Nov 22, 2013 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 work roll. The OD of the work rolls is between 208 to 225 mm or 145 to 155 mm, while the backup roll may be 575 to 610 mm. The length of both rolls are 700 mm, hence it can accommodate coils having width upto 630 mm. The mill is reversible

100 kN. For this, the backup rolls are raised up in the four-high and six-high stands. The necessary roll force is attained solely by means of the work roll bending or, in the case of the six-high stand, by the intermediate roll bending. This, for example, allows the controlled skin-passing of mild IF steels. We make use of CVC plus for the ...
