Abstract
"Shell molds containing additions of ten to fifty percent magnetite, Fe3O4, of various particle sizes were cured by induction heating. For comparison, regular shell molds were made using silica and zircon sand. Low carbon steel was cast into all of the molds.
Castings produced from the regular shell molds exhibited poor surfaces due to mold expansion. Magnetite additions eliminated the expansion defects from the casting surfaces.
Excellent surfaces were obtained on the low carbon steel castings with proper selection of the magnetite particle size and the percent of magnetite added. Improper combinations of size and amount of magnetite resulted in defects associated with the magnetite additions to the mold material"--Abstract, page ii.
