rolling mill producing wide steel strip using one profile meter MPP in Quality Section at the tandem line and pickling line and the second in section of thin rolled strip – being in this case a follow up process. For this reason it is not possible to generalize obtained information and use results on all types of material and production ...
Strip shape control (SmartCrown), as described in detail below: Mill stabilizing device (MSD) At today's demanding condition, maintaining stable operation of rolling mill is becoming difficult. MSD is a hydraulic cylinder installed to mill housing window and press a roll chock against the .
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 tension and the tension deviation for each rotor are determined from the load applied to
17-4-2001 · A method and apparatus for rolling a strip by a rolling mill wherein one back-up roll of the pair of back-up rolls is a variable crown roll having a single oil chamber and the other back-up roll is a variable crown roll having a plurality of oil chambers. The strip shape is detected by a shape meter and ... in a rolling mill ...

Abstract: Shape has a significant impact on the good quality of follow-up deep-processed steel products. But it is difficult to detect, so a shape detecting equipment of cold rolling strip is developed to meet industrial application, which mainly consist of the shape detecting roller, the collecting ring, the DSP shape signal processing board and the shape control model.
CONTOUR CHECK SHAPE has proven itself in hot rolling of long products and is an essential part of the rolling process in many factories. It checks hot and cold steel profiles with the help of three-dimensional surface reconstruction.
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.

The flatness is defined in I-units One I-unit corresponds to a difference in length of 10 µm per meter of strip length. The levelness describes the topography of the strip surface, i.e. the deviations in height observed when the strip lies on a level surface. The measuring rollers and the VIP08 optical system from Vollmer measure the flatness.

the strip shape is hidden and cannot be measured. Therefore we have developed a strip shape meter that uses a torque meter to accurately measure the width directional distribution of the tension in the rolling direction, which corresponds to the strip shape (Looper Shape Meter, hereinafter referred to as LSM)2-4. This device employs a method ...
forming of H.R. Steel strips into Tubular shape & welding the edges under pressure using high frequency induction heating. The basic raw material for manufacturing of pipes is H R Coils. After receiving the raw material in Coil shape these are slitted into various widths .
Tata Steel Legacy of Trust Tata Steel is amongst the top-ten global steel companies with a crude steel production capacity of 26.5 million tonnes per annum (mtpa). A Fortune 500 Company, the Tata Steel Group is the world's second most geographically diversified steel producer, employing over 80, 000 people in nearly 50 countries.

One example of individual customer solutions is that as part of rolling mill modernizations for wedge-shaped strips, we use the inlet-side shape measuring rolls as pivoting rolls for strip centering control. The flatness computer receives the input signals for this from the strip edge detection unit that forms part of the scope of supply.
