Study on Porosity Defect of ZG0Cr13Ni4Mo Guide Vane Casting
The forming cause of porosity defect nearby hot spot of ZG0Cr13Ni4Mo guide vane casting was analyzed.The results show that the porosity is not dispersed shrinkage,but gas-hole caused by N2 and CO.Then responding measures availably solving gas-hole defect of the casting are put forward by practical production.
