Cold rolling - using Roll Coolant - emulsion In this CRM, Cold rolling is done on a Mecon Weanunited PLC controlled 3000 tons/m 4 Hi reversible mill. As the name suggests the 4 Hi mill employs 4 rolls, two these are the work rolls and the other two are the backup rolls. The rolls between which the cold rolling actually takes lace is called the ...
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...

4-High Rolling Mills. Four-high rolling mills can be put in tandem, two to seven stands, instead of a reversing mill. They can be equipped with load cells to tell the separating force and hydraulic or mechanical screw downs, depending if it is hot or cold rolling. Sometimes mechanical screw downs are preferred when there is a risk of fire.

Drawing is a metalworking process that uses tensile forces to stretch (elongate) metal, glass, or plastic.As the metal is drawn (pulled), it stretches to become thinner, to achieve a desired shape and thickness. Drawing is classified into two types: sheet metal drawing and wire, bar, and tube drawing. Sheet metal drawing is defined as plastic deformation over a curved axis.
2.1 Experimental set up. A Hille-100 rolling mill with rolls of 225 mm diameter and 254 mm length, driven by a variable speed DC motor of 75 horse power, was used. The maximum rolling force, torque and speed are 1500kN, 13kN-m and 70 rpm respectively. The sensor roll …
Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
Cluster mill or Sendzimir mill stand – In this rolling mill stand, each of the work rolls is supported by two backing rolls. Cluster mill and Sendzimir mill are used for rolling thin strips of high strength materials and foils [0.0025 mm thick]. The work roll in these mills can be as small as 6 mm diameter – made of tungsten carbide.
