Strip shape, also referred to as strip flatness, is becoming more of a concern for all involved in the rolling mill industry. Poor strip shape can increase scrap since products made from strip with poor shape can be defective.
Rolling Practice and Rolling Tolerances Universal mills are used for rolling W, S,C, MC, S, L and shapes. The thickness of the flange and the web may be HP changed with corresponding changes in the beam depth and flange width. The thickness of the web may be changed with a corresponding change in the flange width. All other dimensions
With a Pepetools combination mill it's simple to make your own ring shanks in whatever size and shape you require. Pepetools have also recently introduced the "comfort" roller which has round and oval grooves.
The shape control technologies of a hot-rolled steel strip began with the crown control, or profile control. Hot rolling mills of high crown/shape control capacities such as a 6-high mill and a cross roll mill were developed, and highly accurate shape/crown control was realized by adequately setting and dynamically controlling the posi-

Shape-meter System with direct contact force sensor Measuring roll has high reliable magneto-elastic force sensor in roller shaft every 90 deg. There are four snapshots of the flatness profile for every revolution. From Magneto-elastic force sensor, Shape-meter System can measure force distribution with width direction and then evaluate
HOT ROLLING PRACTICE – An Attempted Recollection Saral Dutta. B. Tech. (Hons.), I.I.T. Executive Director, ISP & RMD, SAIL (Retired) Rolling is a metal forming process in which metal stock is passed through a pair of rolls. There are two types of rolling process - flat and profile rolling. In flat rolling the final shape of the product is either
Figure 15: General Mill Layout (example Reversing Cold Mill) 5.2 Shapemeter Rolls . Usually, during the cold rolling process, the strip is rolled under high tension. This high strip tension compensates for differences in length or shape defects so that the strip appears to be flat during the rolling operation. As soon as the strip is uncoiled
and cold rolling mills. The system provides: – Width and shape (sables, necking) – Over-all length – Flatness, waviness – Crop shape at front and rear – Thickness Width is measured through two lateral laser triangulation sensors with high resolution. Special laser optics (patented) overcome the problem of vertical material movement.
To promote the optimization of shift roll shapes, the roll shape of each rolling mill plant or rolling mill stand can be optimized, and the shape of shift rolls of a rolling mill stand can be optimized one by one so that the control effect for the strip width with a higher production ratio becomes greater.

Vertical roller mills versus ball mills Soeren Worre Joergensen MSc, General Manager, Engineering, Grinding Technology F.L. . 2 ... As shown in Figure 1, the rollers of the OK mill are spherical in shape with a groove in the middle. The table is also curved forming a wedge-shaped compression and
Roll Forming Companies List Products Produced. Examples of common roll formed products include: angle irons, aluminum angles, steel angles, metal channels, metal trim, metal wall panels and metal rings.Roll formed products may also be custom made for specialty applications, like bus industry seat tracks.
These grooved or combination rollers come in an assortment of shapes - V shapes, round and ovals. Grooves in the top roller correspond with grooves in the lower roller, and typically you will see several grooves in diminishing sizes. The main use for these grooves is to convert rough or cast material into useable bars and wire.
The Horning Stationary Roller Mills are built to crack corn with the highest quality on the market. Efficient and tough, they'll keep you rolling for years. Choose from a …
In order to analyze the influence of technical parameters on work roll axial force of four-high continuous variable crown (CVC) mill, the deformation analyzing model with top roll system and strip was established based on influence function method. Then a CVC work roll curve designing scheme was proposed and it was carried out on some cold rolling mill considering the …
reversible, rolling in an intermediate mill and in a finishing mill, possible followed by some kind of heat treatment. For steel qualities that can be deformed at higher speeds without problems, some of the last passes can be performed in a wire block. The difference between shape rolling and hot strip rolling is that instead of flat rolls, the ...
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.
CNP® Mill can control crown and flatness by shifting work rolls with a special curved roll profile along the work roll barrel. For further information, refer to "IHI Shape Control Equipment for Strip and Plate Rolling Mill," a paper appearing in the IHI Engineering Review. PFSU predicts crown and flatness based on these
Shaping Machine Manufacturers. Shaping machine works on one return crank mechanism that gives tool reciprocating motion. It's a base, column, saddle, clapper box, cross rail, reciprocating ram holding the tool adjustable for cutting stroke, tool head at front of the ram etc.
Based on the shape detecting principle and the DSP (Digital Signal Processing) technology, a high-precision shape detecting system of cold rolling strip is developed to meet industrial application. It was successfully used in Angang 1250 mm HC 6-high reversible cold rolling mill. The precision of shape detecting was 0.2 I, the shape deviation was controlled within 6 I after …
