Reoxidation inclusions that form during mold filling can severely diminish the properties of steel castings and often require costly weld repair. Experiments are performed to measure the volume and distribution of reoxidation inclusions in various casting geometries. The molds are 3D printed and filled with liquid steel using a teapot ladle. The cope surfaces are covered by chill plates to avoid shrinkage cavities and allow for the measurement of all inclusions on the casting surfaces. Flat plates of various inclination angles, blocks with cylindrical cores, and ring castings with dirt traps are investigated. The castings are x-rayed and the inclusion distributions on the surfaces are carefully mapped using image analysis. The experimental results are used to validate a previously developed simulation model that calculates the formation, growth, and buoyant transport of reoxidation inclusions during filling. It is found that the model predicts the measured inclusion distributions well.
