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.
