appli ion of rolls for cold roll mill

Roll Mill, Another application of roll mills is to cool materials discharged from an internal batch mixer in a form of large lumps (see Section 42312) The resulting blanket is then transported in the form of strips to the calender or extruder or removed from the rolls as thick sheetsRolling, 's Rolling Mill Rolls Support the World Steel Industry In 1961, became the first company in the world to adopt the "centrifugal casting" method for the production of mill rolls It enables to produce a multi -layer composite rolls , which revolutionized mill roll materialSheet Camber and Cambering of Rolls | Metallurgy, The middle of roll becomes hotter than its ends and hence roll diameter in the middle of roll increas In hot rolling mills this effect is quite pronounced and should be taken into account while calculating the roll camber In cold rolling mills the coolant supply at different points on roll surface may be adjusted to minimize this effectCold Mill Work Rolls, Extensive range This market segment covers forged Work Rolls and Intermediate Rolls for use in Wide Cold Strip Mills of 2-high, 4-high, or 6-high types, including reversing Reduction Mills, Tandem Mills, Double Reduction Mills, and Temper/Skin Pass Mills Our Rolls can be supplied in a number of grades to suit various applications, materials, and rolling conditionsNon, squeezing off oil and emulsions; Our FM®-rolls ensure minimal residual oil levels on strip surfaces in all kinds of cold rolling mills This allows you to run your duo, four-high, Z-high or 20 roll stand at top speed for highest productivity.
