4, Process procedure:
Forging process flow quality control: Raw material steel ingot into
warehouse(test the chemical content) → Cutting→ Forged process→
Post forging heat treatment(N+T)→ UT→ Rough Machining→ UT → QT→
Inspection(UT, mechanical properties, hardness, grain size)→
Grooving→ Stress relieve Tempering → Machining holding postion for
rotor when HST→ HST→ Inspection (dimension)→ Packing and
Marking(steel stamp, mark)→ Storage Shipment
