<p>A remelting process for producing an alloyed ingot having a substantially homogeneous distribution of components which tend to form band macrosegregations, comprises the steps of: providing at least one consumable ingot (10, 12) above a mould (24) the ingot (10, 12) having a composition of the ingot (26) to be produced in the mould (24), the composition having at least two components characterized by their substantially different specific gravities and substantially different melting point; heating a portion of the ingot (10, 12) to a temperature between the solidus and liquidus temperatures of the alloyed composition for forming partially solidified droplets which fall to a mushy body (27) of droplets on the ingot (26) in the mould (24); and solidifying the remaining liquid in the mushy body.</p> |
