The speed of the rolling mill is set at 10 rpm, giving a roll surface velocity of mm/s. It was found necessary to use guides for the bars, both at entry and exit, in order to minimize sideways bending. The parameters monitored during the experiments include the temperature, roll force and torque.
The second DCS800 drive was installed on the 50horsepower leadin paper roll which is used to transport the paper to the slitter section. The third and fourth drives were installed on the 250HP front and rear drums components that are responsible for providing machine speed reference and profiling torque to the rewound roll ...
That is why it is reasonable to apply onedimensional model, based on the known dependences of rolling pressure and mill torque calculation. Currently, several dependences are known for determining the mill torque in stands with multiroll grooves [6,23,24,25,26]. Some of them are obtained for specific cases, others are more general.
The proposed onestand hot tandem rolling mill was constructed using 60 mm diameter work rolls, 150 mm diameter backup rolls, 120 mm diameter spur gears, a 3 hp electric motor, and a 50 mm ...
The roll force components F, and F, and the roll torque estimates GT and GH were determined in each case together with the neutral angle O . The roll torque G was also calculated from energy considerations using Eqn (41). Calculations were made with the arc of contact divided into 200, 500, 1500 equal divisions.

This set of Mechanical Metallurgy Multiple Choice Questions Answers (MCQs) focuses on "Metals Torque and Power". 1. The neutral point in the rolling machine is defined as the point where ________. a) the material enters the machine. b) the material exits the machine. c) the roll speed is equal to the material flow speed.
The 2D mill, with its driving shaft connected with a load beam measuring the torque when the mill is running, has its speed adjusted from 0% up to 200% of critical speed. A digital camera is used to take pictures of the load in the 2D mill with a digital stroboscope as the light source. 3. Construction and validation of PDP
