Method of Cooling Hot-Rolled Wire Rods. This method cools a rod as it moves from a hot rolling mill. The rod is formed into rings and arranged as a densely packed coil, with the ring centers slightly offset. As the coil travels through an enclosed space, a gaseous heat-transfer medium is adjusted to maintain a substantially uniform temperature across the coil’s external surface and limit temperature differences within its cross-section. The method also vertically drops the rings at least once to help release heat from the coil’s core regions along its edges.

Apparatus for Cooling Hot-Rolled Wire Rods. This apparatus uses a laying reel to form the rod into successive rings and a conveyor to arrange them into a densely packed coil with offset ring centers. A step in the conveyor loosens the coil as it passes over, while an enclosure and stirring devices help maintain progressively decreasing temperatures along the direction of travel. Coolant nozzles at the step direct coolant onto the backs of the vertically dropping rings.

Career Highlights

Nashimoto’s listed patents address both the cooling process and the equipment used to carry it out. Together, they describe ways to manage heat transfer through a moving coil while helping cool its inner regions.
