Hot metal ingot being loaded into a hammer forge A billet in an open-die forging press. Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer) or a die.Forging is often classified according to the temperature at which it is performed:cold forging (a type of cold working), warm forging Forging Book:The Ultimate Guide of Metal Forging (Free Flexibility; hot forging is more flexible than cold forging. This is because customized parts can be manufactured easily. 3. Superior surface finish; this allows for a number of finishing operations such as painting, coating or polishing. 4. High temperature removes any homogeneous substances. This is due to the increased diffusion. 5.

Aug 06, 2020 · Fig 2 Forging pressure for low carbon steel upset at various temperatures and two strain rates. Selection of steels for forging. Carbon and alloy steel ingots, blooms, billets, and slabs for forging are hot rolled or cast to approximate cross sectional dimensions, and hence, straightness, camber, twist, and flatness tolerances do not apply. Forging:Types, Operation, Defects, Advantage Hot Forging:The hot forging is performed at extremely high temperature like (up to 1150 °C for steel, 360-520 °C for al-alloys, 700-800 °C for CU-alloys). This temperature is necessary because when you perform the operation of hot forging, the strain hardening problem comes while deforming the workpiece.

Hot Forging Process - an overview ScienceDirect TopicsForging dies undergo high thermal and mechanical loads. High forging temperatures result in structural changes of the surface area which especially benefit mechanical wear mechanisms (abrasive wear) [1].Furthermore, based on thermal expansion, the temperatures of a hot forging process affect the part accuracy, e.g. at process start, process variation, and process interruption (Fig. 3.2.6.2).

Hot Forging and Hot Forging for Thin-walled Parts

Hot forging, which is different from cold forging and warm forging, refers to heating the metal by gas or electric energy to make the forging temperature higher than the recrystallization temperature of the material itself (generally not exceeding 800 ° C), and then through a pre-designed die forging the metal into a pre-designed shape.
