mediate rolling mills, the pass line was bent again by 90 degrees to be led to an intermediate water cooling box that was installed to control the property of scale, and then on to the finishing mill. A looper is needed between the newly installed intermediate mills and the finishing mill to absorb speed variation. Since the pass line is set

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 ...
A pass-line adjusting mechanism is disclosed in association with the chocks of the lower back-up roll of a four-high rolling mill. The adjusting mechanism includes an axially slidable adjusting member having vertically stepped surface portions corresponding to each lower back-up roll chock, and an inverted channel-shaped support member interposed between the chocks and adjusting member.

Factbox 1 ABB and rolling mills Footnote 1) A pass is one deformation step consisting of the different phases threading, rolling at constant speed, deceleration and tailout of the strip through the mill. A pass schedule is a series of values for the pass, such as thickness, speeds and forces presets.
Optimal pass-scheduling on cluster-type cold rolling mills, use to process flat metals, presents added challenges over conventional (vertical-stack) mills due to the …
This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold rolling mills. The final chapter explains the purpose of roll pass design to ensure the …
Cold Rolling Mill for Aluminium Sheet ... 7- Reduce the roll gap by one unit per pass and repeat steps 3-6 for the remaining four passes. Fig 2: Estimating the coefficient of friction: 1- With a new sample, record the initial thickness. 2- Measure the roll radius.
The conventional rolling mill stand besides the roll stand consists of mill spindles, a pinion stand, a gear reducer and a motor. In case of constant pass line, the roll stand slides on the surface of the sole plate. Housing less mill stands are a pre-stressed stand which is …
The rolling is a crucial plastic processing practice, through which it is possible to manufacture long products with different cross-sectional profiles and sizes [].Huang [] suggested that the roll pass design had been studied for centuries; a large amount of various data, as well as the accumulation of the design and operational experience, had led to the progress of rules and …

The roll grooves in a roller and the roll pass sequence in a hot rolling mill are usually designed based on the type of grades and dimensions of the products and the mill capacity. These have been established over the years based on ana-lytical methods. With modern capability of computer based simulation of the hot deformation process, it is ...
In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. …
Our skin-pass mills are designed using finite element modeling to ensure simplicity and optimum performance. Desired surface finish, whether that's rugosity or brightness. Suppressed yield point elongation, enabling the steel to be formed without developing faults. Improved strip flatness.
Hot rolling is among the most widely used manufacturing techniques. However, rolling mills are major resource consumers; thus, urgent rationalisation is required in the relevant industrial systems. Roll pass design (RPD) is a principal factor that determines process efficiency, product quality and resource consumption. Therefore, it is important to optimise RPD including the selection of roll ...
