Abstract: The invention covers a group gear for the rollers of individual stands, driven by a motor via one common main drive shaft, of a continuous rolling mill, particularly for a wire manufacturing block where the secondary drive speed is picked up by the main drive shaft via the respective bevel gear stage, and then transmitted to the rolling mill shafts.
The proposed method for monitoring fluctuations of load on the drive mechanism of a rolling mill consists in measuring the output signal of the current transducer of the driving motor within the period of the increase of the load on the working rolls of the mil, measuring the output signal of the lowpass filter, which is connected to the ...

The proposed method for diagnosing the bearings of the drive mechanism shaft of a rolling mill consists in repeatedly measuring vibrations of the bearings within the period of the increase of the load at the working rolls of the mill, with a specified time interval between the measurements, determining the natural vibrations and harmonic ...
Jun 13, 1978· BACKGROUND OF THE INVENTION. The present invention relates to a drive mechanism for vertical rolling mills and more particularly it relates to a drive mechanism for vertical rolling mills which itself is provided with a device for mounting a driven coupling on and dismounting it from the neck of a working roll.

grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill .
Test data from an actual cold rolling mill verified the accuracy of the model. The model was shown to be capable of simulating the mutually coupled and affected mechanism between a mill and its drive system. Keywords Nonlinear coupling dynamic characteristics, cold rolling mill system, different rolling parameters, fault diagnosis
The working roll of the rolling mill is driven by a series of drive mechanisms through a motor. The rolling pieces are processed by two opposite rotating rolls under pressure to produce plastic deformation. The 4hi rolling mill completes this process by working rolls. The work roll includes two kinds of motion: rotating and moving.
Eisenbeiss has developed special gear systems for cold rolling mills that enable closer axle spacing to achieve small roll diameters. Thanks to the power density of the gears it is possible to process high tensile steel and aluminium products.
A machine used for rolling metal is called rolling mill. A typical rolling mill consists of a pair of rolls driven by an electric motor transmitting a torque through a gear and pair of cardans. The rolls are equipped with bearings and mounted in a stand with a screwdown mechanism.
1. Vertical Ring Rolling Mill Vertical Ring Rolling Mill, or VRRM for short, being discussed here, was a machine that was developed in Japan some decades ago, and had a ringforming roll configuration which was different from the one that is seen with the currentlyconventional horizontal (radial/axial) type ring rolling mill.
The two high reverse roll which have incorporate a drive mechanism and work is continuously through back and –forth passed between the rolls. That are usually employed for initial rolling of an ingot. Three high rolling mills or triple roll: triple roll or three rolling mill
Rolling mill vibration is a worldwide problem, although it has been found that the mill structure defects are the main cause of vibration, but the inhibition measures are difficult to implement. So we discussed the rolling force parameters influence on rolling mill vibration and suppression measures from rolling technology in this article.
HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a .
Jul 20, 2015· Rolling Mill Guide Equipments . In hot rolling mills for long products, guide equipments guide the rolling stock at the entry and the exit of the roll pass so as to have smooth rolling of the rolling stock. The guiding equipments are to be sturdy, accurate and stable.
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. Rolling mills often vary in .
