Rolling Mill Power Calculation

POWER IN ROLLING 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.

During manufacturing of heavy strips and plates from difficult-to-form steel grades on sheet and wide-strip rolling mills there is a problem of exact calculation of power parameters of rolling.

– Calculate rolling power. Prof. Ramesh Singh, Notes by Dr. Singh/ Dr. Colton 13 Flat Rolling Analysis • Consider rolling of a flat plate in a 2-high rolling mill

Power – It is applied to a rolling mill by applying a torque to the rolls and by means of strip tension. The power is spent principally in four ways (i) the energy needed to deform the metal (ii) the energy needed to overcome the frictional force (iii) the power lost in the pinions and power transmission system and (iv) Electrical losses in the various motors and generators

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed ...

Therefore, the calculation of the force analysis and driving power of the plate rolling machine is very important to the design of the roll bending machine. In this post, the calculation of the force capabilities of symmetrical three-roll bending machine is one of the methods, the other types of plate rolling machine can take it for reference.

Power – It is applied to a rolling mill by applying a torque to the rolls and by means of strip tension. The power is spent principally in four ways (i) the energy needed to deform the metal (ii) the energy needed to overcome the frictional force (iii) the power lost in the pinions and power transmission system and (iv) Electrical losses in the various motors and generators

after rolling. In practical the volume might decrease a little bit due to close-up of pores. 5) The velocity of the rolls is assumed to be constant. 6) The metal only extends in the rolling direction and no extension in the width of the material. 7) The cross sectional area normal to the rolling direction is not distorted. Assumptions ho hf vo ...

In the re-rolling mills, normally the 3-phase electric induction motor of high horse power is used due to the fact that the flywheel requires high torque to be driven initially. Once the flywheel stores sufficient torque which is required at the start up, the flywheel then …

Methodology for Calculation of Rolling Load and Forces Acting On Herringbone Gear Using Hot Rolling Theory

Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. ... of other problems in a mill such as a power cut, mechanical problems of transportation or in the water cooling system.

mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential ...
