Embodiment Construction

[0033] The specific implementation of the anode plate of the stainless steel cold-rolled pickling line and its manufacturing method will be described in detail below in conjunction with the examples and accompanying drawings, but the specific implementation of the anode plate of the stainless steel cold-rolling pickling line and its manufacturing method are not limited in the following examples.

[0034] Example of anode plate

[0035] figure 1 The anode plate of the described stainless steel cold rolling pickling line has a core plate 6 . The longitudinal section of the core plate 6 is in the shape of a handle. The core plate 6 includes two side plates 3 and a bottom plate 5. There is an outwardly bent mounting plate 1 on each of the upper sides of the mounting plate 1, and there is an electrical connection through hole 2 on the mounting plate 1. The core plate 6 is 4500mm long, 580mm high, and the cross-sectional specification is 200mm×24mm. The main part of the core plate...

Abstract

The present invention relates to an anode plate of a stainless-steel cold-rolling pickling line and a manufacture method thereof. The anode plate is characterized in that one part of a core plate soaking in acid when the core plate is in acid cleaning is coated by a corrosion-resistant alloy layer which comprises 5-12% of Sb, 0.2-1.0% of Cu, 0.2-1.0% of Bi, 0.1-0.5% of Ce and the balance of Pb and unavoidable impurities. The manufacture method comprises the following steps of: (1) preparing an alloy layer soldering sheet: firstly, preparing a Cu-Sb interalloy: a, using CuSb50 as a Cu-Sb alloy; b, casting the Cu-Sb alloy in a die into a furnace burden; secondly, smelting the alloy: a, preheating a smelting furnace; adding the Cu-Sb interalloy to smelt; b, adding Bi, Sb and Ce; c, adding the rest Pb; d, discharging from the furnace and casting; thirdly, preparing a soldering sheet: casting alloy liquid into a soldering sheet; and (2) welding the soldering sheet: a, polishing the core plate and removing gas; b, firmly clamping the core plate; and c, welding the soldering sheet and the core plate. The anode plate of the stainless-steel cold-rolling pickling line resists corrosion and has low cost.

Description

technical field [0001] The invention relates to an anode plate of a stainless steel cold rolling pickling line and a manufacturing method thereof. Background technique [0002] Neutral salt electrolytic pickling is one of the most advanced methods for descaling cold-rolled stainless steel strip today. In the process of electrolytic pickling, the cathode plate is basically free of corrosion, so its material can be made of ordinary carbon steel, while the anode plate is continuously corroded and consumed due to electrochemical action. When the thickness of the corrosion-resistant layer is less than 1-2mm, it must be replaced with a new one. Spare parts are available for production. Therefore, the choice of anode plate material has become a key link in determining the service life. At the same time, the choice of materials should also take into account manufacturability, economy and safety. In China, anode plates are usually imported with foreign complete sets of equipment. ...
