Rolling is a bulk deformation process that involves passing metal between two rollers to reduce the thickness of the metal. There are different types of rolling processes, including hot rolling where metal is heated and rolled to form thinner cross sections, cold rolling which increases hardness and strength but decreases ductility, and ring rolling which is a specialized hot rolling process that increases the diameter of rings.

2. Rolling is a (bulk deformation process) It
consists of passing metal between two rollers.
Reducing the metal thickness.

3. Hot rolling is a hot working process where
large pieces of metal, such as slabs or billets, are heated
above their recrystallization temperature and then
deformed between rollers to form thinner cross sections.
Cold rolling increases the hardness and
strength of a metal, it also results in a large decrease in
ductility. Thus metals strengthened by cold rolling are
more sensitive to the presence of cracks and are prone to
brittle fracture.

4. Roll bending produces a cylindrical
shaped product from plate or steel metal.

5. Is a process in which the metal sheet or strip
stock is placed between rollers and then compressed
and squeezed. The amount of strain generated
determines the hardness of the finished product.
There can be numerous types of cold rolling mill,
which can produce different types of rolled product,
with thicknesses as low as 0.05mm

6. Ring rolling process is a specialized
type of hot rolling that increases the
diameter of a ring.
