rolling mill separating force sensors

A precision rolling mill, built in 2003, with 140 mm roll diameter of the Prymetall company was used for the experiments. During the rolling of the OF-Cu bars the rolling force was measured. There were no forward and backward tensions applied on the copper bars and rolling speed was reduced to a minimum of about 0.75 m/min.

On one of the rolls, sensors measuring the force applied to the tools during the rolling process, were applied at locations marked with the number 1. Two pairs of tools were used for the model tests. The first pair of tools has only a separating collar, which forms a knife to separate the balls, while the second set of tools used has two knives ...

3.2 Line contact sensors Rolling is a process which has attracted much atten-tion in sensor development. Measuring the frictional force in the rolling direction is of interest and there has been development of a special set of 'line sensors' to measure the frictional force across the roll face. These are illustrated in Fig. 5.

Friction variation along the rolling contact interface was measured by a 'sensor roll' embedded with sensors on an experimental rolling mill. The measured results show that the friction ...

The rolls are installed in the exit section of the rolling mill. Highly sensitive and precise force sensors are integrated into the roll, distributed over the strip width. If a fly were to land on the Shapemeter roll, these sensors could measure its impact. The sensors measure the force distribution applied over the strip width, which is a ...

MILL LOAD - Roll Force, Torque, Power The Mill Load application is specifically developed for mill design/operation engineers to calculate roll separating force, rolling torque and power, etc. Typically, load calculation is needed for an existing mill when a new rolling process is applied either with higher reduction or in lower temperature or higher speed, or for a stronger material.

Roll Force load cells PFVL141. The Millmate Roll Force load cells act as integral parts of the mill stand. The rocksolid Pressductor ® load cell design in combination with the intelligent, reliable communication functions are crucial keys to true roll force measurement.

roll force and torque in the hot rolling process. As an improvement, Poliak, Shim, Kim, and Choo (1998) examined a proposed linear regression model to predict the roll force in hot plate rolling. Lee and Lee (2002) proposed a long-term learning method using neural network to improve the accuracy of rolling-force prediction in hot rolling mill ...

For each series, model, and type of machine, three diameters may be listed: work rolls, back-up rolls, and roll journal. Other parameters include maximum separation force at 1000 feet per minute (fpm), total column area, and estimated floor space. Rolling mills include both small, manually-operated bench top systems and large, powered machines.

A rolling mill is characterized by the maximum values of its roll separating force and the torque. The maximum amount of deformation (thickness reduction) which may be achieved in a single rolling pass is determined by the maximum roll separating force, maximum torque, work roll diameter, friction coefficient and mechanical strength of the ...

Mill spring or plastic distortion. The reaction to rolling load is called the roll separating force and if the rolls were not held in the mill housing they would indeed separate and reduction of metal would not be possible. The upper roll pushes the top of the housing upwards whilst the bottom roll pushes the base of the housing downwards.
