Question
explain part c) please
In the chapter, it was stated that spreading in flat rolling increases with (a) a decreasing width-to-thickness ratio of the entering material, (b) decreasing friction, and (c) a decreasing ratio of the roll radius to the strip thickness. Explain why.Explanation / Answer
See,the explanation is very clear, spreading in flat rolling increases with increase in strip thickness as more the strip thickness,the more flat rolling increases due to less friction while moving and weight term adds to rolling here. =>spreading in flat rolling is directly propotional to strip thickness.....(A) and spreading in flat rolling decreases with roll radius which is a big factor for increasing the friction and hence =>spreading in flat rolling is inversely propotional to roll radius......(B) combining both A and B we have spreading in flat rolling increases with a decreasing ratio of roll radius to the strip thickness
