It is very typical mill. The sendzimir mill is a modification of the cluster mill with 20 rolls. which is very well adapted to rolling thin sheets or foil from high-strength alloys. Hard materials, including stainless steels, titanium alloys and nickel alloys may be rolled in these mills. ADD COMMENT EDIT Please log in to add an answer.

The cold-rolling of metals has played a major role in industry by providing sheet, strip, foil with good surface finishes and increased mechanical strength with close control of product dimensions. Cold rolling, in the everyday sense, means rolling at room temperature, although the work of deformation can raise temperatures to 100-200 C.

Steel is produced in several stages in Mini Mills. First, Ferrous scrap is refined and melted in an Electric Arc Furnace. Next, the molten steel is often further refined applying a metallurgy process using what is called a Ladle Furnace. Next, the steel is shaped into semi-finished products such as slabs, blooms or billets.

The forging process is entirely different from the casting (foundry) process, as metal used to make forged parts is never melted and poured into a mold (as in the casting process) but rather is first cast as an ingot or Billet and is then heated to be Forged or Pressed, pounded or squeezed in order to achieve the desired shape and size required.

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.

Steel Rolling. Abstract: Rolling is an indirect compression process. Normally the only force or stress applied is the radial pressure from the rolls. This deforms the metal and pulls it through the roll gap. The process can be compared to compression or forging but differs in two respects in that compression takes place between a pair of ...

The basic control strategy is thickness feedback (monitor control) based on the measured thick - ness deviation at the exit side of the mill. The delay time, transport of the strip from the roll gap to the thickness gauge, essentially deter - mines the control system's dynamic response, particular at low rolling speed.

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
