Embodiment Construction
[0019] The present invention invents a new type of copper-iron composite anode material for corrosion and fouling protection of copper-nickel alloy seawater pipelines in ships. The main components are Fe (residual), 30% Cu, (1-3%) Cr, (2 ~5%) Mn, (0.5~2%) Sn, (0.4~1.8%) Al. The production method is: use a medium-frequency induction furnace, add pig iron and electrolytic manganese into the furnace at the same time, cover it with perlite, add micro-carbon ferrochrome to it after the raw materials are completely melted, and then raise the temperature to about 1600 ° C, wait for micro-carbon ferrochrome After the molten steel is completely melted, stir the molten steel evenly, remove the slag, take it out of the furnace, stand still until the temperature of the molten steel is about 1510°C to 1550°C, and cast the Fe-Mn-Cr alloy. The formed Fe-Mn-Cr alloy is used as an intermediate alloy, which is added to Cu-Sn-Al copper alloy parts for melting and casting at about 1400 °C, and a ...

The invention discloses a copper-iron alloy composite positive electrode material for electrolysis, an electrode assembly and an electrolysis device. The copper-iron alloy composite positive electrode material comprises the following components in percentage by weight: 30% of Cu, 1-3% of Cr, 2-5% of Mn, 0.5-2% of Sn, 0.4-1.8% of Al and the balance of Fe; the copper-iron alloy composite positive electrode material is cast and molded in one time after smelting, and is formed into the electrode assembly to be applied to seawater cooling pipes. The copper-iron alloy composite positive electrode material, the electrode assembly and the electrolysis device have the advantages that through the adoption of the novel copper-iron alloy composite positive electrode material, the positive electrode anticorrosion and antifouling technology and the sacrificial positive electrode protection are combined to solve the problems of serious corrosion leakage of copper and copper alloy seawater pipelines of a ship and marine organism contamination in the prior art, the required service life of copper-nickel alloy seawater pipelines of the ship is the same as the overall life, the dock repair interval is 3 to 5 years, the marine organism contamination rate is reduced to 5% or lower, and the use requirements of the copper-nickel alloy seawater pipelines are met. The electrolytic device and the electrode assembly adopting the structure is simple to use and operate, and convenient to mount and maintain, and can save space.
Description
technical field [0001] The invention relates to a copper-iron alloy composite anode material for electrolysis used for the corrosion protection of copper-nickel alloy seawater pipelines, and an electrode assembly made of the material, as well as an electrode assembly made of this electrode assembly used in seawater pipelines anti-corrosion electrolysis device. Background technique [0002] Due to the small diameter of the pipe, many accessories such as elbows, tees, and valves, the straight pipe section is short, the seawater flow rate is high, and the degree of turbulence is large, not only the corrosion damage is serious, but also the corrosion protection is very difficult. External power protection has not been successfully applied so far, and sacrificial anode protection has been widely used. However, when sacrificial anode protection is used, since the diameter of the seawater pipeline is mostly small, the current shielding is serious and the anode spacing is greatly l...
