压力环
矿热炉压力环主要采用油缸式压力环、波纹管式压力环和蝶璜式压力环三大类。其中波纹管式压力环又有内置式和外置式两种。其优点是，可实现一对一的径向顶紧铜瓦，而不受电极倾斜和表面质量的影响，使铜瓦与电极之间压力均匀，不宜产生偏流，提高铜瓦的使用寿命，便于实现PLC自动控制带电压放。更有效的维护和防止电极事故的发生。
Ore arc furnace pressure ring mainly uses cylinder pressure ring, bellows-type pressure ring and papilionaceous spring pressure ring the three categories. Wherein the bellow pressure ring has two categories --built-in type and external type. The advantage is, you can achieve a straight radial tight copper tile , without being affected by the electrode inclination and surface quality, so that the pressure between the electrode and the copper tile is uniform., not producing bias and improve the life of copper-watt, easily realizing PLC automatic voltage discharge and more effective maintenance and preventing electrode accidents.
