大型高铬铸铁叶轮的生产工艺

Technology for Large Blade Wheel of High Chromium Cast Iron

高铬铸铁具有良好的耐磨性,但它是一种脆性材料,通常只用于生产形状简单、体积较小的铸件。本文通过合理设计铸造工艺,利用计算机凝固模拟技术,同时严格控制现场生产过程,成功地生产出了形状复杂、质量较大的高铬铸铁叶轮。

Heavy blade wheel of high chromium cast iron with complex figure has been produced successfully with reasonable designed casting technology, technology of computer simulation of solidification and rigorous production control.
