Abstract:
A furnace roller for transporting of a continuously cast stock of a continuously casting plant through a temperature equalizing and heating furnace, comprising a rotatable arbor supported outside of the furnace and having cooling medium channel means provided in an interior thereof; a plurality of tires supported on the arbor and forming a transporting plane for the transported stock; at least one clamping ring provided between a tire and the arbor and formed of one of metal and alloy having a high thermal conductivity and susceptible to both cold and hot deformation; and at least one steel sleeve provided sidewise of the clamping ring, the steel sleeve undergoing, upon heating, a thermal elongation applying pressure to the at least one clamping ring, plastically deforming same, whereby contact surfaces of the clamping ring completely abut associated surfaces of the tire and the arbor providing for a good heat transmission between components of the furnace roller and a reliable torque transmission between the arbor and the tire.
