2 Principles and Applications of Metal Rolling (ii) Shape of the rolled product- flat, sections or hollow sections rolling. (iii) Direction of rolling- lengthwise, transverse, and skew rolling. (iv) Mode of rolling mill operation- continuous (unidirectional), and reverse rolling, where direction of rotation of rolls are reversed. When two rolls of equal diameter and with axis lying in same ...

Mill rolls are driven by large several thousand horsepower motors. Rolling mills are computer controlled with complex automated drive systems. Overall, rolling mill equipment is expensive and can take a long time to repair or replace, even when slight damage occurs. Types of mills include blooming, bar, rod, plate and strip mills.
Roll bearings are to meet the basic need of the rolling mill which is the smooth rolling of the steel products. They are friction reducing devices which provide support to the rolls for effective rolling with minimum of energy loss. The bearings are designed to withstand high rolling loads, heavy shocks, varying speeds, and high temperatures.
