HEAT-TREATMENT SYSTEM AND PROCESS

摘要

Inside a furnace body a number of material-stay spaces are set along a predetermined circular locus of travel of materials to be treated. The furnace body is divided into a heating chamber and a cooling chamber, and some of the stay spaces are located in the former chamber while the others are in the latter. A material is placed into one of the stay spaces located in the heating chamber, and heated therein. Then the material is moved into and stopped at one of the stay spaces located in the cooling chamber, and cooled therein. This process of heating and cooling the material is repeated a predetermined number of times so as to treat the material as desired.
