Moving metal strips can be heat treated with any number or combination of dimensionally variable tempers across widths, lengths, or thicknesses of a metal strip. To provide dimensionally variable heat treatment, an apparatus can include one or more heating units suitable to increase the temperature of a metal strip moving proximate the apparatus to a heat treatment temperature. The apparatus can also include one or more cooling units positioned near the heating units to absorb heat and cool the metal strip to minimize the amount of heat transferred from a first region of the metal strip that is to be treated to a second region of the metal strip that is not to be treated.

Provided is a hot isostatic pressing (HIP) device that improves the heat uniformity of a hot zone during a pressurization process of an object being processed. This HIP device (100) is provided with: an outer casing (4) having an open outer opening part (4H); an inner casing (5) having an open inn opening part (5H); a heat-insulating body (R) disposed between the outer casing (4) and the inner casing (5); a gas flow generation part (30); and a plurality of first gas conduits (12), A hot zone (P) in which a pressurization process is performed is formed inside the inner casing (5). During the pressurization process, a low-temperature pressurization medium gas which has been generated by the gas flow generation part (30) and has passed through the first gas conduits (12) moves upward in an inner flow passage (L1) between the casings, and then flows into the hot zone (P) from the inner opening part (5H), Even when the pressurization medium gas leaks from the vicinity of a bottom all part (20) and flows into the hot zone (P), the heat uniformity of the hot zone (P) is maintained.
