Continuous heat treatment system for high-pressure fluid storage container

A continuous heat treatment system for a high-pressure fluid storage container, comprising:

• a heat treatment apparatus including a heat treatment furnace in which a heat treatment space is formed, 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 and which is provided under the second transfer unit to cool the high-pressure fluid storage container located in the cooling space as the lifting part is lowered.
