Abstract
A method and apparatus for quenching an elongated metal workpiece, such as a pipe, bar, tube, or the like, involves, moving the elongated metal workpiece to be quenched longitudinally through at least one rotating spray unit having a plurality of outlets disposed in a substantially even arrangement over an inner surface thereof through which sprays of quenching fluid are directed at the metal workpiece.
Claims18
A quenching spray apparatus for quenching a metal workpiece, comprising at least one rotatable spray unit having a central longitudinal axis and adapted for the positioning of said metal workpiece along said central longitudinal axis, said rotatable spray unit having a multiplicity of fluid outlets disposed over an inner surface thereof and directed to dispose streams of quenching fluid toward said central longitudinal axis.
A method for quenching a metal workpiece comprising positioning said metal workpiece within a surrounding rotating spray unit and subjecting said metal workpiece to a spray of quenchant fluid from a multiplicity of fluid outlets distributed on an inner surface of said rotating spray unit.
A method for quenching an elongated metal workpiece comprising moving said elongated metal workpiece longitudinally through at least one surrounding rotating spray unit along a central longitudinal axis thereof while said elongated metal workpiece is subjected to a spray of quenchant fluid from a multiplicity of fluid outlets distributed on an inner surface of said rotating spray unit.
