Forging is a process of changing the shape of a metal object
(either increasing its length or increasing its diameter) by the application of
local compressive forces with either the target metal at high or low
Thus there are two types of forging according to that
Once the work piece reaches high or low temperature the blows
are delivered with a hammer, either manual hammer or drop hammer. Cold forging
requires more force than hot forging but it increases the strength of the work
piece while hot forging tends to decrease the strength of the workpiece.
Upsetting (Increase Diameter)
Drawing out (Increase Length)
1. Start by
heating the furnace. Use wood for initially starting the fire and then add coal
over it. Use blower for gradually removing smoke from the room and another one
for continuously feeding air to the burning coal for it to burn quickly.
2. Put the
work piece in the furnace. And wait for it to become red hot then take it out
of the furnace and onto the anvil.
3. Apply force
with a hammer with planer in between the work piece and hammer.
4. Soon the
work piece will cool down and will need to be heated again.
5. Thus the
process must be repeated several times before the desired shape of the work
piece is achieved.
6. Be sure to
put out the furnace once the job is done.
7. If using a
drop hammer be sure to read the safety instructions before operating the
Every piece of equipment has its own safety operating
procedures and so does the equipment in the forging shop. So one should go
through it at least once so as to know what is safe.
Since Forging involves dealing with hot objects so one should
be extra careful.
