A pressing arrangement for treatment of articles by hot pressing includes a pressure vessel including a furnace chamber and a furnace to hold the articles. A fan circulates a pressure medium within the furnace chamber, and enhances an inner convection loop at a load compartment. The inner convection loop pressure medium has an upward flow through the load compartment, and a downward flow along a peripheral portion of the furnace chamber. A flow generator generates a flow of pressure medium into the load compartment downstream the fan to enhance the inner convection loop. The flow is generated by transporting the pressure medium upwards from a space below a bottom insulating portion and above a bottom end portion, and by injecting the pressure medium into the load compartment downstream the fan to enhance the inner convection loop.

Provided is a resin curing device capable of improving work efficiency when curing a liquid resin. A controller (2) of a resin curing device (1) controls opening degrees of three valves (51 to 53) so that a gas flow passage becomes a circulation passage (40) when an execution condition of an operation of feeding air to a curing furnace (10) is satisfied, and controls the opening degrees of the three valves (51 to 53) so that the gas flow passage becomes a bypass passage (41) when the execution condition is not satisfied (STEPS 30 to 41).

A heating device for an annular component is provided. The heating device is configured to heat the annular component via hot gas flow, and includes a gas flow heater, a draught fan, and an annular cavity for accommodating the annular component. An outer wall of the annular cavity is provided with a gas flow inlet and a gas flow outlet, the gas flow heater heats a gas flow, and the draught fan enables the gas flow to enter into the gas flow inlet, pass through a gas flow passage in the annular cavity, and be discharged via the gas flow outlet.
