The invention relates to a strip-casting machine for producing a metal strip. Said strip-casting machine consists of a pair of casting rolls ( ) arranged in side-by-side parallel relation, two small faces ( ) and a machine tool table ( ) that supports the two casting rolls ( ). Said small faces ( ) can be exchanged by means of a small face exchanging device. The aim of the invention is to reduce the change-over time between two castings, to improve positioning of the small faces and to heat them until start of the casting process while improving the accessibility of the casting rolls for an exchange thereof and while further allowing an optimum inerting of the plant. To this end, the small face exchanging device is configured as a support element, especially as a support arm ( ) for one small face ( ). Said support arm ( ) and said small face ( ) can be displaced in one plane from a pressing position downwards and vice versa in an essentially parallel manner and at a distance to the sealing surface of the small face ( ).

Strip-casting machine with two casting rolls

The invention relates to strip casting machines comprised of two parallel casting rollers ( ) whose bearing journals ( ) are supported on a stand ( ). Cooled roll barrels of the casting rollers ( ) and narrow lateral parts ( ) delimit a casting gap ( ). The aim of the invention is to obtain an optimal ratio between the width of the casting machine and the maximally castable strip width, to provide for a simple stand construction both for changing rollers as well as for exchanging narrow lateral parts, and to attain an improved protection against oxidation. To these ends, the invention provides that the cooled roll barrels are constructed as cylindrical casings ( ). The casing ( ) should be supported on a stationary axle, which is fixed on the stand ( ), via the concentric support rings which project inside the casing ( ) on both sides and which are connected to the same.

Strip casting machine comprising two casting rollers

The invention relates to a strip-casting machine ( ) for producing a metal strip. Said strip-casting machine consists of a pair of casting rolls ( ) arranged in side-by-side parallel relation with a casting gap thereinbetween and of lateral sealing elements ( ) that are provided with respective sealing plates ( ) at both sides of the casting rolls ( ) that are pushed or pressed against the casting rolls from the front by means of pushing or pressing means. The respective sealing plate ( ) is pushed or pressed against the two equilateral front faces ( &prime;) of the casting rolls ( ) in such a manner that, in the heated operational state, it facilitates an extremely exact positioning on the front faces of the casting rolls. To this end, the sealing plate ( ) is mounted in such a manner as to allow a three-dimensional displacement of the sealing plate, as if floating.

Strip-casting machine for producing a metal strip

The invention relates to a strip-casting machine ( ) for producing a metal strip. Said strip-casting machine consists of a pair of casting rolls ( ) arranged in side-by-side parallel relation of lateral sealing elements ( ) that are provided with respective sealing plates ( ) at both sides of the casting rolls ( ) and that adjoin the casting rolls. The contact pressure of the sealing plate ( ) against the casting rolls ( ) and/or the frictional conditions between them can be measured. The sealing plates ( ) at the front faces ( ) of the casting rolls ( ) are positioned at a distance of a few tenth of millimeters or so as to closely fit the front faces ( ) in the operational state, with our without contact pressure. The sealing plates are positioned in such a manner that also in the heated operational state the desired positions of the sealing plates relative to the front faces of the casting rolls are kept very precise.
