Research of on-line monitering technology with the new magnetic potentiometer

The theory and the practice can test and justify that during roasting,detecting on line heavy direct current of the positive plate of the electrobath of the Al with the magnetic potentiometer (MP),which can ensure the electrobath of the Al come through the phase of the roasting successfully.Falling back on the current curve and even coefficient,can find the positive plate of the electrobath with unbalanced current.This method can raise the quality of the roasting,shorten the time of roasting,even more can improve the quality and the efficiency of the electrolysis of the electrobath of the Al.
