Abstract

The invention relates to an acid pickling electrode plate comprising an acid pickling plate body and an electrode plate protective structure. The electrode plate protective structure comprises four corner wrapping protective plates. Each corner wrapping protective plate comprises a first corner wrapping edge and a second corner wrapping edge which are perpendicularly connected. The four corner wrapping protective plates cover four corner portions, parallel to the width direction of band steel, of the electrode plate body respectively. The invention further provides an acid pickling electrode plate system comprising an upper electrode plate subsystem and a lower electrode plate subsystem. All upper electrode plates and all lower electrode plates are the acid pickling electrode plates. By the adoption of the acid pickling electrode plate and the acid pickling plate system, the situation that in the production process, due to an irregular shape of the band steel, the band steel collides with the surface of the electrode plate, a protective film on the surface of the electrode plate is damaged, and then corrosion is accelerated is avoided; besides, the phenomenon that formed acid mud is accumulated at the corner of the electrode plate and accelerates corrosion of the electrode plate can be avoided; in this way, the service life of the electrode plate can be effectively prolonged, and production cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of cold-rolled stainless steel production, and in particular relates to a pickling electrode plate and a pickling electrode plate system that can delay electrode plate corrosion. Background technique [0002] At present, when pickling cold-rolled stainless steel strip, electrolytic pickling + mixed acid pickling process is generally adopted, and the electrolytic pickling process includes neutral salt electrolytic pickling and nitric acid electrolytic pickling. In the neutral salt electrolytic pickling process, when the shape of the strip steel plate is not good, the strip steel will collide with the electrode plate, damage the electrode plate, and shorten the service life of the electrode plate. In addition, during the neutral salt electrolytic pickling process, some metal deposits will be produced, and the oxide scale on the surface of the strip will also peel off. When the peeled oxide scale and metal depo...
