What are the differences between ring forgings and castings
Ring forging is made by forging, and forging is made by impact force. The casting is made by casting. The casting is made by pouring molten steel into a mold or model. Casting is the process of forging, in which the metal is melted into liquid that meets the requirements and poured into the casting mold, and the castings (pieces or blanks) with predetermined shape, size and performance are obtained after cooling, solidification and cleaning treatment.
The castings will have formed shrinkage holes, sand holes, fractal surfaces and pouring holes; Ring forgings have no performance. At the same time, the product can also be dropped to the ground, and then the impact sound can be heard. Generally, the casting makes a dull sound, and the ring forging makes a brittle sound. This is the main difference between ring forgings and castings.
