Effect of microstructure and properties of forgings after final heat treatment
If the forging process is not reasonable, forging defects may occur, including surface defects, internal defects or unqualified performance, which will affect the processing quality of subsequent processes, and some seriously affect the performance of forging, reduce the service life of finished products, and even endanger safety.The influence of forging structure on the structure and performance after final heat treatment is mainly shown in the following aspects.
How are forgings clearly marked
For the control of forging quality, there is a special set of marking method for searching during the production and use.The marking of raw materials should be noted from the beginning.The content of calibration includes material number, batch number of furnace, date of receipt and delivery, code number of supplier, etc.This helps to distinguish whether variation in materials is due to factors in the manufacturing process itself or to factors that are not.The marking of raw materials also provid
The importance of deformation force calculation in forging
Forgings are formed under the action of external forces, therefore, the correct calculation of deformation force, is the basis for the selection of equipment, mold check.Stress and strain analysis on the interior of the deformed body is also indispensable for optimizing the process and controlling the microstructure and properties of the forging.
The importance of using raw materials and improving the quality of forgings
The preparation of forgings before forging includes selection of raw materials, calculation of materials, blanking, heating, calculation of deformation force, selection of equipment and design of molds.Lubrication method and lubricant should be selected before forging.
