Description

The Free Forging Heavy Duty Shaft Forgings For Offshore Wind Power Mining Equipment is a precision-engineered forged component designed for high-load rotary systems in offshore oil and gas exploration. It functions as a key element in top drives, rotary tables, and drilling heads, transferring torque and axial load in critical downhole operations.

Forged from high-strength alloy steels such as 42CrMo4, this spindle offers exceptional fatigue resistance, torsional strength, and dimensional stability under extreme pressures, vibration, and corrosive environments. The free forging process ensures a directional grain structure optimized for high mechanical stress and long-term service life.

Key Features:

  • Open-die forged for high-integrity performance in rotary drilling systems

  • Customized dimensions: splines, threads, shoulders, and flange interfaces

  • Heat treated (Q+T) for maximum strength and toughness

  • 100% Ultrasonic Tested (UT) and Magnetic Particle Inspected (MPI)

  • Optional Inconel cladding, anti-corrosion coating, or stress-relieving available

Applications:

  • Offshore drilling rigs, land-based drilling systems

  • Top drives, kelly drives, rotary tables, and mud motors

  • Ideal for high-torque, high-shock, cyclic loading in deep well drilling

Item Details
Product Name Free Forging Heavy Duty Shaft Forgings For Oil Mining Equipment
Material Grades - High-strength alloy steels: 42CrMo4 - Superior fatigue resistance, torsional strength, and wear resistance for harsh drilling environments
Forging Equipment - Hydraulic hammers: 5T / 8T / 12T - 3600T open-die forging press suitable for long shafts and complex spindle geometries - Supports forging of stepped, splined, and flanged spindle sections
Manufacturing Process Hot Forging → Normalizing / Quenching + Tempering → Ultrasonic Testing → Rough / Semi-Finish Machining → Dimensional & Surface Inspection
Forging Ratio ≥ 3.0 — Optimizes grain flow along spindle axis for enhanced fatigue life and resistance to torsional and bending stresses

The steel forgings production flow:
Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.
