Abstract
A rectangular parallelepiped ingot defined by a height H, a width W and a length L, having longitudinal faces extending between two end faces, having a volume between 0.15 m3 and 0.80 m3 and a surface area to volume ratio between 10 m−1 and 18 m−1, made of at least one metal, including at least one notch and a notch tip along the ingot length, wherein the at least one notch is configured such that: MaxD<H/2, MaxD<W/2 and MaxD being the maximum distance between any point of the ingot and the closest surface of the ingot.
Claims14
1-13. (canceled)
14:
- A rectangular parallelepiped ingot defined by a height H, a width W and a length L, and comprising:
- two ends faces;
- longitudinal faces extending between two end faces in a length direction, the ingot having a volume between 0.15 m3 and 0.80 m3 and a surface area to volume ratio between 10 and 18 made of at least one metal;
- and
- at least one notch having a notch tip along a length of the ingot, the at least one notch being configured such that:
- MaxD<H/2,
- MaxD<W/2 and
- MaxD being a maximum distance between any point of the ingot and a closest surface of the ingot.
5 more elements
15:
- The ingot as recited in claim 14 wherein the at least one notch extends from a first face of the ingot to a second face of the ingot being the opposite face of said first face.
16:
- The ingot as recited in claim 14 wherein the two ends faces include a first end face opposite a second end face and the at least one notch extends from the first end face to the second end face.
17:
- The ingot as recited in claim 14 wherein the volume is between 0.15 m3 and 0.40 m3.
18:
- The ingot as recited in claim 14 wherein the at least one notch includes at least two notch faces facing each other, the two notch faces forming an angle of 10° to 90°.
19:

21:
- The ingot as recited in claim 14 wherein the at least one notch has a depth at least a quarter of the ingot width W or height H and a ratio between the ingot width W and the ingot height H is from 0.75 to 1.33.
22:
- The ingot as recited in claim 14 wherein the at least one notch has a depth at least a third of the ingot width W or height H and a ratio between the ingot width W and the ingot height H if from 0.66 to 1.5.
23:
- The ingot as recited in claim 14 wherein the at least one notch has a depth of at least a half of the ingot width W or height H and a ratio between the ingot width W and the ingot height H is from 0.50 to 2.
24:
- The ingot as recited in claim 14 wherein the notch tip is positioned between a quarter and three quarters of the ingot width W or of the ingot height H.
25:
- The ingot as recited in claim 14 wherein the notch tip is positioned at half width of the ingot or half height of the ingot.
26:
- A method for managing a bath level of a molten alloy and preventing dross formation inside a tank wherein the ingot as recited in claim 14 is fully immersed into said bath.
