When cold rolling thin steel strips with high tensile strength, reversible cluster mills are used. The customer's demands are high on the products flatness, which is controlled by the different flatness actuators that the mill is equipped with.
shape of I-UNIT (e Dut) and the difference in load between rotors (Df) respectively. Dut: Difference in unit tension in the strip ... shape control that has a closed loop of a shape roll and a rolling mill as shown in Fig. 9. This has enabled high-speed and stable rolling without relying on operator skills. 3.1 Shape analysis Figure 10 shows the concept of shape analysis. The average rolling ...
The shape meter has good performance and stability, which can effectively avoid the scratch of steel strip surface, accurately detect real online strip shape and provide accurate online shape datum for shape control system. It was applied in 1250 mm cold rolling mill, the actual industrial tests prove that the shape signal was stable and reliable, met the harsh condition and the online ...
by: R. V. Singh Abstract: Aluminium Rolling has a very short history of about two centuries. The technology of rolling has matured and stabilized in the last decade or so, with sophistications resulting in higher degree of refinement and richness of final product.

Acta Polytechnica Hungarica Vol. 12, No. 6, 2015 – 93 – Hot Rolling Mill Hydraulic Gap Control (HGC) thickness control improvement Peter Kucsera*, Zsolt Béres**
Introduction 1 Cities in redevelopment, high-rise buildings under construction, freeways undergoing modernization – these and many other projects call for wide flange shapes.
The invention of the rolling mill in Europe may be attributed to Leonardo da Vinci in his drawings. The earliest rolling mills in crude form but the same basic principles were found in Middle East and South Asia as early as 600 BCE.
Efficiency thanks to flat strip . The use of flatness measurement alone without control already achieves a noticeable increase in productivity because strip breaks can be effectively prevented or the mill can be operated at the maximum possible speed for the particular unflatness.
During a metal rolling operation, the geometric shape of the work is changed but its volume remains essentially the same. The roll zone is the area over which the rolls act on the material, it is here that plastic deformation of the work occurs.
Rolling of Metals • Rolling –reducing the thickness or changing the cross-section of a long workpiece by compressive forces applied through a set of rolls
Shape control systems supplied by ANDRITZ Sundwig are used in most rolling mill types in the steel, stainless steel, and nonferrous metal industries. Shape control systems are also used in tension levelers for controlling the strip shape.
Shape-meter System with direct contact force sensor ... Force Sensors for Rolling Mill Tension-meter It is used stainless steel for high corrosion resistivity. It has mechanically high performance for overload, shock and impact. Remarkably High spring constant, Wide measurement range, high reliability No drift, No recalibration, No Failures Magneto-elastic force technology Roll Force Sensor ...
November 2014 General Notes - 4 Nucor-Yamato Steel Rolling Practice and Rolling Tolerances Universal mills are used for rolling W, S,C, MC, S, L and shapes.
APFC controls the entire length of strip profile and shape in the hot rolling finishing mill by means of high-precision setup functions and dynamic control (dynamic profile setup, dynamic shape control).
marketing contact type inline strip shape meters for hot rolling in order to enable continuous accurate measuring of strip shape during rolling and improve strip threading stability on hot strip mills. The inline strip shape meter is designed to accurately measure the shape of a strip, even under a harsh, hot, humid and dusty environment. This shape meter consists of seven segmented rolls ...
The Air Bearing Shapemeter, provided by Primetals Technologies, is designed to provide accurate on-line shape measurement of rolled metal sheet and foil material.
Sendzimir's Shapemeters. T. Sendzimir, Inc. offers two shapemeter designs: the first, patented in 1994, utilizes a fixed (non-rotating) shaft that spans the width of …
In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills.
MS Angles are L-shaped structural steel represented by dimension of sides & thickness. For e.g. 50x50x6 means, both the sides of angles are 50mm & thickness is of 6mm.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.
09.08.2013· 1. Introduction. In the steelmaking industry, shape is a key characteristic to determine the quality of outgoing products of rolling mills and downstream manufacturing lines.
Stressometer ® Systems Make the difference High performing flatness measurement and control is a critical success factor for flat rolling mills. It is the difference between
Flatness measurement using shape-rolls has been used in cold rolling mills for a long time. The benefit is obvious since the measured The benefit is obvious since the measured flatness profile can be used directly to control roll bending, tilt and cooling profile.
Rolling – The important parameters for rolling in the roughing, intermediate, and finishing group of stands in the rolling mill are temperature, percentage of …
