ABSTRACT:
Thermal insulating gaseous blankets, generated by contact of a quench liquid with a hot metal workpiece, are displaced from downwardly directed surfaces by sequentially elevating the workpiece, at points about its periphery, so as to promote migration of the trapped gas across such surfaces. The improved heat transfer that results increases the levels of hardness and strength exhibited by the treated workpiece.
