What Are The Manufacturing Processes For Ring Forgings?

What are the manufacturing processes for ring forgings?

Core Tip: Ring forgings are a product in the forging industry and a type of forging. It is a circular object formed by applying external force to a metal blank (excluding sheet metal) and shaping it into a suitable compressive force through plastic deformation. This power is typically achieved through the use of a hammer or pressure. The forging process creates a refined particle structure and improves the physical properties of the metal. Ring forgings are ubiquitous in daily life and are an industrial product.

1、 Raw material selection

Normally, the raw material for the production of annular forgings is steel billets or alloy steel billets. When selecting raw materials, it is necessary to consider their material, strength, toughness, wear resistance, and other characteristics and applications to ensure that the produced annular forgings meet the requirements.

2、 Preparatory processing

Before making annular forgings, it is necessary to perform certain preparatory processing on the raw materials, such as removing surface oxide scale and residual impurities, cutting them into suitable sizes, and making them easy to process and forge.

3、 Heating up

Before forging, the raw material needs to be heated to an appropriate temperature, usually exceeding its tempering temperature. The selection of heating temperature should be determined based on factors such as the material and specifications of the raw materials, the shape and size of the annular forgings, and the forging method.

4、 Forging

The heated raw material is fed into a hammer bed or hydraulic forging machine for forging, and it is forged into a ring shape. During the forging process, attention should be paid to factors such as temperature control, hammering force, and frequency. After forging, slow cooling treatment is required to avoid inter granular corrosion and cannibalization.

5、 Post processing

After forging, the annular forgings need to undergo post-processing, including cutting, trimming, drilling, surface treatment, and other processes. Through post-processing, the annular forging can be made to perfectly meet the design requirements.

In summary, the production process of annular forgings includes multiple steps such as raw material selection, preliminary processing, heating, forging, and post-processing. It is necessary to strictly control the process parameters of each step to ensure that the produced annular forgings have high strength, high toughness, and high wear resistance.
