HIGH PRESSURE GAS JET IMPINGEMENT HEAT TREATMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a furnace for heat treating a workpiece.;SOLUTION: The furnace for heat treating a workpiece includes: at least one high pressure heating zone including at least one fluid impingement device capable of directing a heated fluid medium at a workpiece within the furnace, wherein the fluid impingement device is less than about 6 inches from the workpiece and/or is capable of directing the heated fluid medium at the workpiece at about 4,000 feet per minute. The furnace also includes: a rotating mechanism for rotating the workpiece; a gripping mechanism for inverting the workpiece; and/or an air recirculation system downstream from the high pressure heating zone. The furnace further includes a process control temperature station and/or a sand reclamation system.;COPYRIGHT: (C)2011,JPO&INPIT
