METHOD OF MAKING RIM-STABILIZED STEEL INGOTS

Rim-stabilized steel ingots are produced by teeming a rimming-type steel into an ingot mold until the ingot is about 80-95 percent full, whereupon teeming is interrupted to allow a rimming action in the mold for a period of from 1/2 to 15 minutes. Thereafter, teeming is continued until the mold is f...

Zusammenfassung:Rim-stabilized steel ingots are produced by teeming a rimming-type steel into an ingot mold until the ingot is about 80-95 percent full, whereupon teeming is interrupted to allow a rimming action in the mold for a period of from 1/2 to 15 minutes. Thereafter, teeming is continued until the mold is full. After teeming is commenced following the rimming action, sufficient molten aluminum is added to the mold to produce an SK steel within the rim, all of said aluminum being added prior to completion of the steel teeming.
