要: 采用真空电磁离心铸造方法研究了1025碳素结构钢铸管在950、1250、1450r/min3种离心转速和0、0.052、0.085和0.115T4种磁感应强度作用下的组织和室温拉伸性能。结果表明:在磁场作用下,铸态组织得到明显细化,室温强度与拉伸塑性得以提高,达到了对热轧态材料要求的标准。Abstract: The effects of magnetic induction (0,0.052,0.085,0.115 T ) and rotation speed (950, 1 250, 1 450 r/min) on microstructure and room temperature tensile prop-erty of the vacuum electromagnetic centrifugal casting 1025 carbon steel tube was studied. The results indicate that the cast structure is refined distinctly with electromagnetic density increment, and the room temperature tensile strength and ductility are improved and reached the standards of hot rolling material.
