Abstract: In order to meet the accuracy requirement of rolling pressure measurement of rolling mill, a sensor structure for compensating rolling pressure measurement was proposed. The new structure sensor is helpful to improve the accuracy of the general rolling pressure sensor, and make appropriate amendments and compensation to avoid the influence of friction between the bearing seat and the frame on the value obtained by the sensor, and improve the working performance of the sensor. The mechanical model of the measuring device was established, and the force ansysis of the testing characteristics of the device in operation was carried out. The structural design, theoretical analysis and finite element verification of the device were carried out based on the research of compensation and modification device design. The factors causing errors in conventional rolling pressure measurement due to neglecting the friction between the bearing seat and the stand on the sensor acquisition value were studied. A solution had been proposed to correct and compensate the measured values of the traditional rolling pressure sensor by adding a pull rod sensor.
