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. |
