The tension value of Ut of hot roll strip mill. where σ is yield stress. Yield torque which strip bending deformation needed occupies a larger proportion in the total output torque. Bending torque changes according to the material properties and its size, so it is a very im portant to calculate the torque.

rolling load . Rolling force in hot rolling: Material flow in hot rolling is less homogeneous. Strain rate also affects the flow stress of the material. Further, friction conditions are rather unpredictable. Friction coefficient in hot rolling may be high – ranges from to Strain rate in hot rolling can be found out from the expression:
FEA Analysis of Stresses and Deflection Induced in Rollers of ReRolling Mills P. R. Gajbhiye1 Jitendra Vyas2 Akshay Gundewar3 Akash Nandanwar4 1,2,3,4Department of Mechanical Engineering 1,2,3,4KDKCE, Nagpur Abstract— FEM Analysis is a numerical method that can be used for the accurate solution of complex engineering problem.
horizontal roller corn harvester was designed, and the work effects between the constant speed snapping rollers and the differential speed snapping rollers were compared by using software CATIA and ADAMS, and found that the rolling speed of inner snapping roller is 500r/min, and the outer snapping roller is 460r/min are the best transmission rate.
Roll separating force during rolling actually depends on three primary factors: the mean flow stress, the projective contact area and the shape factor. Mean flow stress depends on material only (including deformation history), and the shape factor is affected by the strain state and stress state in the deformation zone.
Cluster mills have the advantage of running very light gauges under precision tolerances. As an example, a Cauffiel 18high rolling mill is used for running high carbon alloys at an accuracy of ± .00098" ( ± ) at speeds up to 1,000 FPM.

Difference between conventional (Three) roller mill and new two roller mill Fig Conventional roller mill New 2roller mill In conventional mill, · Trashplate absorbs almost 25% of hydraulic load applied on Top Roller. · Only ~75% of Hydraulic Load utilized for juice extraction. · 2025% power loss in dragging the bagasse over trashplate.
Jan 28, 2009· The rollers and the workpiece exert force on each other, and if either is absent, there is no force on either. The rollers exert force on the mill frame at their bearing points. There is no benefit to trying to make a distinction between who presses on who as it does not change what happens nor does it change the design of the rolling mill.
Due to the excellent and accurate measuring results, the RFS4 system was adopted during the trial period to replace the existing rolling force measuring system. The RFS4 rolling force measuring system is easy to add on to existing rolling mills and offers an excellent return on investment.
MANUFACTURING PROCESSES ... thickness of the entering bar therefore a friction force is ... Forming Processes Rolling3 5 A machine used for rolling metal is called rolling mill. A typical rolling mill consists of a pair of rolls driven by an electric motor transmitting a torque through a gear and
ADVERTISEMENTS: After reading this article you will learn about the design of rolling mills. A rolling mill includes one or more roller stands, a main drive motor, reducing gear, stand pinion, flywheel, and coupling gear between the units. The roll stand is the main part of the mill, where the rolling .
