Abstract
Equipment for the continuous hot dip-coating of a metal strip 9 including an annealing furnace, a tank 2 containing a liquid metal bath 3, a snout connecting the annealing furnace and tank 2, through which the metal strip 9 runs in a protective atmosphere and the lower part of the snout, the sabot 5, is at least partly immersed in the liquid metal bath 3 in order to define with the surface of the bath, and inside this snout, a liquid seal 6, an overflow 7 not connected to the snout, the overflow 7 including at least one tray 8, placed in the vicinity of the strip 9 when entering the liquid metal bath 3 and encompassed by liquid seal 6.
Claims15
Equipment for continuous hot dip-coating of a metal strip, the equipment comprising:
- an annealing furnace;
- a tank containing a liquid metal bath;
- a snout connecting the annealing furnace and the tank, the metal strip running through the snout in a protective atmosphere, a lower part of the snout being at least partly immersed in the liquid metal bath in order to define with a surface of the bath, and an inside of the snout, a liquid seal;
- and
- an overflow independently movable with respect to the snout and including at least one tray placed in a vicinity of the strip when the strip enters the liquid metal bath and is located within the liquid seal, the at least one tray being formed by:
- an internal wall facing one side of the strip, directed toward a surface of the liquid seal, an internal wall upper edge being positioned below the surface of the bath;
- an external wall facing the snout, directed toward the surface of the liquid seal, an external wall upper edge being positioned above the surface of the bath;
- a connector part between the external and internal wall lower edges and also
- a side wall at each shared extremity of the internal and external walls connecting all edges;
- the internal wall upper edge being lower than the external wall upper edge.
Equipment for continuous hot dip-coating of a metal strip, the equipment comprising:
- an annealing furnace;
- a tank containing a liquid metal bath;
- a snout connecting the annealing furnace and the tank, the metal strip running through the snout in a protective atmosphere, a lower part of the snout being at least partly immersed in the liquid metal bath in order to define with a surface of the bath, and an inside of the snout, a liquid seal;
- and
- an overflow independently movable with respect to the snout and composed of one tray continuously surrounding the metal strip formed by an internal wall facing one side of the strip, directed toward the surface of the liquid seal, an internal wall upper edge being positioned below the surface of the bath, an external wall facing the snout directed toward the surface of the liquid seal, an external wall upper edge being positioned above the surface of the bath, a horizontal wall between the external and internal wall lower edges.
