The present disclosure relates to a cooling device for heat treatment that performs heat treatment by cooling individually or as a whole a heated metal object. The cooling device for heat treatment includes: a chamber to which a plurality of objects is charged through one open side thereof; an individual cooling unit configured to be provided in the chamber, to individually cover the object, and to spray a cooling medium onto the object; and a driving unit configured to be provided on the chamber and to move the individual cooling unit in an up and down direction. With this configuration, it is possible to obtain a required cooling capacity by cooling individually or as a whole a heated metal object.

Cooling device for heat treatment

A vacuum heat treatment apparatus capable of charging or withdrawing an object into or from either a heating chamber or a cooling chamber by a transport means. The vacuum heat treatment apparatus includes: A vacuum heat treatment apparatus, including: a plurality of heating chambers charged with an object and subjected to a heat treatment process; a rail disposed between the plurality of heating chambers; a bogie moving while being disposed on the rail; a cooling chamber disposed on the bogie and cooling the object; and a transport means disposed on the bogie and provided to charge or withdraw the object into or from any one of the plurality of heating chambers and the cooling chamber.

Vacuum heat treatment apparatus

A quenching apparatus capable of quickly reversing a flow of cooling gas flowing in a chamber. The quenching apparatus includes: a chamber provided with a gas inlet and a gas outlet and having an object charged therein; a pair of flow generating means disposed on both sides of the chamber and generating a flow of gas in the chamber; and a flow direction reversing means disposed in the chamber and reversing a flow direction of gas to make the gas flow in any one of a first flow direction in which the gas flows from top to bottom of the object and a second flow direction in which the gas flows from the bottom to the top of the object.
