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 controlled thermal coefficient product manufacturing system and method is disclosed. The disclosed product relates to the manufacture of metallic material product (MMP) having a thermal expansion coefficient (TEC) in a predetermined range. The disclosed system and method provides for a first material deformation (FMD) of the MMP that comprises at least some of a first material phase (FMP) wherein the FMP comprises martensite randomly oriented and a first thermal expansion coefficient (FTC). In response to the FMD at least some of the FMP is oriented in at least one predetermined orientation. Subsequent to deformation, the MMP comprises a second thermal expansion coefficient (STC) that is within a predetermined range and wherein the thermal expansion of the MMP is in at least one predetermined direction. The MMP may be comprised of a second material phase (SMP) that may or may not transform to the FMP in response to the FMD.

A modular industrial energy transfer system includes a shell and at least one energy transfer unit coupled to the shell. The shell includes a plurality of sidewalls, a ceiling member coupled thereto, and a plurality of mounting structures disposed along the shell. The plurality of sidewalls and the ceiling member cooperate to define an interior volume to accommodate a work product. The at least one energy transfer unit is coupled to the shell via at least one of the plurality of mounting structures and is partially disposed through the shell to generate an airflow pattern through the interior volume of the shell.

Provided is a high pressure heat treatment apparatus including: an internal chamber accommodating an object to be heat-treated; an external chamber including a housing and a partition plate partitioning the housing into a high-temperature zone accommodating the internal chamber and a low-temperature zone having a lower temperature than the high-temperature zone, the partition plate including a discharge hole for allowing the high-temperature zone and the low-temperature zone to communicate with each other; a gas supply module configured to supply a process gas for the heat treatment to the internal chamber at a first pressure higher than that of the atmosphere, and supply a protective gas to the high-temperature zone and the low-temperature zone at a second pressure set in relation to the first pressure; and a discharge module configured to open the discharge hole to discharge the protective gas in the high-temperature zone to the low-temperature zone.

A vacuum pressure furnace and/or a cooling plate for a vacuum pressure furnace is described, having a cooling channel or tube that selectively circulates a liquid coolant at a reduced temperature. The cooling channel “snakes” back and forth through a target plate assembly to conduct heat from the target plate assembly and back to the coolant. The target plate assembly includes a plurality of clamp members that are screwed over portions of the cooling channel and to a bottom of a plate member of the assembly, enclosing portions of the cooling channel. Thermal sheets or foil are wrapped around the cooling channel, thereby bridging any gaps between the components that may occur during temperature changes due to thermal expansion/contraction.

A method for forming large titanium parts includes forming bends into a titanium plate for form a bent part. The bent part is then roll-formed to form contours into the bent part. The surfaces of the contoured part are rough-machined, and the part is then secured to a bladed form fixture. The bladed form fixture comprises a plurality of header boards that secure the part to the fixture. The fixture part is placed in a thermal vacuum furnace and a stress-relieving operation is performed. The part is removed from the fixture and final machining takes place.
