- design a rolling mill arrangement for rolling operation
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 processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.

Such an arrangement is used in mills through which the bar passes once and in open train plate mill. 2: Three high rolling mill: ... Design Principles Common to …
same way as in conventional rolling up to the intermediate rolling mill. Here, after an acceptable section is produced, the slitting operation will start. Before deciding to implement the slit rolling method to an existing rolling mill it is essential to examine the suitability of this mill for the slit roll-ing technology.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
The basic principles of a rolling-mill design are shown in B in the figure. Two heavy bearings mounted on each side of a roll sit in chocks, which slide in a mill housing for adjusting the roll gap with a screw. The two housings are connected to each other and to the foundation, and the complete assembly is called a roll stand.
The number of backup or supporting rolls depends upon the amount of support required for the working (small diameter) rolls. Cluster mill is generally used in cold-rolling operation. The arrangement of cluster mill is shown in Fig. 2.9 (d). Type # 5. Multi-High Rolling Mill:
Continuous rolling processes Mill train designed to have the workpiece enter one pair of rolls before leaving the preceding pair. Semi- continuous rolling process A continuous arrangement for high-production rolling of almost all products requires the construction of long rolling trains and buildings, but layouts can be shortened by a so-called
The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
