Zusammenfassung:	The invention relates to an installation for the heat-treatment of parts ( 2 ), which comprises a rotary hearth ( 4 ) that can be rotated in a timed manner and which has an outer and an inner wall ( 4, 5 ) limiting a furnace chamber that is divided up into a heating zone ( 6 ) and at least one treatment zone ( 7 to 9 ) by means of vertically movable doors ( 5 a- 5 e), the outer wall ( 4 ) in the heating zone ( 6 ) being provided with a closable opening ( 11 ) for charging or discharging the furnace. The installation further comprises a transport device for transporting the parts into or out of the rotary hearth furnace and a quenching device ( 19 ). According to the invention, a second closable opening ( 16 ) is disposed in the outer wall ( 2 ) of the rotary hearth furnace ( 1 ) in the last treatment zone. A sluice ( 17 ) is disposed adjacent to said second opening ( 16 ). The quenching device ( 19 ) is designed as a quenching bath and connected to the rotary hearth furnace by means of the sluice ( 17 ).
