  • 4 High Rolling MillElement

    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 reversing cold rolling mill which takes relatively inexpensive capital investment is put into use. The reversing cold rollin g mill is used mainly for producing coils of normal carbon steel in emerging countries and is used for producing small lots of variet y coils of high-grade steel or special steel in advanced countries.
