摘　　要：利用电磁感应涡流加热原理,对8MN压力机机架的4个螺栓进行预紧。通过对电磁感应涡流加热的计算,确定了加热电源的最低功率、感应器线圈的最小线径以及感应线圈在螺栓上缠绕的匝数。为准确选用电源功率提供了理论依据,有效解决了压力机螺栓预紧的关键技术问题。Used the principle of electromagnetic induction eddy current heating to preload the 4 screw bolts of 8MN press rack. Through the calculation of electromagnetic induction and eddy current heating, determined the minimum power of the heating pow er, the minimum diameter of the sensor coil and number of turns of induction coil wound on the bolt. The paper provided a theoreti cal basis for the accurate selection of the electrical power, and effectively solved key presses screw bolt preload.
