Abstract
A method for manufacturing an ingot made of titanium-based metallic compound, includes providing raw material fragments; melting the raw material fragments into a liquid metal in at least one basin; keeping in the molten state the liquid metal in the at least one basin; pouring the liquid metal from the at least one basin into a crucible by overflow from the at least one basin into the crucible; forming an ingot by cooling of the liquid metal into the crucible; wherein the method further includes preheating the raw material fragments before the melting of the raw material fragments with a preheating temperature higher than or equal to 75% of the liquidus temperature of the raw material fragments, and lower less than the liquidus temperature of the raw material fragments.
