The invention belongs to the technical field of ocean engineering equipment, and particularly relates to a casting method and application of a duplex stainless steel connecting pin-pin shaft. The casting method of the duplex stainless steel connecting pin-pin shaft comprises the steps of smelting molten steel, pouring the molten steel into a casting mold rotating at a high speed, taking out a casting after cooling, quickly putting the casting into a heat treatment furnace, and quickly cooling after heat treatment. A duplex stainless steel material is selected for smelting molten steel, pouring is carried out under the centrifugal force effect of high-speed rotation, a casting is obtained through pouring, the casting is taken out and then rapidly put into a heat treatment furnace which is heated in advance, and finally the pin shaft casting which is compact in structure and good in mechanical performance is obtained.

    本发明属于海洋工程设备技术领域,具体涉及一种双相不锈钢连接销‑销轴的铸造方法和应用。所述双相不锈钢连接销‑销轴的铸造方法,包括熔炼钢水、浇注到高速旋转的铸型中,冷却后取出铸件,快速放入热处理炉中,热处理后快速冷却。熔炼钢水选用双相不锈钢材料,在高速旋转的离心力作用下进行浇注,浇注得到铸件,取出后快速放入预先升温的热处理炉中,最终得到结构致密,机械性能好的销轴铸件。
