摘　　要：在抗拉强度水平(300MPa)相当的情况下,水平连铸灰铁的疲劳极限(210MPa)比砂铸的(133．8MPa)约高57%。由此得出结论,在应力循环载荷条件下,砂铸灰铁型材完全可以被等强度的水平连铸灰铁型材所取代。Abstract The fatigue strength of the horizontal continuous casting shape gray iron was increased 57% higher than that of the sand mould shape gray iron under the equal tensile strength. The sand mould cast shape gray iron is said to be replaced by the horizontal continuous casting shape gray iron of equal strength under the stress cycling-load conditions.
