4 hi mill cold roll flow chart

Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses Through the use of larger backup rolls the issues of roll deflection can be avoided and smaller work rolls can be used This reduction in work roll diameter Reduces overall separating force required for reductions
