ABSTRACT:
The present invention relates to a hoist to be used in combination with an apparatus for filtering molten metal. The hoist of the present invention is used both to position the filtering vessel, and to back-flushing metal through the filter element. The present invention also relates to the method of back-flushing. Back-flushing serves to dislodge particulate and thereby clean the filter element. When the filtering vessel is submerged in a molten metal bath back flushing serves to aid the exchange of the molten metal interior to the filtering vessel with the molten metal exterior to the filtering vessel, and in so doing aids in minimizing the temperature difference between molten metal interior and exterior to the molten metal filtering vessel. Periodic back-flushing significantly extends the life of the molten metal filtering apparatus.
