The advantages of forging forging manufacturers

Forging factory forging parts after annealing hardness operation requirements

1. Coarse grains are broken into small and uniform grains, Dongying forging parts, and each other tightly compacted together.

2. The original existing pores or shrinkage is extruded disappeared, the internal organization more closely.

3. Some brittle impurities are crushed, while the plastic impurities with the deformation of the metal and elongated, become a fiber organization, making the material toughness greatly enhanced. Therefore, after forging, the internal organization of the material becomes very solid and significantly improves the mechanical properties. Generally, round or square bars are used as billets for small and medium-sized forgings. The grain organization and mechanical properties of the bar are uniform and good, the shape and size are accurate, the surface quality is good, and the forging parts are quoted, which is convenient for organizing mass production. As long as the reasonable control of heating temperature and deformation conditions, it does not require large forging deformation to forge forgings with excellent performance.

   
   

   Ingots are only used for large forgings. Ingot is cast organization, with large columnar crystal and loose center. Therefore, it is necessary to break the columnar crystal into fine grains and compact the sparseness by large plastic deformation in order to obtain excellent metal organization and mechanical properties.
