Discussion on a stainless steel turbine shell blank casting process
According to the material and structural characteristics of a newly developed austenitic tur-bocharger turbine shell,the blank casting process was discussed,the pouring position was determined,and the process of semi-closed gating system,riser shrinkage and cold iron quenching were designed,the filling and solidification process of molten steel was simulated and calculated by AnyCasting software,and the process scheme was determined and the process equipment was designed and manufactured through comprehensive analysis.In view of the casting defects such as shrinkage porosity,cracks,and cold isolation that occur in the verification process of the trial production process,countermeasures were taken to improve them,and finally the castings that meet the quality requirements were produced,which provides a reference for the process development and production of similar blanks.
