| Item | Details (Heavy Steel Forgings for Wind Turbine Main Shaft Applications) |
|---|---|
| Materials | 42CrMo4, 34CrNiMo6, 18CrNiMo7-6, and other high-strength alloy steels – selected for outstanding toughness, fatigue resistance, and low-temperature impact performance required in wind turbine applications. |
| Forging Equipment | 5T / 8T / 12T Hydraulic Hammers and Ring Rolling Mills – capable of producing large-diameter main shaft forgings up to 6 meters in length and 12 tons in weight, ensuring superior fiber flow and internal homogeneity. |
| Production Process | Open Die Forging → Heat Treatment (Quenching & Tempering) → Rough or Finish Machining → Final Inspection – ensuring high mechanical strength, dimensional accuracy, and consistent metallurgical properties. |
| Forging Ratio | ≥ 3.5 – providing fine grain structure, improved fatigue life, and superior load-bearing performance during turbine operation under cyclic stresses. |
| Application | Designed for use in wind turbine main shafts for both onshore and offshore installations. Also applicable to other renewable energy systems and heavy-duty rotating shafts requiring high mechanical reliability. |
| Delivery Condition | Quenched and tempered; available as forged, rough-machined, or fully machined shafts. Stress-relieved to prevent distortion and ensure alignment accuracy during assembly and operation. |
| Inspection & Testing Equipment | - Chemical Analysis: Spectrometer - Mechanical Tests: Tensile, Impact, Hardness - NDT: Ultrasonic Testing (UT), Magnetic Particle Testing (MT) - Dimensional Control: Coordinate Measuring Machines (CMM), Precision Micrometers - Metallography: Grain size and inclusion rating verification for microstructural integrity |
| Full-Cycle Service | End-to-end production support covering forging, heat treatment, CNC machining, quality inspection, export documentation, and global delivery. All processes strictly comply with ISO, EN, and ASTM standards to ensure reliability and long service life of the main shaft forgings. |
Raw material confirmation and chemical composition verification → Cutting of ingots or billets to specified sizes → Controlled preheating in a temperature-monitored furnace → Precision open-die forging of the main shaft blank → Immediate post-forging heat treatment to refine grain structure → Cooling and visual inspection of surface and shape → Rough machining for dimensional stability → Intermediate quality inspection including UT, MT, and hardness testing → Quenching and tempering (Q&T) to achieve the desired mechanical properties → Final quality verification with ultrasonic testing, tensile and impact tests, hardness, and metallographic examination → Finish machining to precise tolerances → Final dimensional and surface inspection → Product marking, anti-corrosion coating, and packing → Storage and preparation for shipment.
