Feet to mm How to convert millimeters to feet. 1 millimeter is equal to 0.00328084 feet: 1 mm = (1/304.8) ft = 0.00328084 ft. The distance d in feet (ft) is equal to the distance d in millimeters (mm) divided by 304.8: d (ft) = d (mm) / 304.8. Example. Convert 20 millimeters to feet: d (ft) = 20mm / 304.8 = 0.065617ft. Millimeters to feet ...
The cluster mill that this study aims is a 20-high reversible mill. With reversible mills means that once the strip has been coiled from the decoiler to the recoiler, the rolling direction is reverted and the decoiler becomes recoiler and vice versa. The mill contains of an upper and lower mill housing of rolls, see figure 1.

2. Three-High Rolling Mills: In this mill, the three rolls stand in parallel one by others. The rolls are rotating in opposite directions. In this mill, between the first and the second rolls, the material passes. If the second roll rotates in a direction then the bottom roll rotates in another direction.
temperature or at intermittently high temperature. For a prolonged service life, such as 20 years, plain carbon steels are usually limited to a maximum operating temperature of 750°F (399°C); the ½% molybdenum alloy steels to approximately 850°F (454°C); and the stainless steels to considerably higher temperatures depending upon the type used.
2 High Rolling Mill - Element. 2 High Rolling Mill. Rolling mills consisting of two rolls or known as a 2 High rolling mill is used for anything from temper pass to breakdown of material. The 2 High rolling mill typically have larger diameter work rolls that are positioned with actuators that either have: Hydraulic. Pneumatic. Electro-mechanical.
tensile specimen of the metal with gage length = 100 mm is stretched to a length = 157 mm. Determine the flow stress at the new length and the average flow stress that the metal has been subjected to during the deformation. Solution: ε = ln (157/100) = ln 1.57 = 0.451 Flow stress Y f = 850(0.451) 0.30 = 669.4 MPa. Average flow stress Y f = 850 ...

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: Minimum number of passes required.
Both the CP and PCP hot bands were annealed at 900 °C for 7 min and pickled, and were cold rolled to 1.0 mm using a reversible laboratory cold rolling mill with a roll diameter of 110 mm. Finally, the cold rolled sheets were heated to 900 °C and held for 2.5 min for full recrystallization annealing.

in the U.S.A. 3 mm 2/s oils became standard while, in the U.K., 7.5 mm /s oils were used. AeroShell Turbine Oil 300 and AeroShell Turbine Oil 750 respectively were developed to meet these two separate requirements. The situation persisted for some years until 3 mm2/s oils were required for use in British pure jet engines.
