What is the difference between a rolling mill with reduction and
a rolling mill without reduction?
A rolling mill with no reduction means that when you turn the handle
round once the rolls will go round once. However, a rolling mill
with reduction lets say 4-1 means that you will have to turn the
handle 4 times for the rolls to go round once and a reduction of
6-1 means you have to turn the handle 6 times for the rolls to go
round once. Etc etc.
It is a lot easier to roll out material with reduction. It reduces
the amount of strength that you have to use to roll out material
through the rolls. However, you will have to turn the handle more
times than if you had no reduction Which potentially could mean
the rolling process could take a little longer when rolling out
smaller/easier work. I.e.: you are cranking the handle a lot more.
Some people still prefer the rolling mill with no reduction if
the work they are doing is not that big or if they are only using
it infrequently.
