Choke on opposite sides of the load, if this action will not damage the load and maintain load control. Always use a choker hitch when turning a load. If the sling is not rigged properly, the turning action will loosen the hitch, resulting in load slippage. Place sling eyes on top of the load, pointing the opposite direction of the turn.

A fourhigh mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils. Historically mills were classified by the product produced:
Rolling mill consisting of three rolls or known as 3 High rolling mill is typically used for performing multiple reduction passes by wrapping material around the center mill roll and performing another reduction on the opposite mill roll pair. 3 High mill can also be used with varying mill roll sizes to induce a specific percentage of reduction of material on a single side of the work piece.

The history of the Sundwig 20high rolling mill begins in the first half of the last century, when Sundwig developed a multiroll cold rolling mill in 1930. Just a few years later, the first alligatortype 20high rolling mill was built, followed in 1958 by the first 20high rolling mill .
In order to analyze the influence of technical parameters on work roll axial force of fourhigh continuous variable crown (CVC) mill, the deformation analyzing model with top roll system and strip was established based on influence function method. Then a CVC work roll curve designing scheme was proposed and it was carried out on some cold rolling mill considering the requirement of ...
stockpile, the varying size and hardness of the mill feed material affects the residence time in the mill and the power drawn. When the load becomes critically high, the feed needs to be cut in order to "grind the mill out". This dramatic change in mass flow and particle size is passed to the downstream processes, causing
A ZMill or Sendzimir Mill is a machine for rolling steel. Unlike a traditional rolling mill this 20high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality.
