摘　　要：采用离心铸造工艺制备了碳钢-高铬铸铁双金属复合管,并对双金属层的显微组织和性能进行了研究分析。论证了复合管有限元模拟结果,即当内外层金属浇注间隔时间至少为9 s时,可形成规则稳定的双金属过渡层,界面达到冶金结合,并测得复合管抗弯强度为1 236 MPa,抗拉强度为223.01 MPa。The clad pipe with low carbon/high chromium cast iron was produced by centrifugal casting, and its microstructure and properties were researched. The conclusion of finite element simulation for clad pipes was demonstrated, namely a steady-regular and metallurgical bonding transition layer can be formed when the interval of casting was at least 9 s. The metallurgy combination layer were obtained on interface, the bending strength of clad pipe is 1236 MPa, and the tensile strength is 223.01 MPa.
