How to selection of forging ratio?
As the forging ratio increases, the internal pores are compressed and the as-cast dendrites are broken, resulting in a significant improvement in the longitudinal and transverse mechanical properties of the forging. But when the elongation forging section ratio is greater than 3-4, as the forging...Read more -
What is the difference between rolled and forged shafts?
For shafts, rolling and forging are two common manufacturing methods. These two kinds of rolls differences in production process, material characteristics, mechanical properties, and scope of application. 1. Production process: Rolled shaft: The rolling shaft is formed by continuously pressing a...Read more -
