A heat treatment system includes heating chambers configured to perform heat treatment on objects to be treated, and a conveyance device configured to load each of the objects to be treated into the heating chambers, unload the object to be treated from the heating chambers, and convey the object to be treated under an oxygen-free atmosphere, wherein the conveyance device includes a cooling device configured to perform cooling treatment on the object to be treated.

A powder sintering device is disclosed. The powder sintering device includes a support unit, an actuator unit located on the support unit, a sintering unit, and a reaction unit. The reaction unit is located inside of the sintering unit and heated by the sintering unit. The reaction unit is fixed to the actuator unit and driven to rotate by the actuator unit.

An oven system includes an oven chamber defined by side walls and a top wall. The oven chamber includes a slot formed in the top wall. A conveyor rail extends longitudinally along the slot at a position outside of the oven chamber. A conveyor hanger is coupled to and movable along the conveyor rail to support a material within the oven chamber. A first support bracket and a second support bracket each extend longitudinally along a length of the top wall of the oven chamber. The second support bracket is spaced from the first support bracket to define the slot that extends longitudinally along the top wall of the oven chamber. A closure mechanism is coupled to the first and second support brackets to inhibit heat from releasing out of the oven chamber.
