Abstract:
Forging is a process of metal forming in which hot metal at particular temperature is pressed in die at particular pressure. Forging may be carried out in either open or closed die. In open forging, flat dies are used whereas in closed forging, dies of intricate shape are used. Dies are prepared by special steel and suitably heat treated to have proper hardness and toughness so that these are capable of pressing the hot metal in without any deformation in the die during
forging. In open forging, metal takes the shape of the die. The properties of
forged items are considered to be better than other metal forming processes.
Forged items are generally used in automobiles, railways, mining, agricultural
implements, power generation etc. Rolls, shafts, gear blanks connecting rods,
hooks, hubs, brackets, chain link, hand tools, fasteners, pins, hammer, pick axe,
plough etc. are main forged items.
