Description

Ductile iron lost foam casting of generator main shaft Technical Field The utility model relates to the technical field of lost foam casting, in particular to a ductile iron lost foam casting of a main shaft of a generator. Background The main shaft of the generator is a key bearing component of the generator set, and needs to have high strength, high toughness, good wear resistance and fatigue resistance. The traditional main shaft is manufactured by adopting forging steel or common cast iron, but the forging steel has high cost and long processing period, and the mechanical property of the common cast iron is difficult to meet the requirement of a high-power generator. Spheroidal graphite cast iron gradually becomes an important material choice for the main shaft of the generator due to its excellent comprehensive properties.
