Abstract
Based on a correlation between the Niyama criterion and radiographic casting soundness developed in Part I of this work, a new set of riser feeding-distance rules is developed for low-alloy steel castings. These rules are designed to produce radiographically sound castings at 2 pct sensitivity. Rules are provided for the riser-zone length, end-zone length, end-effect feeding distance and lateral feeding distance for top risers, and feeding distance for side risers. In addition, the relationships between the end-zone length, riser-zone length, and the various feeding distances are discussed. Multipliers are given to apply these rules with end chills and drag chills, and multipliers are also provided to tailor these rules to different steel alloy compositions, sand mold materials, and pouring superheats. In comparison with previously published rules, the present rules are shown to provide longer feeding distances in most casting situations.
