The principle is that the neutral saline solution is used as the electrolyte, and the strip steel enters the descaling device composed of several electrolytic cells after mechanical shelling. Using the principle of electrolysis, under the accurate control of the mathematical model of electrode and strip steel, the oxide layer on the surface of strip steel is separated from the matrix through the interaction of electrode, so as to achieve the purpose of descaling the surface of strip steel. 

In the process of electrolytic cleaning, iron oxide solid substances will gradually accumulate. When the solid iron oxide reaches a certain concentration, the electrolyte will separate the iron oxide through the pressure filtration system to form iron oxide black. After drying, iron oxide red ultrafine powder can be produced. 2.5kg iron oxide red can be produced for each ton of steel coil. The price of high-quality iron oxide red is very cheap.
