P. Kucsera et al. Hot Rolling Mill HGC Thickness Control Improvement – 96 – Figure 2 Measured mill stretch characteristic When the mill is loaded, the mill stretch force is measured by load cells or calculated from the measured HGC pressure and can be used to calculate the actual mill stretch.
Aug 26, 2014· • For coldrolling with lubricants, μ ~ – • For hotrolling, μ ~ up to sticky condition. Suranaree University of Technology Tapany Udomphol JanMar 2007 61. Example: Calculate the rolling load if steel sheet is hot rolled 30% from a 40 mmthick slab using a 900 mmdiameter roll. The slab is 760 mm wide. Assume μ =
Equations are derived for the normal roll pressure, specific roll load and torque in hot rolling mills, using the condition for plastic deformation in rolling derived by Orowan, together with von Kármán''s equation of equilibrium. Although applying strictly to the rolling of ideal plasticrigid materials, these equations may be applied to the ...
Rolling processes 51 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
If you''re working in the metalworking industry, even you''re engineers, you will try to find one calculator to help you calculate the weight of various metals and steels including ms plate, gi sheet, structural steel, ms angle, mild steel, steel bar, square tube, angle, aluminum etc. Theoretical Metal Weight Calculator
Feb 02, 2013· Through my website, someone from a manufacturing company asked how to calculate thinning in a sheet metal part made from 2mm thick high strength steel. My response: First, I assume the nominal or expected thickness is 2mm. But this is just the aim thickness. The steel mill is allowed to ship product that has some.
Extensometers are simple, economical sensors attached to rolling mill housings to measure the strain in the housing posts resulting from roll force. Roll force can be derived from these measurements, but due to outside influences, these calculated results can never be as accurate as direct load .
mill. Example:Calculate the rolling load if steel sheet is hot rolled 30 faster speed will result in the media centrifuging inside the mill and virtually no milling or movement of media. Calculating Jar and Jar Rolling Mill Speedthe design of rolling mills, it is necessary for a theory. Calculating .
Cold rollingis a rolling operation carried out at room temperature. Cold rolling is commonly conducted after hot rolling when good surface quality and low thickness tolerance are needed. Cold rolling causes material strengthening. Types of Rolling 12 Some of the steel products made in a rolling mill. Rolled Products Made of Steel
Mechanics of Cold Rolling of Thin Strip 443 where yiw is the vertical deflection of the work roll at element i, gijw (, ) is the influence function for the work roll deflection due to the combined bending and shear forces generated by rolling load, giwf is the influence function for the work roll deflection due to the force generated by the roll bending mechanism, k represents the minimum element

Rolling mill for cold rolling metal sheet like this piece of brass sheet. Work rolls; Backup rolls are intended to provide rigid support required by the working rolls to prevent bending under the rolling load; Rolling balance system to ensure that the upper work and back up rolls are maintained in proper position relative to lower rolls ...
Aug 11, 2016· This is to extremes, but to understand what metallurgical changes occur during work hardening of the material, you can ultimately think of curving/forming steel like the cold rolling process. Thicker material is passed through rollers that work the material with high pressure forces, much like a rolling pin in the kitchen.
The rolling process is shown in Fig. : Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
