    electric force sensor technology (Fig. 7). These force sensors are very small yet can handle high loads at extremely low levels of elastic deflection. The action of mechanical pressure loads on the piezo quartz sensor produces a charge which is converted into a force-proportional voltage by the so-called charge amplifier.A comparison of friction coefficients in cold rolling,Aug 01, 1998· A rolling mill presents an excellent opportunity to verify if a friction force sensor is working properly. The friction force sensor measures forces correctly if the following conditions are met: F n,when integrated over whole the arc of contact, must be equal to the externally measured RSF.

    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.Rolling Mills Selection Guide Engineering360,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.

Drivers of rolling system are Roll Diameter an overview ScienceDirect Topics,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.
