A continuous heat treatment system for a high-pressure fluid storage container includes a heat treatment apparatus including a first transfer unit which transfers a high-pressure fluid storage container, in which a high-pressure fluid is stored, in a longitudinal direction through the heat treatment space and a heating unit which heats an interior of the heat treatment space to a predetermined heat treatment temperature atmosphere and a cooling apparatus including a second transfer unit which continuously transfers the high-pressure fluid storage container transferred from the first transfer unit in the longitudinal direction and in which a lifting part is formed in at least a partial section to be vertically moved in a state in which the high-pressure fluid storage container is held, a lifting driving unit which vertically moves the lifting part, and a cooling bath in which a cooling space for accommodating a cooling fluid is formed.

A carbon baking furnace has at least one vertical baking shaft with a system and method for positioning green carbon bodies to be baked at the top of the vertical baking path and ringing the green carbon bodies with a sacrificial medium such as packing coke. The disclosure provides a system and method for controlling the delivery and removal of the sacrificial medium used to surround the carbon bodies within the baking paths. A volatile extraction system and method are provided. A system and method for unloading baked carbon bodies is disclosed.
