Hot forging equipment manufacturers tell you that the forging materials are mainly carbon steel and alloy steel of various compositions, followed by aluminum, magnesium, copper, titanium, etc. and their alloys. The original state of the material includes bar, ingot, metal powder and state. The ratio of the cross-sectional area before deformation to the cross-sectional area after deformation is called the forging ratio. The correct selection of forging ratio, reasonable heating temperature and holding time, reasonable initial forging temperature and final forging temperature, reasonable deformation amount and deformation speed have a lot to do with improving product quality and reducing costs.

General medium/small forgings use round or square bar as the bad material. The grain structure and mechanical properties of the bar are uniform and good, the shape and size are accurate, and the surface quality is good, which is convenient for mass production. Hot forging equipment manufacturers tell you that as long as the heating temperature and deformation conditions are reasonably controlled, forging parts with excellent performance can be forged without large forging deformation.
Ingots are only used for large forgings. The ingot is an as-cast structure with large columnar crystals and a loose center. Therefore, the columnar crystals must be broken into fine grains through large plastic deformation, and then loosely compacted to obtain excellent metal structure and mechanical properties.
The powdered metal alloy that has been carded and sintered is prefabricated. In the hot state, it can be made into powder unforged parts by flashless die forging. The powder of lead parts is close to the density of dry general die forgings. And high precision. Subsequent cutting operations can be reduced. Powder forgings have uniform internal structure and no segregation, and can be used to manufacture small gears and other workpieces. However, the price of powder is much higher than that of general bars, and its application in production is limited.
Applying static pressure to the liquid metal poured in the mold film makes the base solidify, crystallize, flow, plastically deform and form under the action of pressure, and then the die forgings with the desired shape and properties can be obtained. Hot forging equipment manufacturers tell you that liquid metal die forging is a forming method between die casting and die forging, and is especially suitable for complex thin-walled parts that are difficult to form in general die forging. In addition to (usually materials and aluminum, magnesium, copper, titanium, etc. and their combinations, iron-based high-temperature alloys and nickel-based high-temperature alloys)
The deformed alloys of cobalt-based superalloys are also completed by forging or rolling, but these alloys are relatively difficult to forge due to their relatively narrow plastic zone. Hot forging equipment manufacturers tell you the heating temperature and opening forging temperature of different materials. There are strict requirements for the final forging temperature.
