Abstract
PURPOSE:To prevent the quenching water from intruding into the furnace, by equipping the nozzle head having plural nozzle holes slanted by a specified angle for the shaft line and the conical guides more than one having the outer diameter slightly smaller than the inner diameter of the steel pipe at the end part of the pipe which is inserted into the steel pipe to be hardened.
