A shuttle kiln (100) according to certain aspects includes at least one flue channel (124) and multiple flue risers (122) in fluid communication with the flue channel (124), and at least one shuttle (104) defining multiple exhaust shafts (140) arranged above the multiple flue risers (122), wherein an aggregate volume of a first exhaust shaft/riser pair (140-1, 122-1) differs from an aggregate volume of a second exhaust shaft/riser pair (140-2, 122-2). Such configuration at least partially compensates for different backpressures that would otherwise be experienced by flue gas exiting a shuttle kiln cavity (138) through different exhaust shafts (140), thereby improving uniformity of flue gas flow and reducing temperature variability within a kiln cavity (138).

The present invention relates to an oven comprising: —a first chamber and a second chambers, which are separated by separation means—conveyor means for guiding products from the inlet through these chambers to the outlet, —temperature control means for controlling the temperature and/or humidity in each chamber individually using a fluid, respectively, and—a passage in the separation means through which the conveyor means are directed from the first chamber to the second chamber.

A vertical-type firing apparatus for a positive electrode material for a secondary battery, for vertically moving and firing the positive electrode material for the secondary battery, comprises: a vertical-type firing furnace including an exhaust part, an air supply part, and a firing space positioned between the exhaust part and the air supply part; and a heater for heating the firing space of the vertical-type firing furnace, wherein the firing space includes a temperature-raising space, a cooling space, and a temperature-maintaining space located between the temperature-raising space and the cooling space, and the temperature of the temperature-maintaining space is higher than the temperature of the temperature-raising space and the temperature of the cooling space.

A shuttle kiln according to certain aspects includes at least one flue channel and multiple flue risers in fluid communication with the flue channel, and at least one shuttle defining multiple exhaust shafts arranged above the multiple flue risers, wherein at least one radiation blockers is arranged above outlet ports of the at least one shuttle. Such a configuration blocks line-of-sight radiant heat transfer between (i) heated surfaces above the shuttle within the kiln housing and (ii) outlet ports of the exhaust shafts, thereby enhancing radiant heat retention and reducing temperature variability within a kiln cavity of the shuttle kiln.

A multi-opening oven assembly for simultaneously heating a plurality of blanks, for example aluminum blanks, before forming the heated blanks in a production line is provided. The oven assembly includes vertically aligned shelves to present a plurality of chambers for heating the blanks. A table including an entry side platform and an exit side platform moves vertically along the oven assembly. A rail system extends along the platforms and the shelves to convey the blanks in and out of the chambers. Once one set of heated blanks is removed from a first chamber, the table moves vertically to a second chamber and is ready to receive the next set of heated blanks. A continuous supply of heated blanks is provided for high throughput. The oven assembly is preferably disposed in a press adjacent a forming station of an existing production line and thus, no additional floor space is required.
