Cylinder forging

free forging refers to the deformation of steel ingots into the desired shape and size through basic operations such as hammering, upsetting, stretching, and bending without mold limitations. The free forging process is flexible and suitable for single piece and small batch production, as well as the manufacturing of large and complex forgings. We can customize design and production according to customer drawings, and our product range includes shaft forgings, cake forgings, Ring forgings, cylinder forgings, and module forgings. The heat treatment states include annealing,normalizing, quenching, tempering, solution treatment, etc. According to customer needs, the delivery status can be rough machining or precision machining. We can customize the maximum weight of a single forging to be 350 tons, with a maximum length of 30 meters. The maximum diameter of a ring forging can reach 13 meters, and the maximum diameter of a cake forging can reach 6 meters.

Cylinder forgings/hollowed forgings are widely used in energy, automotive, aerospace, shipbuilding, marine engineering, metallurgy, chemical and other fields, playing an important role as key components.

forged ring /rolled ring sizes: The weight of the large ring is 25 tons, the height is 1.5 meters, the outer diameter is 15 meters, and the width of the ring is 1.2 meters!

The melting method of forged material is EF+LF+VD

Heat treament: annealing, normalizing, Quenching and tempering, solution annealing.

Product advantages: 

1. High quality electric arc furnace refining and vacuum degassing process is used for raw material production, ensuring no defects such as pores, sand holes, cracks, etc. in raw materials, low levels of harmful components such as sulfur and phosphorus, and compliance with national standards for harmful gases such as N, H, O, etc;

2. The forging process is reasonable, with a forging ratio greater than 5. The raw material is repeatedly and fully upsetting and elongating to eliminate defects such as porosity, refine grain size, and increase the density of the structure;

3. After forging, tempering treatment is carried out to eliminate forging stress, refine grain size, make the metal structure uniform, facilitate processing, and lay a foundation for subsequent heat treatment;

We are a leading open die & closed die forgings and castings parts supplier, we produce rough machined, semi-finished, and finished parts and fabricated assemblies for demanding applications.
