Production Procedures:
Forging process flow quality control: Raw material steel ingot into warehouse(test the chemical content) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature 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
Advantage:
Excellent mechanical properties,
High-precision dimensional tolerance,
Control the production procedure strictly,
Advanced manufacture equipment and inspection devices,
Excellent technical personality,
Produce different dimension based on customer’ s requirements,
Pay attention on the package protection,
Quality full service.
Application Industries:
Metallurgical equipment, mining equipment, offshore vessels, lifting equipment, construction machinery, power generation, etc.
