Why do large forgings need to be heat treated after forging?

The purpose of heat treatment after forging large forgings is to refine the coarse grains caused during the forging process, eliminate work hardening and residual stress, reduce hardness, improve machinability, prevent the formation of white spots inside the forgings, ensure the desired metal structure and mechanical properties, and prepare for the final heat treatment.

Cooling Methods for Large Forgings

The cooling methods for large forgings mainly include the following: water cooling (including spray cooling), oil cooling, air cooling (natural air cooling and forced air cooling), gap cooling (water-air, water-oil, oil-air), and spray cooling. The commonly used quenching media for large forgings are water, oil, and air.

Practical Tips for Finishing Forgings

With the development of the times, the precision requirements for workpieces and forgings in industrial production are becoming increasingly high. Ordinary rough machining is often unable to meet the personalized needs of different customers. Therefore, most processing plants, during the production of forgings, often go through semi-finishing and finishing steps after initial processing, which greatly increases the precision of the produced workpieces and enhances the overall competitiveness of the enterprise. So, what exactly is finishing? What techniques are involved in the finishing of forgings?

What are the excellent characteristics of forgings?

For metal components, there are generally two methods: casting and forging. Casting is mainly suitable for the production of components that do not have high precision and quality requirements. However, forging is different; forged parts are superior to cast parts because casting does not change the original microstructure and mechanical properties of the metal. The fibrous structure increases the strength and toughness of the metal, making it very suitable for wear-prone components. Additionally, forged parts are more conducive to operations such as welding, deformation, and plasticity, and their performance does not change significantly after these processes. Therefore, forged parts are widely used in modern industry.
