Heavy-Duty Carbon Steel 45# Coupling Forgings for Mining Conveyors.Heavy-Duty Carbon Steel 45# Coupling Forgings are robust power-transmission components manufactured for high-torque mining conveyor systems. Utilizing open die forging of 45# medium-carbon steel, these forgings deliver exceptional impact resistance and structural integrity in abrasive, high-vibration environments. Engineered to connect drive shafts and pulleys under continuous heavy loads.
Superior Shock Load Resistance
Optimized grain flow withstands conveyor start-up torque spikes.
Enhanced Wear Resistance
Forged surface hardness tolerates abrasive coal/ore dust.
Minimal Defect Probability
≥3:1 forging ratio eliminates internal voids and inclusions.
High Torque Capacity
Shear strength prevents deformation under overloads.
Corrosion Mitigation
Shot-blasted surface preparation enables effective protective coating.
| Conveyor Zone | Component Function |
|---|---|
| Drive Head | Connecting gearbox output to main shaft |
| Take-Up Units | Joining tension carriage shafts |
| Bend Pulleys | Transferring power at directional changes |
| Brake Systems | Installing fail-safe brake discs |
| Counterweight Frames | Securing load-bearing pivot points |
The steel forgings production flow:
raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
