The processing of Forged parts, namely forging, is the use of forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain certain mechanical properties, certain shapes, and sizes. The processing method of Forged parts consists of one of the two major components of forging (forging and stamping). The smelting process can be eliminated forging-cast defects such as loose, optimized microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of Forged parts are generally better than castings of the same material. For the important parts of related machinery with high load and severe working conditions, Forged parts are mostly used except for simpler shapes that can be rolled, profiles, or welded parts.

l Precautions for the production of Forged parts.
The initial recrystallization temperature of steel is about 727°C, but 800°C is generally used as the dividing line, and the temperature higher than 800°C is hot forging; the temperature between 300 and 800°C is called warm forging or semi-hot forging, and forging is carried out at room temperature. It is called cold forging. Forged parts used in most industries are hot forging. Warm forging and cold forging are mainly used for forging parts of automobiles and general machinery. Cold forging and warm forging can effectively save material.
Compared with castings, metal after forging can improve its microstructure and mechanical properties. After the hot forging method for forging deformation process, deformation and recrystallization of the metal, so that the original coarse dendrite and the grain refinement becomes a columnar crystal, the size of equiaxed uniform recrystallized structure so that the original loose segregation and forgings, porosity, slag, and other compaction and welding, the tissue becomes tighter, forging and plastic improved mechanical properties.
The mechanical properties of castings are lower than the mechanical properties of Forged parts of the same material. Further, the forging process can ensure continuity of the metal fiber structure, the fiber structure remaining consistent with the shape of forging the forging, the metal flow lines complete, ensures parts with good mechanical properties and long service life. Using precision forging and cold extrusion. Temperature extrusion process for producing forging the like. are unmatched by castings
A forged part is an object in which a metal is subjected to pressure to shape the required shape or suitable compression force through plastic deformation. This force is typically achieved through the use of a hammer or pressure. The Forged parts process creates a fine grain structure and improves the physical properties of the metal. In actual use of the parts, the correct design allows the pressure in the main flow direction of particles. Cast metal profile is obtained by various casting methods, i.e. melting of liquid metal by casting, injection, suction, or another casting method for pouring into prepared molds to roll out after cooling, washed, re-processing. Processing, To obtain objects with a certain shape, size, and performance.
Workers are exposed to high temperatures while air and heat radiation, resulting in heat buildup in the body. Heat plus metabolic heat can cause heat dissipation obstacles and pathological changes. Perspiration 8 hours will vary with changes in the environment stingy, physical exertion, and ability to adapt to the heat. Generally between 1.5-5 liters, or even higher. In smaller forging shop or away from heat sources, Béja the thermal stress index typically 55-95; but in a large forging shop, a heating furnace, or near the working point of the drop hammer may be as high as 150 to 190, and heat is likely to cause lack of salt Convulsions. In the cold season, exposure to small changes in climate and environment may contribute to its ability to adapt to a certain extent, but fast, too frequent changes might be a health hazard.
Forged parts are widely used, such as joints, valves, chains, mining equipment, food equipment, auto and motorcycle parts, environmental protection equipment, rail transit, etc. If you need Forged parts and more CNC Turning parts, please visit our official website to purchase them.
