Tags Rolling Mills; 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.
A Cold Mill rolls coils of pickled steel from the pickle line at ambient temperature, using coolant oil. The cold mill produces steel and stainless steel and is also used for aluminum, aluminum foil, and copper. There are several types of mills such as 2-High, 4-High, 6-High, 12-High, 20-High, and Sendzimir Mills that have a variety of types of flatness control operations.
Hot Rolled Coil that are cleaned at the pickling line (HRP), is being processed at the cold rolling Mill (total 700,000 tons/ annual capacity) to reduce the thickness to desired values. The homogeneous thickness and high surface quality is maintained at 6 Hi reversing mill with the help of AFC and AGC systems. Cold Rolling Mill 1
A Z-Mill or Sendzimir Mill is a machine for rolling steel. Unlike a traditional rolling mill this 20-high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality.
Four High - For finish rolling of thin gage stock, heavy reductions on nominally thin gage material and precision tolerances. Six-High roll inserts are also available for narrow width ribbon and foil products. Combination- A versatile "two-in-one" type that permits both two-high and four-high rolling in a single mill.

Sep 11, 2014· Customers often ask us about the differences between hot rolled steel and cold rolled steel.There are some fundamental differences between these two types of metal.The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade.
The diameter of the 6-high work rolls amounts to approximately 1:4 in relation to the barrel length. In comparison to a 4-high mill stand, the utilization range is wider. This type of rolling mill is mainly used in offline applications for cold rolling of soft and medium strip and for a wide range of strip widths.
