1962-09-01 This paper presents a completely new approach to the mechanics of the Sendzimir hot planetary rolling mill. Previous work on this subject, by R. Tovini, included determinations for the distribution of the advance of the strip, the draft, the rolling load, the torque and the horizontal backthrust for the whole range of positions which the planetary rolls made, whilst contacting

Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90% of the critical speed. Six lifter bars of rectangular cross-section were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4. As can be seen from the ...

The roll force in flat rolling can be estimated from the formula 5.9 (For a frictionless situation; however, an estimate of the actual roll force, including friction, may be made by increasing this calculated force by about 20%). Where = average flow stress from Eq.

Rolling mill computer systems calculate setpoints for rolling using extremely complex mathematical models and send signals to engage the descale sprays and to bring the mill roll stands to speed and set the roll gaps. The rolling mill has six stands, numbered F1 F6 from south to north. Before rolling, the slabs are 55mm or 65mm thick.

We have Hot Strip Mill Horsepower Calculation Formula In Indonesia,Power in hp 513 where f is in pounds and l is in feet example a 300mmwide strip 25mm thick is fed through a rolling mill with two powered rolls each of radius 250 mm the work thickness is to be reduced to 22 mm in one pass at a roll speed of 50 revmin the work material has a flow curve

The distance ‘a’ is called the lever arm of P T (Fig. 7.13) and is expressed as a fraction of contact length L. The value of λ has been calculated by Sim by calculating torque by Eqn. (7.71b) for a large range of rolling conditions. For hot rolling λ varies between 0.49 to 0.45. Lower values are for higher reductions.

2014-06-18 Calculations of rolling power needed and loads on mechanical equipment. The calculations of load, torque and power is done based on Sims formula from billet/bloom to finishing dimension as a function of geometry, steel grade, temperature and tension. The calculation of temperature is a function of power, dimension and heat transfer co efficient. Determination of pass
