It is a good practice to use the principle of the three-stand mill modeling developed at investigation of rolling mills with different number of the continuous stands. 2. The actual rolling mill has been quantitatively evaluated with regard to the force interaction of the electric drives at fluc-tuations of the rolling conditions. 3.

Get QuoteJun 19, 2017 The capacities of long product rolling mills can vary in the range of 300,000 tons per year to 800,000 tons per year. The rebars mills can be designed with capacities of over 1 million tons. Modern long products mills are usually installed at higher levels around 6 m from ground level.
Get Quote2. Rolling Mill classification Rolling mill is used to reduce successively the thickness of the metal strip as per the requirement. Hot rolling mills are used for mass thickness reduction at high temperatures, whereas the cold rolling mills are used as secondary rolling operations to attain more precise dimensional and mechanical properties.
Get QuoteAbstract. Equations are derived for the normal roll pressure, specific roll load and torque in hot rolling mills, using the condition for plastic deformation in rolling derived by Orowan, together with von K rm ns equation of equilibrium. Although applying strictly to the rolling of ideal plastic-rigid materials, these equations may be ...

Get QuoteThe mill modulus is 500-1,000 tonmm for plate rolling mills and 400-600 tonmm for cold rolling mills. The larger the diameter of the back-up rolls, the higher the mill modulus. A rolling force of the order of 1,000 tons is generated during rolling, so that mill deformation of more than 1mm occurs.
Get QuoteSep 30, 2020 In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...

Get QuoteIn terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. Roll stands, holding pairs of rolls, are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel I-beams ...
Get QuoteThe elastic deformation of rolling mill elements during the rolling process is important. By knowing the displacement of rolls, the optimum gap between the work rolls can be calculated. In present research, a vibration model with two degrees of freedom is proposed for a cold sheet rolling mill and the stiffness parameters of different mill elements are calculated.
