An apparatus for removing the lining of a crucible furnace comprises a tubular support which can be introduced into the furnace substantially in the axial direction of the latter. A power-driven tool, for example a pneumatically operated chisel, is movable along the tubular support in engagement with the lining to be removed. Drive means operable from outside the furnace is provided for moving the tool along the tubular support. A suction means is connected to the tubular support for the purpose of extracting, through the tubular support, dust and lining fragments produced during the operation of removing the lining.

Means for removing the lining of a crucible furnace

A tilting device for tilting crucible furnaces is supported in a stand wherein a yoke mounts the crucible furnace to the stand and is pivotable about a shaft extending transverse to the opening of the crucible furnace. The shaft is supported in movable guide tubes mounted within respective upstanding members of the stand. The movable guide tubes are releasably locked within the upstanding members such that operation of a lifting device causes the crucible and yoke to rotate about the shaft and release of the locking means causes the crucible and yoke to be lifted from the stand with operation of the lifting device and movement of the guide tubes within the upstanding members.
