摘要： The electrodes (29) have jet openings (26) which jet the electrolyte (31) to the steel strip (1), that is to say, the electrode is integrated with the nozzle which jets an electrolyte.
By jetting the electrolyte to the steel strip in the air and applying a voltage to the electrode, the scale on the surface of the steel strip is removed. By jetting the electrolyte in the air, there is reduction in the size of an electrolyte tank storing the electrolyte, because the required quantity of an electrolyte decreases. Therefore, the descaling apparatus is miniaturized. Short-circuit electric current through electrolyte between electrodes decreases, and thereby the electric power efficiency improves. By individually adjusting the jet pressure of the electrolyte jets, the waving and the flexure of the steel strip is prevented, and we can arrange the electrodes close to the steel strip to reduce electric power. Providing many electrodes is accomplished because of the reduction in short circuit current and the improves the speed of the descaling because the electric current to the steel strip increases.摘要翻译： 电极（29）具有喷射口（26），喷射电解液（31），以钢带（1）确实是说，电极被集成在喷嘴电解质的哪射流。 通过喷射电解液在空气中的钢带与将电压施加到所述电极，所述钢带表面的氧化皮被除去。 通过在空气喷射电解质，有减少在电解液罐存放电解液的大小，因为电解质的所需量减少。 因此，去氧化皮装置被小型化。 通过电极之间的电解质的短路电流减小，从而将电力效率提高。 通过单独地调节所述电解质射流的射流压力，挥动与钢带的挠曲被阻止，并且我们可以安排接近钢带电极以降低电力。 提供了许多电极是完成，因为在短路减少的电流和提高除垢的速度，因为电流在钢带增加。
