50Mn Large Diameter Forged Steel Flanges Engineering Slewing Bearing Flange
50Mn Large Diameter Forged Steel Flanges Engineering Slewing Bearing Flange
Simple Description:
Slewing bearing flange to be machine processed into slewing bearing,widely used for industrial machinery,engineering machinery,solar power generation equipment,wind power generation equipment,mining equipment,cement machinery.
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
