Abstract
Furnaces esp. for Al and its alloys comprising a crucible and an enclosure surrounding it and maintaining esp. electrical heating means, has means for minimising molten metal splashing the heating elements and the base of the enclosure. There are 2 woven asbestos joints, one disposed in the annular space between the enclosure walls and the crucible and the other on the upper edge of the crucible with a centering piece engaging it. An alarm means in the base of the enclosure acts when molten metal is splashed there and may act to cut off the heating means.
