To provide a method for making an ingot of Ti and Ti alloy or TiAl, which method can surely make the ingot composed of Ti, etc. so as to have an excellent casting surface, and further to provide an ingot making apparatus to be used for the same method.
The apparatus 1 for making the ingot of Ti and Ti alloy or TiAl comprises an induction melting furnace 2 which melts Ti and Ti alloy or TiAl and discharges the molten metal M1 thereof from the tapping nozzle 6 located on the bottom 4 of the furnace, a casting mold 10 which is arranged below the induction melting furnace 2 and can descend relative to the induction melting furnace 2, and a metallic pipe 8 made of Ti, etc., the metallic pipe 8 being hung inside the casting mold 10 from the vicinity of the bottom 4 of the melting furnace 2, wherein the casting mold 10 is supported on the table 12 arranged on the upper end of a hydraulic cylinder 16.
