Device for continuously casting metals, especially steel
An apparatus for the continuous casting of metals, especially of steel, is equipped with a base frame ( 2 ) carrying a continuous casting mold ( 1 ) and an oscillating device ( 3 ) disposed on the base frame ( 2 ) and with a foot roller frame ( 4 ) disposed on the foot end ( 1 a ) of the continuous casting mold ( 1 ). In order to obtain better protection for the mold region and components disposed downstream thereof, it is proposed that the continuous casting mold ( 1 ) together with an oscillation frame ( 3 b ) and an oscillating drive ( 3 a ) engaging the oscillating frame ( 3 b ) be arranged in an upwardly and laterally closed housing ( 5 ) and that the foot roller frame ( 4 ) fastened on the continuous casting mold ( 1 ) extends through a laterally shielding lower housing ( 6 ).
1. An apparatus for the continuous casting of metal, comprising:
a base frame;
a continuous casting mold mounted on the base frame;
an oscillating unit disposed on the base frame and interposed between the base frame and the continuous casting mold, said oscillating unit comprising an oscillating frame and an oscillating drive engaged with the oscillating frame;
an upwardly and laterally closed housing surrounding in common said continuous casting mold, said oscillating frame and said oscillating drive;
a foot roller frame fastened on a bottom of the continuous casting mold; and
a lower housing laterally shielding said foot roller frame, said first roller frame extending through said laterally shielding lower housing, said laterally closed housing including a housing cover plate having an opening for an upper part of the continuous casting mold and respective lateral housing walls fastened on the base frame and extending from the cover plate to the base frame, the lower housing being fixed on a bottom plate of the base frame and forming a labyrinth seal which surrounds a foot of the mold with clearance.
2. The apparatus according to claim 1 wherein a cover, passing through said opening, is seated on a mold insert and/or a water box, whereby the cover oscillates with the continuous casting mold.
3. The apparatus according to claim 1 wherein the base frame together with the housing cover plate and the lateral housing walls form a transportable unit which can be supported on the foundation or a steel frame.
4. The apparatus according to claim 1 wherein the lower housing is configured so as to be bell shaped with stepped segments which are of increasing size downwardly.
5. The apparatus according to claim 1 wherein the oscillating unit is provided with a hydraulic or electrical drive motor which is disposed on a bottom plate of the base frame.
6. The apparatus according to claim 1 wherein the oscillating unit is provided with a hydraulic or electrical drive motor which is located beneath a bottom plate of the base frame and is surrounded by a protective housing.
7. The apparatus according to claim 6 wherein the protective housing is provided with a water cooling for the hydraulic or electrical drive motor.
8. The apparatus according to claim 1 wherein an electromagnetic agitating coil is arranged in a space beneath the housing cover plate and between the lateral housing walls and above the lower housing.
9. The apparatus according to claim 8 wherein the electromagnetic agitating coil is so arranged as to be of adjustable height in said space.
