Abstract
A water-cooled furnace roll has a hollow rotating arbor, having cooling fluid passages formed therein, wherein the arbor is formed from a heat resistant centrifugally cast alloy, and a plurality of annular tires spaced along said arbor and secured to the arbor, wherein the spaces between the tires is adapted to receive refractory material to insulate the arbor.
Claims20
A water-cooled furnace roll comprising:
- a hollow rotating arbor, having cooling fluid passages formed therein, wherein the arbor is formed from a heat resistant centrifugally cast alloy;
- and
- a plurality of annular tires spaced along said arbor and secured to the arbor, wherein the spaces between the tires is adapted to receive refractory material to insulate the arbor.
An arbor for a water cooled roll of a roller hearth furnace, the arbor configured to have a plurality of spaced tires with refractory insulation there between, and including internal passages for cooling fluid, the improvement comprising wherein the arbor is formed from a heat resistant centrifugally cast alloy.
A water-cooled roll for transporting material through a furnace, the roll comprising:
- a hollow rotating arbor, wherein the arbor is formed from a heat resistant centrifugally cast alloy;
- a water supply pipe positioned within said arbor spaced from the inner walls thereof by a plurality of spacers on an outer periphery of said pipe to create an annular space there between;
- a plurality of annular tires spaced along said arbor, each said tire including an annular body having an outer work contacting surface and an inner bore sized to receive said arbor therein;
- and
- a plurality of locking bars attached to said arbor, each said locking bar extending into one said recess of one said tire.
