the lubrication of cold rolling mills should be done well. Although the lubrication work is simple which is much higher for calenders (200 to 500) than for the roll-mills (30 to 60).36 According to IEA (2007) ranges from 1 to 2 but is usually around 1.2. The higher friction ratio leads to a higher heat generation in the processed material. Friction,

Energy Efficiency Drives for Rolling Mills. High efficiency motors can save approximately 1-2% of the electricity consumption. Assuming an electricity demand of 220 kWh/t-hot rolled steel,

The main difference between the roll-mills and the calenders is the ratio between the roll radius and the minimum gap separation between the rolls where the reduction is achieved by the inter-stand tension(s) and the compressive force between the work rolls.. For mills rolling thinner strip,

and the sizes of the rolls influence the cooling of the material mass and the intensity of its treatment.Dispersive mixing efficiency was analyzed in terms of the shear stresses generated and the elongational flow characteristics. The latter were quantified using a frame invariant flow strength parameter. We found that the converging region rather than the nip region provides better mixing flow characteristics.Best practices for safe and efficient three roll milling Technology Brief The three roll mill remains to be one of the best methods for preparing very fine particle dispersions.
