A Simulink and mathematical models have been proposed in this study in order to control the thickness in a rolling mill process. The simulation results show that the thickness oscillation can be manipulated with high accuracy by using NARMA-L2, since it can remove the non-linearity of servo system and other disturbances complexities. The …

Simon has spent 25 years working in the field of hot rolling of sections, rails and sheet piles. In 2006 he was central to the Scunthorpe long rail rolling project with the development of the new Roll Pass Design for a seven stand continuous finishing mill. From 2009 to 2012 he was the Heavy Section Mill Process Director at Danieli and in 2012 ...
In the range 50 - 55° they are used for large back-up rolls, around 80° for small back-up rolls in cold rolling, and 90 - 100° (fully hardened) for work rolls in cold rolling. A typical …
One key condition is a perfect pass design in the rolling mill. The paper deals with the models for a pass design calculation as well as a calculation of roll force and power demands for...

Energy-saving AC drive technology for main and coiler motors. Achenbach OPTIROLL®i3 System for integrated, digital, modular designed automation.
This rolling mill is mainly used to produce heavy-wall pipes with large diameters and special section pipes. Based on the features of forging and rolling, it can also be used to produce alloy steel pipes. The specification range of outside diameter is within 114–665 mm and wall thickness is within 2.5–100 mm.
The conversion allows the standard 4-high rolling mill design to roll lighter gauges without the many deficiencies of a 4-high rolling mill. Our current equipment include: 26" x 72" 2-High w/Roll Bend 3.5" x 16" x 20" American 4-High w/Terminal Equipment 16" x 20" x 48" 4-High 2/3,000 HP DC Drives
Rolling mill rolls and roll bearings base are the core parts of the whole working stand of the rolling mill, and the roll is the main part of the direct rolling mill. In the process of rolling, the roll contacts with the workpiece directly, forcing the plastic change of the workpiece. At the same time, the roll bears a huge rolling pressure, and the stress …
Aksenov et al. [4] tried changing the caliber design to obtain uniform distributions of the rolling force and torque. However, avoiding ductile damage inside the workpiece has not been a primary focus in the process design of caliber rolling yet. ... Rolling mill Bühler VRW-400 and the four passes of the reference process in the …
We have proposed a method of numerical simulation for hot caliber rolling, in which the deformation of the material is analyzed by the conventional three …
This obviates the transport of material from one side of rolls to the other after one pass is over. 3. Four High Rolling Mills. Four High Rolling Mill. As shown in the above figure, this mill consists of four horizontal rolls, two of smaller diameter and two much larger ones. The larger rolls are called backup rolls.
The project consisted of replacing the following control systems on an existing two-stand aluminum cold mill: Feedforward and feedback automatic gauge controls (AGC) Interstand tension control (ITC) Automatic sheet flatness control (AFC) Mill setup. Entry and exit x-ray thickness gauge interfaces. Mill stand hydraulic actuator sequencing.
The simulation calculations conducted with the mathematical model unambiguously show that the roller's rotation around a fixed point considerably …

The advent of automated, high-speed tandem coldrolling mills for wide strip has reduced the available manpower for observing and controlling strip shape (or flatness) after each stand. Consequently there has been an increased emphasis on selecting ground roll cambers which minimise manual adjustments of coolant flowrate and roll bending …
The design and configuration of rolling mills are tailored to cater to particular types of metals, dimensions, and shapes. Similarly, switching to different materials or adapting to evolving market demands …
Pass design of caliber rolling is necessary to obtain products of high accuracy and high quality. Accuracy means the accuracy of the shape of the final products and quality …
Shape rolling is widely employed in the production of long workpieces with appropriate cross-section profiles for other industrial applications. In the development of shape rolling systems, roll pass design (RPD) plays an essential role on the quality control of products, service life of rolls, productivity of rolling systems, as well as energy …
1. Vertical Mill Stand The up-drive type consists of a roll stand, mill spindles, a vertical gear reducer with a pinion stand and a motor. The gear reducer and motor are installed on a concrete frame to protect them from roll cooling water and mill scale. A lifting device is installed under the roll stand to adjust the caliber position to pass ...

The advantages of Rolling process are as follows. By rolling, uniform dimensions of the components can be obtained. It uses the same tool in the sense, the same rollers are responsible for the production of various components. Close tolerance is possible for the components in the rolling. high-speed production takes place in the rolling.
Before you can design the rolls, you must determine the proper number of passes and the rolling mill. After calculating the estimated strip width, you can develop the flower by using the arc and straight …
