Although continuous casting is mainstream, the Ingot Casting Machine or mold casting process has not been phased out. Instead, it plays an irreplaceable role in special metallurgy. For certain high-alloy steels, nickel-based superalloys, titanium alloys, etc., which have wide solidification ranges and high thermal sensitivity, the continuous casting process struggles to control their segregation and internal quality. Ingot casting involves pouring molten steel into individual, heavy iron molds (ingot molds) and letting it cool and solidify slowly. Although inefficient and costly, this method allows better control of the solidification process, producing large ingots with uniform chemical composition and sound structure. These high-quality ingots are the essential raw material for forging massive components like ship shafts, wind turbine rotors, and nuclear reactor pressure vessels.
