In four high rolling mills, there are four rollers rolls in the opposite direction. Two rollers, each are placed on both sides of the metal sheet. Unlike three high roller mills, the metal sheet will pass through only once. If you want to further reduce the sheet thickness, you need to take out the sheet from the machine and feed it again.
