Product Description
Products reference:
Forging steel shafts are use in industry, such as forging equipment; power plant equipment; hydraulic equipment; rolling mill equipment; petroleum machinery, etc.
The production process as "EF + (LF) + (VD) + ESR + forging and annealing (or normalizing) + heat treatment (quenching and tempering) + Machining + packaging + delivery. "
Quality control: chemical analysis, optical spectrum instrument, Mechanical properties for tensile strength, yield stress and elongation. Hardness testing, impact testing, coordinate measuring machine (CMM), metallographic analysis, magnetic flaw detector, Ultrasonic flaw detector.

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
