| Item | Details |
|---|---|
| Product Name | Customized large 35# 45# carbon steel forgings transmission shaft |
| Material Grades | - High-strength carbon steel 45# optimized for impact and torque resistance - Custom compositions available for harsh mining environments |
| Forging Equipment | - Hydraulic Presses: 5T, 8T, 12T - Capable of open die forging for medium to large coupling components with axial grain flow |
| Manufacturing Process | Raw Material Inspection → Preheating → Open Die Forging → Heat Treatment → Rough Machining → Non-Destructive Testing → Final Machining (if required) → Dimensional Inspection → Packaging |
| Forging Ratio | ≥ 3.0 — Improves internal grain structure, wear resistance, and load endurance under dynamic conditions |
| Applications | - Couplings for conveyor systems in mining and material handling - Torque transmission joints for bulk transport equipment - Mechanical drive connectors in crushing, screening, and ore extraction systems |
| Delivery Conditions | - Supplied in heat-treated condition (Normalized + Tempered) - Optional: As-forged, stress-relieved, or semi-machined depending on machining process needs |
| Testing & Inspection | - Chemical Analysis (Optical Spectrometry) - Mechanical Testing: Tensile, Hardness - Non-Destructive Testing: Ultrasonic Testing (UT), Magnetic Particle Testing (MT) - Dimensional inspection using precision measurement systems |
The steel forgings production flow:
raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
