影響不銹鋼精密鑄造件加工質(zhì)量的因素
發(fā)布日期：2021-06-17 17:12:59瀏覽量：2250
經(jīng)過實(shí)驗(yàn)發(fā)現(xiàn)，硫酸氧化膜是影響不銹鋼精密鑄造件氧化膜純度和透明度的重要元素。其厚度、氣孔率、純度、封孔質(zhì)量等都會(huì)直接干擾鑄件的鏡面效果，如氧化膜中含有雜質(zhì)較多時(shí)，其純度就會(huì)降低，筒體透明度就會(huì)下降。
因此，要保證不銹鋼精密鑄造件的鏡面處理效果，就必須降低氧化膜中的雜質(zhì)含量。因此，必須合理控制薄膜的厚度、孔隙率、純度、封口質(zhì)量，盡量不影響加工。
氧化膜中的雜質(zhì)主要來自不銹鋼精密鑄造件本身，部分來自氧化浴。因此，適當(dāng)降低鑄件中合金元素的含量，可以盡可能地降低雜質(zhì)含量。同時(shí)，減少槽液中的雜質(zhì)離子，保持槽液新鮮也可以提高氧化膜的純度。
可見，不銹鋼精密鑄造件 的鏡面處理工藝也難以順利完成。要想達(dá)到良好的效果，就要去除各種影響因素，使工藝發(fā)揮良好的作用，這樣整個(gè)不銹鋼精密鑄造件 的質(zhì)量也會(huì)相應(yīng)提高。
