The function of the pressure ring electrode system is to press the copper tile to hold the electrode, so that the current through the copper tile evenly through the electrode into the furnace.

    The pressure ring is composed of two half-circle rings, the internal water circuit is very complex, the cooling water first into the lower chamber, then along the outer water-cooled chamber from the bottom to the top of the cycle, and then into the inner circle cycle, and finally discharged. The outer water-cooled chamber is very narrow and the inner ring is wider. The cooling effect of the pressure ring near the flame part is very good, which ensures the long service life of the pressure ring.

    The main structural features of the bellows pressure ring gripper are: the copper tile is topped with a telescopic box composed of bellows. It consists of water-cooled protective sleeve, water-cooled pressure ring, water-cooled pressure bellows and hydraulic medium. In the clamping ring bellows one-to-one top tightening forging copper tile, this is the pressure ring than cone ring superior place, can ensure that each piece of copper tile on the electrode holding force balance, easy to adjust the copper tile on the electrode of the pressure, so the use of such a pressure ring can prolong the use of copper tile cycle.
