Defects and Countermeasures of large forgings: Uneven microstructure and properties

Large forgings, due to their large size, many processes, long cycle, non-uniformity in the process, and many unstable factors, often cause serious non-uniformity in the microstructure, so that they cannot pass the mechanical property test, metallographic inspection and non-destructive flaw detect...

Defects and Countermeasures of large forgings: Forging cracks

In large forging, when the quality of raw materials is poor or forging process is not at the right time, forging cracks are often easy to occur. The following introduces several cases of forging crack caused by poor material. (1) Forging cracks caused by ingot defects Most of the ingot defects m... Read More

The forging process of ring forgings

Ring forgings are widely used in industry at present. The forging process of ring forgings is also composed of four parts. The following is mainly to tell you about some ring forging process, I hope you can learn. The forging process of ring forgings mainly consists of the following steps: Pier ... Read More

The basic process of forging

The forging process of forgings is generally as follows: ingots preparation or blank blanking - ingots (blank) inspection - heating - forging - cooling - intermediate inspection - heat treatment - cleaning - final inspection after forging. 1. the ingot is mainly used for the production of medium ...

The influence of various metals on the properties and malleability of steel

Metals are thermoplastic and can be pressed when heated (different metals require different temperatures). This is called malleability. Malleability the ability of a metal material to change shape without cracking during pressure working. It includes the ability to perform hammer forging, rolling... Read More

The difference between casting and forging

Even the precision casting has casting defects, such as shrinkage cavity, trachoma, fractal surface, pouring hole; Forgings on the other hand. You can also drop the product on the floor, and listen to the sound of the crash, usually the sound of the casting muffled, the forging sound more fragile... Read More

How to choose heavy forgings?

Ring forgings is to roll the forgings into a circle, can basically control the dimensional tolerance of the product, reduce the amount of machining. However, when choosing ring forgings, we should be careful not to choose defective ring forgings. If choosing defective ring forgings will seriously... Read More

Forging quality classification

The review of forging quality problems is a very complicated and extensive work, which can be described according to the cause of defects, the responsibility of defects, and the location of defects, so it is necessary to classify them. (1) According to the process or production process of produci... Read More

The influence of die heat meter treatment technology on the economy of forgings

Heat treatment is one of the indispensable important processes in forging die manufacturing process, which plays a decisive role in die life.
