Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was the first to ...

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
Upper roll chock has a support with an additional lining for holding up the top roll when the rolling mill is idling. In a four high mill, there are four types of roll chocks namely (i) top back up roll chock, (ii) top work roll chock, (iii) bottom work roll chock, and (iv) bottom back up roll chock.

1 The number of rolling passes can be freely selected according to the rolling size and shape. From 2 to 12 rolling passes can be selected with the HV shifting reverse mill, and 2 or 4 passes with the H shifting reverse mill. 2 It can contribute to chancefree rolling that enables rolling at a number of sizes from a pair of rolls.
In reversing cold mills the tension reels are placed on both ends of a single or twomillstand arrangement. Due to the reversing rolling passes, production efficiency is lower than that of a tandem mill. However, because the rolling parameters can be quickly changed for each coil, reversing cold mills are especially suitable for the smalllot ...
The whole bar rolling mill line adopts full continuous rolling and nontwist rolling, and the roughing mill and intermediate mills adopt microtension rolling. After the 12th rolling mill, vertical loopers are set up between the stands to implement tensionfree rolling, thus producing highprecision products.
At the reversing mill, rolling speed, roll bite, and coolant flow may be optimized only with a precise realtime knowledge of metal temperature. The low and highly variable nongreybody emissivity character associated with this complex aluminum process dictates the use of the most sophisticated multiwavelength infrared pyrometers as the ...
