Abstract (en)
[origin: WO2020200963A1] The invention relates to a rotary furnace (1) for heat-treating metal workpieces (9), comprising an inner housing (3), which can be rotated about a rotational axis (2), for supplying a furnace gas (16) to heat-treatment areas (6). The inner housing (3) has radially outer heat-treatment areas (6) for the workpieces (9), said areas being rotationally fixed to the inner housing (3) and lying outside of the inner housing (3). The inner housing (3) has nozzle devices (10), through which furnace gas (16) can be conducted out of the interior of the inner housing (3) to the heat-treatment areas (6), and each heat-treatment area (6) is paired with a nozzle device (10) which is rotationally fixed to the inner housing (3). At least one turbomachine (13) is provided through which furnace gas (16) can be conducted past at least one heat source (14) and into the interior of the inner housing (3).
