In 1886 in the USA, W. Edenborn and C. Morgan were the first to use a high-speed wire coiler with axial feed. The first flying shears were designed by W. Edwards and came into use in 1892 in the USA. In 1897 an electric motor was successfully used to drive a rolling mill in Germany. In 1906 a rolling mill with a reversible electric motor was

Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll - body and necks - have to be considered as normal parts of designed components under high
The performance of a rolling element bearing is a function of the accuracy with which it is made; and the most accurate rolling element bearings are made on machines that use fluid films. In fact, the first machines used to grind rolling element b earing components used hydrodynamic bearings, where high speed relative motion between components caused a film of lubricant to build up between

All of these mills are usually used for primary rolling and the roll diameters range from 60 to 140 cm (24 to 55 in). To minimize the roll diameter a four-high or cluster mill is used. A small roll diameter is advantageous because less roll is in contact with the material, which

Temperature and speed extremes; high and constant shock loads; abrasive dust, aggressive chemicals and high humidity – it's safe to say that few industries can match the extreme operating conditions in steel and other metal mills. These conditions degrade equipment, cause unplanned downtime and make effective maintenance difficult at best. Increasingly stringent environmental and health
American Roller Bearing Company primarily makes heavy duty bearings that are used in various industries in the US and around the world. Not only must our industrial class bearings provide long in-service life from a rolling fatigue criterion, but they must also hold together structurally from impacts, overloads, and occasional high-speed excursions.

row angular contact ball bearings are found predominantly in high speed rolling mills for wire and fine iron production lines. The drive shafts in heavy duty rolling mills have a considerable mass. They were previously normally supported in plain bearings. Now, wear and lubricant requirements are considerably reduced due to the use of special cylindrical roller bearings of split design

The introduction of spherical roller bearings. The mill configuration type of the early mill bearing is different from now; it was mainly use two self-aligning roller bearings and mount on the same roll neck side by side. This configuration type basically meets the conditions of production then and rolling speed is up to 600rpm. But as speeds increasing, the drawback is the more prominent: the

Roller bearings have higher load capacities than ball bearings for a given size and are usually used in moderate speed heavy-duty applications. The preliminary types of roller bearings are cylindrical, needle, tapered, and spherical roller bearing. Fig. 1 shows the component of ball bearings and roller bearings, .

In a rod Mill, the pinch roll is used for moving the material further when bar has left the mill stand. The main housing of Pinch roll is made from Cast iron, and fitted with EN – 9 rolls with spherical roller bearing housed in steel chocks. The tap roll setting device consists of screw down screw of EN – 8 with gun metal nut. The top roll
roll speed, m/s (ft/sec). The rolls pull the material into the roll gap through a net frictional force on the material. Thus, the net frictional force must be to the right in Fig. (5-3 b). This also means that the frictional force to the left of the neutral point must be higher than the friction force to the right. Although friction is necessary for rolling materials (just as it is in driving
