Abstract:
A metallurgical furnace unit having a cylindrical furnace body adapted for rotation and/or tilting movement and provided with at least one ring which is arranged outside the furnace body and functions to enable said movement to take place, wherein each ring is disposed at a distance from the furnace body and connected thereto by a force-transferring supporting member which extends in a longitudinal direction of the furnace unit and which is adapted to prevent the transfer to thermal-expansion movement of the furnace body to the ring and to take-up external loads from the intrinsic weight of the furnace body and the weight of the furnace charge, wherein the supporting member comprises a closed mantle which surrounds the furnace body and which is connected to the furnace body and to the ring respectively by an attachment being so flexible as to permit a limited change in the angle between the mantle and the furnace body that can occur as a result of movements of the furnace body caused by thermal expansion, therewith eliminating said movements in the absence of any significant curvature or other deformation of the mantle.
