Dynamic Research of the Split-Pillar Rotation Process for Electroslag Remelting Furnace

Electroslag Remelting (ESR) technology is a main method of special metallurgy; and split pillar is one of the most important mechanical units of ESR. The split pillar works not only as the mother body of ESR cross arm, but also as the rotation driving device of the cross arm. Since the tremendous mass of the cross arm and electrodes, serious inertia torque generates when the split pillar rotates, which leads to motion instability and problems of angle location and even safety threatens. In this paper, based on virtual machine technology, dynamic research of the rotation process of the electroslag-remelting-furnace split pillar was proceeded; influences of driving torque applied on the split pillar was researched, as the driving torque being constant, anti-step and with brake torque. 3D solid model of the split pillar and clamping device were established; main technical parameters were accomplished; and simulation research of the dynamic process was proceeded. It was found that, appropriate brake torque was important to better motion stability of the split pillar. The best brake torque was acquired, and the action time of the brake torque was obtained.
