Wholesale Metal hot forging manufacturers tell you that there are two types of hot forging process, one is the hot forging of powder preform without pre-sintering, which is called powder forging, and the other is the hot forging of powder preform after pre-sintering, called powder sintering forging. Wholesale Metal hot forging manufacturers tell you that most of them use the latter, and sinter in a protective atmosphere to make it have a certain strength, and then heat the perform to the forging temperature.
Custom Metal hot forging from China tells you that flame heating uses fuel (coal, coke, heavy oil, diesel, and gas) to burn in a flame-heating furnace to produce high-temperature gas (flame) containing a lot of heat energy. Custom Metal hot forging from China tells you that it transfers heat energy to the surface of the blank through convection and radiation, and then conducts heat from the surface to the center to heat the metal blank.
Quality Metal hot forging Wholesale Price tells you that breaking is suitable for high carbon steel and high alloy steel with higher hardness. Quality Metal hot forging Wholesale Prices such as GCr15, GCr15SiMn, GSiMnMo, GSiMnV, and other bearing steels, the heating temperature is 300-400 ℃.
Discount Metal hot forging For sale tells you that cutting and blanking is generally carried out on a shearing machine, which can cut steel billets with a diameter of less than 200mm. Discount Metal hot forging For sale tells you that when the steel billet is cold-sheared, large stress will be generated at the sheared part and cracks will appear. Therefore, high-carbon steel, alloy steel and steel billets with large cross-sectional dimensions need to be preheated before shearing To 350 ~ 700 ℃; for low-carbon steel, medium-carbon steel and other billets with small section sizes can be cold sheared.
Customization Metal hot forging material tells you that the forging process performed above the metal recrystallization temperature is called hot forging. Customization Metal hot forging material tells you that during forging, the deformed metal flows violently, and the contact time between the forging and the mold is longer.
The forging process performed above the recrystallization temperature of the metal is called hot forging. Hot forging is also called hot die forging. During forging, the deformed metal flows violently, and the contact time between the forging and the die is long. Therefore, the mold material is required to have high thermal stability, high-temperature strength and hardness, impact toughness, thermal fatigue resistance and wear resistance, and easy processing. Light-duty hot forging dies can be made from low alloy steels.
