A series of cold rolling operations are to be used to reduce the thickness of a metal plate from 50 mm to 20 mm in a reversing two-high mill. Roll diameter = 600 mm, and coefficient of friction between rolls and work = 0.15. The specification is that the draft is to be equal on each pass. Determine (a) minimum number of passes required.

Used Rolling Mills. Rolling mills are mainly used in the sheet metal processing industry and in the jewelry processing. Various materials can be used like steel strips, steel sheets, copper, gold, titanium, as well as wire or tubes and profiles. There are two-high or DUO-rolling mills, four-high or QUARTO-rolling mills and reversible rolling mills.
30,000 PSI. As soon as it is cold reduced, and depending upon the amount of reduction, the yield strength can go as high as 100,000 PSI as the material under the work roll hardens. However, as further reduction increases the yield and tensile become about the same and the material will become extremely hard or brittle.
Our in-house cold reduction mills enables us to offer strip quality capabilities in close tolerance of thickness, temper and finish. Waterbury Farrel® 2-Hi/4-Hi Combination Mills may be converted by the removal or insertion of work rolls. This permits great versatility of rolling capability on the same mill.

Cold Rolled Steel Reduction is the process of reducing thickness of hot roll pickled strip to lower target gauge points.. Steel Warehouse uses a reversing mill and a complex automation system to target precision gauge points. Our cold reduction mill services make steel harder and stronger.
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.

Nov 21, 2015· The starting material for cold-rolled steel sheet is pickled hot-rolled coil from the continuous hot-strip mill. The total reduction achieved by cold-rolling generally will vary from about 50 % to 90 %. The reduction in each stand is to be distributed uniformly without falling much below the maximum reduction for each pass.

Jul 16, 2014· Cold rolled is the next step along the line of flat-rolled steel products. The process starts with hot rolled P&O. Hot rolled is processed to a final thickness that is heavier than most sheet products. A cold-reducing process is used, which results in a thinner thickness. The cold reduction starts with tension to the sheet.
