Abstract： Systematic change of riser size together with variation of thickness and length of A201 aluminum alloy plate castings were studied to investigate the correlation between riser system and porosity content. The molds with end chill for plate castings were made of 100% chromite sand by CO2 process. If soundness throughout the whole plate casting has to be guaranteed，the riser diameter should be proper design to the dimension of the plate. The Porosity content of A201 aluminum alloy plate casting is governed by riser diameter，thickness，and length of the plate. |
