Claim:
Strip-casting machine for the production of a metal strip with two adjacent casting rolls with lateral surfaces of a certain width which form a casting gap between them, the end surfaces of the rolls being provided with side seals, the rolls being rotatably supported on a machine stand and driven by at least one motor, where the molten metal is supplied through at least one casting tube to the area between the casting rolls and the side seals, and is protected by at least one gaseous medium, wherein a multi-part housing encloses at least the lateral surfaces and ends of the casting rolls and the side seals, the housing having an opening in the top for the casting tube extending into the area between the casting rolls and having an opening at the bottom for the metal strip emerging underneath from the casting gap between the casting rolls, the housing having at least one removable, approximately horizontal door on top, which, when closed, is directly above the casting rolls, the housing being positioned in a moveable frame stand, wherein an additional, longitudinal housing ( 44 ) is provided underneath the housing ( 30 ), this additional housing forming a chamber ( 45 ), through which the metal strip ( 15 ) is conduct, and wherein the opening ( 30 ″, 70 , 84 ) provided in the bottom of the housing ( 30 , 60 , 80 ) for the emerging metal strip ( 15 ) communicates with the longitudinal housing ( 44 , 65 , 85 ) and connects the chamber of the housing with the chamber of the longitudinal housing directly and separates them in a nearly gas-tight manner by means of a seal, and wherein the seal of the slot-shaped opening ( 30 ″) in the bottom of the housing ( 30 ) consists of nozzles that provide a gas shield.
