The original distortion measure:50-60%,and then re-crystal rim,and then distortion measure:70-80%& re-crystal rime by turns,for the right size.The distortion measure should more than 50% before every re-crystal rime.Suggest distortion measure 80%.
Casting
Casting temperature: Suggest temperature: 1000-1080蚓
Flasks temperature: Suggest temperature: 500-700蚓
Help-solvent: Suggest using borax as help-solvent,for casting by machine don need it.
Set down casting temperature according to the identity of product, lower flasks temperature for layer product; higher flasks temperature for lighter product.
