不銹鋼精密鑄造的注意事項

發布時間:2021-11-19    字號:    
不銹鋼精密鑄造的注意事項如下:
1、我們知道不銹鋼精密鑄造的收縮大于鑄鐵,為了以免鑄件出現縮孔、縮松的缺陷,在鑄造工藝上基本采用冒口、冷鐵、補貼等措施,來實現順序凝固。
2、以免不銹鋼鑄件產生縮孔、縮松、氣孔和裂紋缺陷,要使壁厚均勻、以免尖角和直角結構、在鑄型用型砂中加鋸末,在芯中加焦炭,采用空心型芯和油砂芯來完善砂型或者型芯的退讓性和透氣性。
3、由于鋼液的流動性很差,以免鑄鋼件產生冷隔和澆不足,鑄鋼件的壁厚不能小于8毫米,采用干鑄型和熱鑄型。增加澆注溫度,一般在1520℃-1600℃之間,由于澆注溫度高,鋼水的過熱度大,保持液態的時間長,流動性可以得到完善。
