increase in length. This part of the hot rolling process is also called a Breakdown rolling process. Following the reversing mills, the slabs are fed to a continuous hot mill where the thickness is further reduced. The metal, called reroll or hot band, is edge trimmed and rolled into a coil and is ready to be transferred to the cold mill.

The Rolling Process is a widely used manufacturing technique in the metal industry that involves passing the metal through a pair of rotating rolls to reduce its thickness and change its crosssectional shape. This process is highly versatile and capable of producing a wide range of metal products, such as sheets, plates, bars, and structural shapes, with precise dimensions and surface finishes.

Metal Rolling Process. Metal rolling is a metal forming technology in that we shape starting metal parts or we reduce the thickness of that metal with the action of two or more opposing roll sets. Also, these rolls apply pushing and compression force on the thicker metal to obtain more thin metal parts.

Aluminium rolling lubrication: Hot Rolling. During the hot rolling process, lubrication and thermal control of the work rolls are achieved by spraying oilinwater emulsions onto the rolls in controlled patterns. The emulsion also removes any loose debris from the roll bite area and carries it to the filter where it is removed.

In the hot rolling mill, the metal's grain structure changes. The grain structure that plays a vital role gets refined. The usual coarse grain gets transformed into finer grains which alters the properties of the metal. Change In Porosity. The hot rolling mill and its process ensure that the porosity of the metal is removed and eliminated.

Fig 3 Rolling process concepts In metal rolling, the arc of contact between the rolls and the metal is a part of a circle. The coefficient of friction is constant in theory, but in reality it varies along the arc of contact. The metal is considered to deform plastically during rolling. The volume of metal is constant before and after rolling.
