REMOVABLE UPPER PORTIONS OF LADLES, LADLES INCLUDING THE SAME, AND RELATED SYSTEMS AND METHODS FOR USE IN MOLTEN METAL PROCESSING

摘要

This disclosure includes removable upper portions of ladles (e.g., ladle extensions), ladles including the same, and related methods for use in molten metal processing. Some removable upper portions of ladles include an open bottom end, a top end, and a sidewall extending between the bottom end and the top end, wherein the bottom end of the upper portion is configured to be removably coupled to an open top end of a lower portion of a ladle, the lower portion further including a closed bottom end and a sidewall extending between the top end and the bottom end, such that, when molten metal is disposed within the lower portion, the upper portion increases the freeboard of the ladle.
