Application of Chills to Eliminate Casting Defects in Aluminum Cylinder Head
It is difficult to produce aluminum cylinder head by casting because of its complex structure with its uneven wall thickness.In pratical production,some casting defects,such as shrinkage porosity,easily appear.Through application of chills,the shrinkage porosity in aluminum ly linder head was eliminated.The casting's quality and qualified rate of the aluminum cylinder head were improved,and the cost of production was decreased.
