Abstract
A cooling device comprises a manifold housing having a generally concave inner edge configured and dimensioned to surround a surface area of a work roll in a rolling mill. The manifold housing is of a modular design having multiple constituent sections that are internally configured to simultaneously apply both a liquid coolant and a pressurized gas to the surface area of the work roll.
Claims11
A cooling device for a work roll in a rolling mill, said device comprising:
- a manifold housing having a generally concave inner edge configured and dimensioned to surround a surface area of the work roll;
- first means for applying a liquid coolant to said surface area via first outlets arrayed along the inner edge of said housing;
- and
- second means for simultaneously applying pressurized gas to said surface area via second outlets also arrayed along the inner edge of said housing, wherein
- said first nozzles are located in parallel first planes, and said second nozzles are located in a second plane between and parallel to said first planes, and wherein said first nozzles are alternately arranged in a staggered relationship on opposite sides of said second plane.
A cooling device for a work roll in a rolling mill, said apparatus comprising:
- a manifold housing having a generally concave inner edge configured and dimensioned to surround a surface area of the work roll, said housing comprising exterior first sections sandwiching an interior second section therebetween;
- first means comprising networks of first grooves on interior surfaces of said first sections for applying a liquid coolant to said surface area via first outlets arrayed along the inner edge of said housing;
- and
- second means comprising a network of second grooves on said interior second section for simultaneously applying a pressurized gas to said surface area via second outlets also arrayed along the inner edge of said housing.
A method of cooling a work roll in a rolling mill, said method comprising:
- applying a liquid coolant to a surface area of the work roll;
- and
- simultaneously applying a pressurized gas to the same surface area.
