f = (1.05-0.0005t) – for steel rolls f = 0.8(1.05-0.0005t) – for cast iron rolls reducing a round into an oval pass is a 'tri-dimensional process' implying that (beyond the obvious elongation) a circular cross section, for example round 14, is reduced to an almost ellyptical 17x8 cross section.
Double pair mills are usually referred to as roller mills or roller mill grinders. Triple pair (three pair high) mills are used for special applications requiring a finer finished product …
Roller is an important part on the rolling mill of the rolling mill, which uses the pressure generated when a pair or group of rolls roll to roll the steel. It mainly bears the effects of dynamic and static loads, wear and temperature changes during rolling.
• Measure the time between mill shut down to no load amps. For sharp rolls, the amps on the motor should drop immediately within 5 seconds after shutting down. When the rolls are dull the material "floods" the rolls and does not pass through. • Can't pull amps; meaning the rolls are not sharp enough to grab the material and
