- 摘要:
- 论述了一种采用消失模制壳负压浇注的新型铸造工艺,即通过入窑焙烧的方式将泡沫模从型壳中彻底去除,将壳型在砂箱中添加干砂加盖塑料薄膜,然后在负压下浇铸的一种新工艺。以索头铸钢件为例介绍其工艺过程。A new casting process is described.In this process shell mold is made from lost foam,the foam is completely removed by baking in a kiln.The shell mold then is placed in a box and supported by loss dry sand covered with plastic film.Liquid metal is poured into shell mold cavity under negative pressure.Detailed process is explained by cast steel rope clips with this method.
