Abstract (en)
[origin: WO0188452A1] The invention relates to a water cooled transport roller for a roller-hearth kiln, comprising a cylindrical base body (1), a thermal insulation (2) on the outer periphery of the base body and a cooling water conduit (3) placed in a central position in the base body. The cooling water can be fed through the conduit (3) at an end of the base body which is rotationally arranged; it then passes through the conduit and flows back through an annular chamber (4) located between the conduit and the base body after a change in direction on the exit side of the conduit. A shaft (5) which is fixed to the base body exhibits a cavity for receiving the water input end of the conduit, a central bore (7) aligned with the rotation axis of the base body, for feeding the cooling water, as well as drain channels for draining the water backflow, which run into a water collecting chamber. The shaft (5) is rotationally connected to a water distributing head (11) for feeding the central bore (7) with cooling water and extracting the water backflow from the collecting chamber.
