Product Parameters

 

The requirement for Raw Material for Forging Riggings

Forging materials are mainly carbon steel and alloy steel of various compositions, followed by aluminum, magnesium, copper,

titanium and the like and alloys thereof. The raw state of the material is the bar, ingot, metal powder, and liquid metal. The ratio of the

cross-sectional area of the metal before deformation to the cross-sectional area after deformation is called the forging ratio.

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 great relationship to improve product quality

and reduce costs. Generally, small and medium-sized forgings use round or square bars as blanks. 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. As long as the heating temperature and deformation conditions are properly controlled, high-

quality forgings can be forged without requiring 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, it is necessary to break the columnar crystal into fine

crystal grains by large plastic deformation, and loosely compact, to obtain excellent metal structure and mechanical

properties.

The powder metallurgy preform which is pressed and sintered can be made into a powder forging by hot forging without flashing.

Forging powder is close to the density of general die forgings, has good mechanical properties, and has high precision, which can

reduce subsequent cutting. The powder forgings have a uniform internal structure and are not segregated and can be used to

manufacture workpieces such as small gears. However, the price of powder is much higher than the price of ordinary bars, and its

application in production is limited. By applying static pressure to the liquid metal poured in the mold to solidify, crystallize, flow,

plastically deform and form under pressure, a die forging of desired shape and properties can be obtained. Liquid metal die forging

is a forming method between die casting and die forging, and is particularly suitable for complex thin-walled parts which are

difficult to form by general die forging. Forging materials in addition to the usual materials, such as various components of carbon

steel and alloy steel, followed by aluminum, magnesium, copper, titanium and other alloys, iron-based superalloys, nickel-based

superalloys, cobalt-based superalloys The deformed alloys are also finished by forging or rolling, except that the alloys are

relatively narrow in plasticity, so the forging difficulty is relatively large, and the heating temperature, opening, and forging

temperature and final forging temperature of different materials have strict requirements.
