This paper briefly describes the characteristics of gas hole defect appearing in the trial production process of a heavy car with six cylinder cast iron cylinder head castings, and analyzes the cause that the blowhole defects appears on the oil shell surface. Then, the writer introduces several main process methods to reduce this kind of pore defects in use: pouring system improvement, sand core of water jacket peritoneal sand the optimization selection, sand core exhaust system optimization, liquid metal purification treatment measures, so that, the production of heavy vehicles with six cylinder cover effectively reduces the porosity defect.
