Roll pass design  Definitions  LinkedIn SlideShare
Similarly when a hot bar is worked between two rolls, it spreads in the pass filling the pass and it pushes out in the direction of rolling ( forward slip )and backwards in the direction of the incoming stock (backward slip). This phenomenon is also called 'the extrusion effect'. Forward slip must be added to the bar speed to calculate roll speed for tension free rolling at high speeds in

Figure 1: Limit the range of tube sizes using common breakdown passes to 20% In addition to running strips for various diameter tubes through common breakdown passes, the tubes may also vary in material thickness. In Figures 2 & 3, the gauge variation is seen most prominently at the strip edges. Figure 2: Running lighter gauge material with heavier gauge top roll Figure 3: Running heavier

Surface and Inner Deformation during Shape Rolling of High
rollpass design will result in defect free products with correct dimension. In the work of improving the rollpass design finite element simulations are a useful tool. Using FEM can provide a picture of the deformation of the billet and risks for defects could possibly be detected. A drawback of FE is, however, that the simulations generally are quite time consuming. 1 . 2. Defects in wire

POWER IN ROLLING  idconline.com
Power is applied to the rolling mill by applying Torque to the rolls and by using roll strip tension.The total rolling load is distributed over the arc of contact. However, the total rolling load can be assumed to be concentrated at point along the arc of contact ata distance 'a' from the line of centers of the rolls. The ratio λ = [ a/Lp] = [a/√R.∆t] is used to calculate the moment

Rolling [SubsTech]
A rolling mill is characterized by the maximum values of its roll separating force and the torque. The maximum amount of deformation (thickness reduction) which may be achieved in a single rolling pass is determined by the maximum roll separating force, maximum torque, work roll diameter, friction coefficient and mechanical strength of the rolled material and its width.

Calculation of Fusion Zone Size in the Submerged
Results are presented from calculation of the dimensions of the fusion zone in the hardfacing of rollingmill rolls by a composite strip electrode. The calculation is performed on the basis of the solution of a differential equation of heat conduction that accounts for the temperature dependence of the thermophysical properties of the material comprising the rolls.

As the new rolling mill, two stands of the threeroll rolling mill were selected (Fig. 1). The major feature of the threeroll rolling mill is its ability to suppress the variations of dimension between the three grooved rolls that roll the entire circumference of a rolled stock and thereby lessen the spread as compared to a conventional twohigh rolling mill (Table 1). 2.3 Construction of the
