Roll Torque - an overview | ScienceDirect Topics
The speed of the rolling mill is set at 10 rpm, giving a roll surface velocity of 70.69 mm/s. It was found necessary to use guides for the bars, both at entry and exit, in order to minimize sideways bending. The parameters monitored during the experiments include the temperature, roll force and torque. Time-history of the temperature distribution: A typical temperature history during three ...
Calculation of Rolling Load and Torque in the Hot ...
01.09.1962 · This stone presents a completely new approach to the mechanics of the Sendzimir hot planetary rolling mill. Previous work on this subject, by R. Tovini, included determinations for the distribution of the advance of the strip, the draft, the rolling load, the torque and the horizontal backthrust for the whole range of positions which the planetary rolls made, whilst contacting the hot metal.
An investigation on the roll force and torque fluctuations ...
dem cold rolling mill by numerical integration method, whereby the stone deformation zone was divided into small units perpendicular to the motion of the strip. The use of the finite element (FE) technique to predict roll forces and torque has been a popular approach for many researchers, and many commercial FE software pack-ages now exist. Kim, Lee, Shin, and Shivpuri (1992) investigated ...

Dynamic characteristics of a rolling mill drive …
01.01.2000 · From Eq.(11) in Section 3, it is known that the torque amplification factor (TAF) is a function of the normal rolling force and the rolling speed.Assuming the rolling speeds to be 10, 20, 30, 40, 50, 60 and 70 rpm, respectively, the relationship between two stations of the normal rolling force and the torque amplification factors as shown in Fig. 7 are obtained.

A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING …
all rolling schedules including stresses in the roll. As regards “abnormal” rolling conditions - which are more or less very “normal” for rolling mills - roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll
Rolling (metalworking) - Wikipedia
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 ...

Condition Monitoring for Rolling Mills - GfM
Torque measurement at a ring rolling mill. In this specific case, the intention was to modify the product. It was unclear whether the plant sufficiently was dimensioned for it. There were no concrete values for the drive torques and above all for the dynamic components. The application of a torque moment measurement point based on strain gages provided quickly the required information. Ring ...
