Abstract

Under the condition of hand-molding with green clay sand

improvements in process for large thick-walled G-AlSi10Mg alloy frame castings was conducted to optimize the gating system.The experiment indicates that using bottom gating system with large orifice discharge in conjunction with installing cold iron and riser-head can realize the proportional solidification and then avoid shrinkage porosity （hole）

so that qualified frame castings is poured and the production rate is improved.
