Abstract

1529664 Spray-producers NIPPON KOKAN KK 26 Jan 1977 3128/77 Heading B2F [Also in Division C7] A metal pipe is quenched internally by relative motion between it and an annular cooling head 2 having peripheral nozzles 4 which discharge jets of liquid or mixed liquid-gaseous coolant inclined at an angle (d) of 30-70‹ to the radial plane of the head in the direction in which the pipe is moving, and at an angle (#) of .30-90‹ to the radii of the head, whereby the coolant flows along the tube bore in a helical path away from the hot region. The coolant leaves the nozzles at >5 m/sec, and is preferably either water or a water-air mixture.
