摘要:
The present invention provides a feeder of molten metal for moulds of continuous casting machines comprising a cylindrical body (1) within which a main outflow duct (5) of the molten metal coming from the tundish is formed to which the cylindrical body (1) is connected by means of a frustoconical joint (2), formed integrally with the cylindrical body (1) at the upper end thereof, characterized in that the free end (3) of the cylindrical body (1) is of substantially frustopyramid shape and has a plurality of outlets (7, 8, 9, 10, 11) communicating with the main outflow duct (5).

The invention relates to a method for continuously casting thin metal products, the method comprising the operations of pre-heating a pair of refractory plates (7) for the lateral containment of a bath of molten metal constituted of a pair of counter-rotating rolls (1, 2), and of abutting said pair of plates (7) towards each lateral surface of the ends of said pair of rolls (1, 2), characterised in that is comprises the operations of applying a controlled elastic or elastic/plastic deformation to said pair of plates (7) at the contacting arc between the surface of the plates (7) and the peripheral portion of the ends of said rolls (1, 2), and controlling said elastic and/or elastic-plastic deformation of said pair of plates (7) during the whole casting process, so as to minimize the surface wear of the plates (7) and of the ends of the rolls (1, 2), and to guarantee the maintainment of a predetermined distance between said rolls (1, 2) and said plates (7) lower than a predetermined value, and to minimize the occurrence of leaks of molten metal between said plates (7) and said end parts of said rolls (1, 2).
摘要:
The rolls (1, 2) for a strip continuous casting machine, formed by an outer cylindrical surface and by two flat bases perpendicular to the rotation axis of said rolls, are characterized by the fact that on each of said bases, in correspondence to the edge between them and the cylindrical surface, an annular reinforcing element is placed. Said element is made up by at least one flange (5, 6) realized in a material resistant to the wear caused by mutual contact between the surface of said rolls and the confinement plates.

摘要:
The invention relates to a lateral face (1) of an installation used for the continuous casting of metal bands (5) between two contra-rotating rolls (2, 2') with horizontal axes which are cooled internally. The surfaces of the aforementioned rolls define a casting space which is sealed laterally by means of two lateral faces (1) which are made from a refractory material. The invention is of the type comprising: a support plate (6) on the front face which comprises an opening (7), a hard insert (9) which is disposed on the periphery of the opening (7) and a packing (11) which fills the rest of said opening (7). The invention is characterised in that at least part of the height of the front face (12) of said packing (11), which is turned towards the casting space, is set back by a maximum distance (d) in relation to the front face (13) of the insert.
