What is the effect of cutting process on forgings?

Under the conditions of quenching and tempering, annealing, and normalizing of the workpiece, the hardness is lower than 45HRC, and the quality of the workpiece including surface finish, residual stress, machining allowance, surface decarburization, and carbon-poor layer removal, etc. are not significantly affected by cutting processing. As for the change in the latent performance of the forging.

Selection of raw materials when forging forgings

The recrystallization temperature of steel is about 460°C, but 800°C is generally used as the dividing line, and the temperature above 800°C is hot forging; between 300 and 800°C, it is called warm forging or semi-hot forging, and forging is based on the blank during processing. The temperature can be divided into cold forging and hot forging.

About the low-frequency inspection of raw materials for forgings

Low-magnification inspection of forging raw materials. The acid leaching test is a test method to show the low structure of steel materials. In the low-magnification inspection of steel, acid leaching is one of the commonly used methods, mainly because the acid leaching test equipment is simple, easy to operate, and can clearly show various defect structures in steel materials, such as cracks, inclusions, etc. , porosity, segregation and porosity, etc., especially for forgings.

About hardening of forgings

When the forgings are quenched, iron chains are used to hoist the forgings horizontally into the water, resulting in a large amount of steam generated after the lower surface enters the water cannot be discharged in time, forming a steam film, resulting in slow cooling of the lower surface of the forgings, affecting its performance. Moreover, more steam accumulates, causing the forging to vibrate, and there are great hidden dangers.
