Production Process of Forged Die Steel Bar

1. Raw material preparation

The raw materials for forging die steel bar are mainly high quality ingots and alloying elements. According to the different requirements of the mold, the factory can choose different grades of steel, such as cold work mold steel, hot work mold steel and plastic mold steel.

2. Melting and casting

Workers will put the selected raw materials into the furnace for melting, control the furnace temperature and melting time. This can ensure a uniform distribution of alloying elements in steel and an increase in purity. After the smelting is completed, the molten steel is poured into the die for cooling to form the ingot.

3. Preheating and forging

Workers preheat the ingot to remove internal stress and improve the plasticity and ductility of forging. The preheated ingot enters the forging press for forging, which is divided into two stages: rough forging and precision forging. In rough forging, the ingot is subjected to initial plastic deformation at high temperatures to eliminate internal defects and improve the structure of the steel. In precision forging, workers will use a smaller forging force and a higher forging temperature, so that the steel is further plastic deformation, forming the required forging shape and size.

4. Heat treatment

The forgings after forging need to be heat treated to improve their structure and mechanical properties. Heat treatment mainly includes annealing, normalizing, quenching and tempering processes. The hardness, strength and toughness of forgings can be achieved by controlling the process parameters of heat treatment reasonably.

5. Subsequent processing

In addition to the above main processes, its production process also includes organic molding, surface treatment and precision processing and other processes. Organic forming refers to accurate forming through molds, which can reduce the amount of processing to a certain extent and improve the accuracy of forgings. Surface treatment includes processes such as rust removal, sandblasting, pickling, and oiling to prevent oxidation and corrosion of forgings. Precision machining is to further improve the accuracy and surface quality of forgings.
