复杂薄壁叶轮熔模铸造工艺的探讨

Analysis of Investment Casting Process for Complex Thin-walled Impeller

采用精密铸造生产了1.4462双相不锈钢薄壁叶轮,叶轮最薄处仅有1.5 mm。通过对模具设计、射蜡、浇注系统设计、制壳、熔炼等关键工序进行优化和质量控制,成功生产出了薄壁叶轮,所生产叶轮满足技术要求。

The thin-walled impeller of 1.4462 duplex stainless steel was produced.The key procedures were designed strictly to control product quality,such as mold design,injection wax,gating system design,shell making,melting and other key processes.The practical production shows that the quality can meet the customer requirement.
