| High Light | Tempered carbon steel forging ，hydraulic carbon steel forgings ，Shaft Sleeve Forgings | ||
Tempered Carbon Steel Shaft Sleeve Forgings are precision-engineered components designed to protect and align rotating shafts in steel mill drive systems. Manufactured from medium-carbon steel via open-die forging followed by tempering heat treatment, these sleeves provide critical wear resistance and structural support in high-temperature, high-vibration rolling mill environments.
Optimized Surface Hardness
Tempered surface resists wear from shaft micro-motion and abrasive scale.
Thermal Stability
Maintains dimensional integrity under cyclic heating.
Impact Absorption
Absorbs vibration and shock loads from drive train irregularities.
Precision Bore Tolerance
Ensures interference-fit accuracy for shaft mounting.
Directional Grain Strength
Forged grain flow enhances hoop stress resistance.
Rolling Mill Drives:
Gearbox output shaft protection
Pinion stand bearing sleeves
Continuous Casters:
Roll segment drive shaft sleeves
Coil Transport Systems:
Tension reel drive shaft liners
Transfer Tables:
Drive coupling guard sleeves
Run-Out Tables:
Water-cooled roller shaft protectors

| Product Name | Tempered Carbon Steel Shaft Sleeve Forgings for Steel Mill Drive Systems |
| Material Grades | - Medium/high-carbon steels optimized for strength and wear resistance - Tailored compositions for long-life performance in rotating shaft enclosures |
| Forging Equipment | - Hydraulic Presses: 5T, 8T, 12T - Suitable for large-section sleeve forgings with controlled grain orientation |
| Manufacturing Process | Raw Material Inspection → Preheating → Open Die Forging → Heat Treatment (Tempering) → Rough Machining → Non-Destructive Testing → Finish Machining (if required) → Dimensional Inspection → Packaging |
| Forging Ratio | ≥ 3.0 — Improves core strength, surface durability, and dimensional integrity under continuous rolling loads |
| Applications | - Shaft sleeves for main drive units in rolling mills - Protective housings in mill spindles and reduction gear systems - Interfaces for torque transfer in continuous casting drives |
| Delivery Conditions | - Supplied in tempered condition for improved toughness and stability - Optional: Stress-relieved, rough-machined, or final-machined on request |
| Testing & Inspection | - Chemical Composition Analysis (Spectrometry) - Mechanical Testing: Tensile Strength, Hardness - Non-Destructive Testing: UT, MT - Dimensional and surface quality checks using precision metrology |
The steel forgings production flow:
raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
