1. A method of fabricating a furnace roller assembly comprising:
fabricating a linearly oriented shaft-offset and metal contact surface assembly including a wear element, a cooling element connected to the wear element, the cooling element having an internal coolant passage terminating at opposing cooling element supply and return ends, and a support element connected to the cooling element; forming an offset assembly supply opening and a return coolant opening along a furnace roller shaft; providing an offset assembly supply transition fitting and an offset assembly return transition fitting, each of the offset assembly supply and return transition fittings having a first end and a second end opposing the first end; connecting the first end of the offset assembly supply transition fitting to the offset assembly supply coolant opening, and the first end of the offset assembly return transition fitting to the offset assembly return coolant opening; helically bending the linearly oriented shaft-offset and metal contact surface assembly around an outer surface of the furnace roller shaft and connecting the support element to the outer surface, wherein the support element includes a body having a helical shape, a first edge on one side of the body, a second edge on an opposite side of the body, wherein the first edge is connected to the outer surface of the furnace roller shaft and the second edge is connected to the cooling element such that the support element positions the cooling element radially outward of the furnace roller shaft, and connecting the second end of the offset assembly supply transition fitting to the cooling element supply end, and the second end of the offset assembly return transition fitting to the cooling element return end. |
