Hvordan fremragende jernbanehjul er udformet: Flittig procesrejse

Vores jernbanehjul have earned strong trust from customers at home and abroad. Mange købere vælger vores hjul, fordi de er nøjagtige i størrelsen, stabil i ydeevne, holdbar i langvarig brug, and always clean and smooth in appearance. These advantages do not happen by chance. They come from our smart production lines, strict process control, and a complete management system that runs through every step. Så, how are our jernbanehjul actually made? Let’s take a clear and simple look at the entire journey together.

1. Preparing the Material for Railway Wheels

1.1 Raw Material Inspection

Everything starts with high-quality steel. Before we begin any production, we check each steel billet carefully. We look at its size, surface condition, and chemical composition. Only clean and stable material can be used to make strong and safe jernbanehjul.

1.2 Cutting and Sizing

After inspection, the billets are cut into the correct length by automatic sawing machines. The machine controls the size very precisely, so every piece enters the furnace with the right shape and weight.

2. Heating and Forming of Railway Wheels

2.1 Heating in the Ring Furnace

Næste, the steel pieces are moved into a large ring-type furnace. The furnace heats the steel slowly and evenly until it reaches around 1,250°C. This step is important because even heating makes the steel easier to shape and helps the final jernbanehjul stay strong during service.

2.2 Pre-Forming the Wheel Shape

When the steel is hot enough, it goes to the pre-forming station. Her, large presses give the steel its first rough shape. It still does not look like a real wheel yet, but the basic outline begins to appear.

2.3 Final Forming Under High Pressure

The nearly shaped steel is then sent to a high-tonnage press. This press gives the wheel its exact structure—the rim, the web, and the hub. The strong pressure also improves the density of the metal, which is key to making durable jernbanehjul.

3. Strengthening and Shaping

3.1 Upsetting and Center Hole Punching

Efter dannelse, the wheel is strengthened again through upsetting. This makes the internal structure more uniform. Så, a special press punches out the center hole, which will later serve as the machining reference point.

3.2 Hot Measurement and ID Printing

Every hot wheel is checked by a 3D laser system to confirm its shape and size. While the wheel is still hot, a unique ID is printed on it. This helps us trace every step of the production process and maintain full quality control for our jernbanehjul.

4. Heat Treatment for Long Life of Railway Wheels

4.1 Controlled Heating and Quenching

The wheels then enter the heat treatment line. Her, they are heated again and quickly quenched with water. This gives the rim the hardness it needs to resist wear and heavy loads on the track.

4.2 Tempering for Stability

Efter bratkøling, the wheels go through tempering. This step reduces internal stress and ensures the jernbanehjul combine strength with toughness, allowing them to work safely for many years.

5. Præcisionsbearbejdning

5.1 CNC Machining of All Surfaces

Heat-treated wheels are sent to our CNC machining centers. These machines finish the tread, flange, hub, and web with high accuracy. Good machining helps the wheel run smoothly on the track and meet strict size and tolerance requirements.

5.2 Final Geometry Check

Each wheel is measured again to ensure all dimensions match customer and industry standards. This makes sure every wheel leaving our factory is consistent and reliable.

6. Kvalitetsinspektion

6.1 Hardness and Surface Testing

We test the hardness of the wheel tread using a Brinell hardness machine. Stable hardness is important because it affects wear resistance and safety.

6.2 Magnetic Testing for Hidden Flaws

Magnetic particle inspection is used to check for tiny cracks in the tread and web. This step helps ensure that all jernbanehjul are free from internal problems.

6.3 Static Balance Testing

Each wheel is tested for balance. A well-balanced wheel reduces vibration and improves performance during service.

7. Final Steps and Delivery

7.1 Final Marking

After all inspections, the wheel receives its final printed or stamped identification. This creates full traceability for future tracking.

7.2 Packaging and Shipment

Endelig, the finished jernbanehjul are cleaned, protected, and packed according to customer needs. They are then shipped safely to railway operators, rolling stock factories, and maintenance centers worldwide.
