Computer-aided foundry cupola and mold analysis

The ability of making an accurate estimation of the cupola charge involves a considerable time in trial and error calculations to reach an optimum charge selection that fits the available charge material and cost criteria Also an accurate design of the sand mold involves considerable calculations and estimations that rely mainly on the memory of the designer. A computer program has been developed to aid the foundry engineer in selecting the most economic batch from the available cupola charge. The program provides a simple and quick method for calculating the weight of the casting; the dimensions of the cope and drag the areas of gating system; and the volume and diameter of riser. It results in a comprehensive, consistent and time saving method Some case-studies are presented and described.
