After passing through the rollers in a rolling mill, however, the sheet metal will develop a uniform size and shape. It's important to note that rolling mills support both cold rolling and hot rolling processes. Cold rolling means the sheet metal is pressed between the rollers at or near room temperature. Hot rolling, on the other, means the ...

The cold rolling process is done below the recrystallization temperature of the metal. In this process, the force requirement is much more than the hot working process to pass the metal from the rollers. This process offers a good surface finish. Types of Rolling Mills: There are five rolling mills which are commonly used for rolling metals:

Mark the length of taper on the roll ends. Increase the RPM's on the roll, carefully to a safe speed. Reduce the traverse speed as low as possible. Always start a taper on the face of the roll and traverse outward off the face. Turn the infeed slowly as the grinding wheel moves to the end of the roll.
