Abstract (en)
[origin: WO2020002811A1] The invention relates to a method for producing an ingot (2) consisting of a metal compound containing titanium, said method comprising the following steps: supplying fragments of raw material (3); melting the fragments of raw material (3) to form a liquid metal (4) in at least one basin; maintaining the liquid metal (4) in the molten stage in said at least one basin; pouring the liquid metal (4) from the at least one basin into a crucible (15) by overflow of the at least one basin into said crucible (15); and forming an ingot (2) by cooling the liquid metal (4) in the crucible (15); characterised in that the method comprises the following step: preheating the fragments of raw material (3) before the melting of said fragments of raw material (3), at a preheating temperature higher than or equal to 75% of the liquidus temperature of said fragments of raw material (3), and strictly lower than the liquidus temperature of said fragments of raw material (3).
