The invention relates to a strip-casting machine for production of a metal strip, comprising two adjacent case-width casting rollers (22, 24), forming a casting gap (15'), with side seals (25) arranged on the front face thereof. The rotating casting rollers are mounted on a machine mount (32). Between the above and the side seals (25), the metal melt, introduced by means of at least one casting tube (13), or similar, is protected by at least one gaseous medium. At least said casting rollers (22, 24) are surrounded on at least the case width and front face thereof as well as the side seals by a preferably multi-component housing (30, 60, 80). An optimal sealing of the casting rollers as well as the metal strip and the metal strip appearing from between the rollers can thus be achieved in a simple manner.

The invention claimed is: 1. 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. 2. Strip-casting machine according to claim 1, wherein the housing (30) is box-shaped and is located a certain distance away from both the sides and the top of the casting rolls (22, 24 ). 3. Strip-casting machine according to claim 1, wherein a sealing system housing (60), which cooperates with casting rolls (22, 24) and the side seals, is assigned to the bottom of each of the doors (35), which sealing system housing forms a chamber above the molten metal pool between the casting rolls, this chamber being separate from the other chamber in the longitudinal housing. 4. Strip-casting machine according to claim 3, wherein the chamber formed by the sealing system housing (60) is filled with an inert gas, while the other chamber (33) in the housing is filled with another inert gas. 5. Strip-casting machine according to claim 3, wherein the housing forms a frame and is water-cooled.
