Features and Benefits

Dense Internal Structure

Controlled large shaft forgings create a uniform grain flow throughout the component. This eliminates internal defects and ensures consistent load-bearing capacity across the entire cross-section.

Superior Mechanical Properties

Our heat treatment process optimizes quality, durability, and wear resistance. You will obtain components capable of withstanding cyclic stacking and impacts without premature failure.

Strong Stacking Capacity

Designed for applications subjected to high torque and pivot loads. Robust cross-sections and high-grade alloy steel ensure your equipment operates safely under maximum design loads.

Customizable Configurations

Pre-machined features such as grooves, steps, and mounting surfaces reduce your auxiliary processing time. We can custom-manufacture to your assembly requirements.

Extended Service Life

Superior materials combined with appropriate heat treatment processes extend service life. This reduces your maintenance frequency and saves on ownership costs.

Dimensional Stability

Stress relief treatments and controlled cooling prevent deformation during use. Your components maintain alignment and mounting resistance throughout their entire service life.

Applications

Power Equipment

Turbine Shafts, generator rotors, and basic drive shafts in hydroelectric and thermal power plants require the dimensional accuracy and fundamental performance offered by our forgings.

Marine Drive Systems

Marine propeller shafts, rudder stock, and crankshafts withstand high cyclic loads in harsh environments. Our corrosion-resistant alloys and robust designs ensure reliable performance.

Mining and Mineral Processing

Ball mill journals, crusher shafts, and crushing process components withstand continuous heavy impact loads. Our high-strength forgings maximize the uptime of equipment in these demanding applications.

Metallurgical Equipment

Rolling process shafts, manufacturing press components, and continuous casting machine parts operate at high temperatures. Our heat-resistant alloys maintain performance under high-temperature cycling.

Wind Power Generation

Main shafts and yaw system components transmit enormous torque while maintaining precise positioning. Our large-diameter forgings provide the strength required for efficient power transmission.

Construction Machinery

Excavator booms, crane hook shafts, and piling machine components demand high quality and durability. Our forgings provide the impact resistance required for these applications.

Testing & Certification

Every forging undergoes rigorous inspection before shipment:

· Dimensional Inspection: CMM verification of all critical dimensions

· Ultrasonic Testing: Internal flaw detection throughout the volume

· Magnetic Particle Testing: Surface crack detection

· Hardness Testing: Verification of heat treatment effectiveness

· Metallographic Analysis: Grain structure examination

· Material Certification: Mill test reports for all raw materials

Our ISO 9001 certified quality system ensures complete documentation and traceability. We provide full material certificates and inspection reports with every shipment.

Installation Guide

Pre-Installation Inspection

Verify all measurements against your drawings some time recently gathering. Check for shipping harm and guarantee defensive coatings stay intact.

Handling Precautions

Use legitimate lifting hardware evaluated for component weight. Bolster shafts at numerous focuses to anticipate twisting amid handling.

Alignment Procedures

Follow manufacturer-specified arrangement resistances. Utilize dial markers to confirm concentricity and straightness amid installation.

Fit Verification

Check bearing fits, keyway clearances, and coupling arrangements. Guarantee all mating surfaces are clean and free of burrs.

Torque Specifications

Apply latch torque agreeing to building determinations. Utilize calibrated devices and take after legitimate fixing arrangements.

Exhibition

We attend many famous international exhibitions such as Shanghai International Maritime Exhibition,Mining World Russia, bauma China, CTT Russia, etc
