Rolling is a (bulk deformation process) Itconsists of passing metal between two rollers.Reducing the metal thickness.
Hot rolling is a hot working process wherelarge pieces of metal, such as slabs or billets, are heatedabove their recrystallization temperature and thendeformed between rollers to form thinner cross sections. Cold rolling increases the hardness andstrength of a metal, it also results in a large decrease inductility. Thus metals strengthened by cold rolling aremore sensitive to the presence of cracks and are prone tobrittle fracture.
Roll bending produces a cylindricalshaped product from plate or steel metal.
Is a process in which the metal sheet or stripstock is placed between rollers and then compressedand squeezed. The amount of strain generateddetermines 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
Ring rolling process is a specializedtype of hot rolling that increases thediameter of a ring.
