The present invention relates to an arrangement for treatment of articles by hot pressing. The pressing arrangement for treatment of articles by hot pressing comprises a pressure vessel including: a furnace chamber comprising a heat insulated casing and a furnace adapted to hold the articles. A heat exchanger unit is arranged below said furnace chamber and adapted to exchange thermal energy with pressure medium when the pressure medium is passing through said heat exchanger unit. According to the present invention, at least one first and second inlet or aperture, respectively, for passage of alternating warm and cold pressure medium are arranged in the heat insulated casing in proximity to the heat exchanger unit (i.e. at approximately same the height as, above or below the heat exchanger unit). The at least one second inlet (or lower inlet) is below the at least one first inlet (or upper inlet) but at same height as or below the heat exchanger unit.

An autoclave (1) is one in which a heat application target molded material (W) is retained in shape by a retaining jig (4) which has a cavity (15) therein, and is heat-cured with high temperature gas. The autoclave is provided with: a pressure vessel (2) in the interior of which the molded material (W) is arranged; a high temperature gas supplying device (5) which supplies the high temperature gas to the molded material (W) within the pressure vessel (2); and an auxiliary high temperature gas supplying device (7) which supplies the high temperature gas into the interior of the cavity (15).

Disclosed herein is a nanoparticle generator, comprising a body defining an internal space, with an electric insulator inserted into the internal space from a side of the body; a heat-insulating tube, internally inserted into the body, wherein the electric insulator and a local heating unit which is mounted on the electric insulator are internally inserted into the heat-insulating tube along a central axis thereof; a first inlet, provided at a side of the body, for introducing external air into the heat-insulating tube; a second inlet, provided at a side of the body, for introducing external air between the heat-insulating tube and the body; and an outlet, provided at a side of the body, for evacuating the air introduced through the heat-insulating tube into the body.

An autoclave (1) is one in which a heat application target molded material (W) is retained in shape by a retaining jig (4) which has a cavity (15) therein, and is heat-cured with high temperature gas. The autoclave is provided with: a pressure vessel (2) in the interior of which the molded material (W) is arranged; a high temperature gas supplying device (5) which supplies the high temperature gas to the molded material (W) within the pressure vessel (2); and an auxiliary high temperature gas supplying device (7) which supplies the high temperature gas into the interior of the cavity (15).

The disclosure discloses a heating furnace including a housing, a first rack, a chamber, and at least one fan. The first rack is disposed in the housing. The chamber is disposed in the housing and located at a side of the first rack. The chamber includes an inlet, a first sidewall, and a second sidewall. The first sidewall is adjacent to the first rack. The first sidewall has a plurality of vents. The first sidewall and the second sidewall are disposed to face each other. A width is spaced between the first sidewall and the second sidewall, and the width is larger than or equal to 200 mm. The fan is disposed in the housing for generating an airflow to the inlet.

Provided is a hot isostatic pressing device (HIP) (1) that enables prompt cooling in a processing chamber. The HIP device (1) is provided with the following: gas impermeable casings (3, 4); a heating unit (7); a high-pressure container (2); a heat accumulator (43) provided below a processing chamber; and a cooling promotion flow path (44). The casings (3, 4) are disposed so as to form the following: a first circulation flow (41) in which a pressure medium gas passes through an inner flow path (22) and an outer flow path (12) and then returns to the inner flow path (22); and a second circulation flow (42) in which the pressure medium gas which has branched off from the first circulation flow (41) performs heat exchange with an object-of-processing (W) in the processing chamber and then is fed back to the first circulation flow (41). In the cooling promotion flow path (44), the pressure medium gas that is in the second circulation flow (42) and that has performed heat exchange with the object-of-processing (W) is guided to the heat accumulator (43) and cooled by the heat accumulator (43) before the pressure medium gas merges with the first circulation flow (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.

A furnace system including an outer shell which comprises a top flange, an elongated body portion, and a bottom flange, wherein the outer shell is a pressure vessel, with no penetrations in the elongated body portion; a heater assembly which comprises (i) a single-piece annular shaped insulation layer, and (ii) a plurality of heaters embedded in the insulation layer, wherein the heater assembly is disposed within the elongated body portion of the outer shell; and an innermost layer disposed within the annular-shaped insulation layer, wherein the innermost layer is a baffle tube configured to force a natural convective flow, wherein each of the plurality of heaters is individually controllable and the plurality of heaters are configured to heat different zones within the furnace to different temperatures and/or at different rates. The system may be used to heat treat magnet materials, such as those formed of Bi-2212, therein.

A heat treatment apparatus includes a heating unit, a chamber, an exhaust unit, a partition unit and a switching unit. The heating unit supports and heats a substrate on which a film of a processing liquid is formed. The chamber surrounds the substrate supported by the heating unit. The exhaust unit is configured to discharge a gas from an inner space of the chamber through a discharge opening located near the heating unit. The partition unit is configured to partition the inner space of the chamber into a first space where the substrate on the heating unit is exposed and a second space located above the first space. The switching unit is configured to switch between a first state where the gas is discharged by the exhaust unit through the first space and a second state where the gas is discharged by the exhaust unit through the second space.
