Process procedure:
Forging process flow quality control: Raw material steel ingot into warehouse(test the chemical content) → Cutting → Heating(Furnace temperture test) → Heat treatment after forging(Furnace temperture test) Discharge the furnace (blank inspection) → Machining → Inspection(UT,MT,Visal diamention, hardness) → QT→ Inspection(UT, mechanical properties, hardness, grain size) → Finish machining→ Inspection (dimension) → Packing and Marking(steel stamp, mark) → Storage Shipment
