Focus on the problem of porosity defects in cast steel casting,with a focus on analyzing the dissolution behavior of gas in steel,porosity nucleation,growth mechanism,etc.Combined with a practical case of a certain instrument limited company,the actual impact of production environment and sample preparation process on porosity defects in cast steel will be specifically analyzed.At the same time,further research will be conducted on the application schemes of porosity defect control technologies such as metal liquid treatment and casting temperature and speed control,in order to verify the effectiveness of advanced melting technology and new casting process methods through case analysis,and provide reference for improving the quality of castings in the steel casting industry.
