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
