Electrode device of electrochemical cleaning salt-bath furnace

Abstract

The invention relates to an electrode device of an electrochemical cleaning salt-bath furnace. The device comprises a square cylinder enclosed by four electrically-conducting square side plates and a square bottom plate, wherein every two adjacent side plates are connected through a plurality of first electrically-conducting blocks that are vertically arranged and spaced with each other, so as to form a gap between every two adjacent side plates, and each side plate is connected with the bottom plate through a plurality of second electrically-conducting blocks that are vertically arranged and spaced with each other, so as to form a gap between each side plate and the bottom plate. A 45-degree chamfer is formed at each corner of the bottom plate and each of the side plates, and the bottom plate and each of the side plates are all steel plates of thickness 12-20 mm. The distance between the two adjacent first electrically-conducting blocks is 200-300 mm, the distance between the two adjacent second electrically-conducting blocks is 200-300 mm, and the first electrically-conducting blocks and the second electrically-conducting blocks are all made of 18*18 mm square steel. The electrode device provided by the invention has the advantages of uniform charge distribution, slow corrosion and long service life, so that the electrochemical cleaning salt-bath furnace has good cleaning effect and high cleaning efficiency.

Description

technical field [0001] The invention relates to an electrode device, in particular to an electrode device for electrochemically cleaning a salt bath furnace in the foundry industry. Background technique [0002] Electrochemical cleaning is called "Kolene" treatment in foreign countries, and it is used to clean hydraulic parts, gas turbine shells, crankcases, investment casting cast iron and steel castings with complex inner cavity structure and high inner surface cleanliness requirements. Can be used for surface treatment of steel. After the workpiece is electrochemically cleaned, in addition to making the inner cavity free of sand and scale, the service life of the metal cutting tool can be increased by about three times. At the same time, the surface corrosion resistance of the workpiece can also be improved to eliminate internal stress. The key equipment of electrochemical cleaning is called salt bath furnace, and its working principle is as follows: put the preheated wo...

AI Technical Summary

Problems solved by technology

At present, the electrochemical cleaning salt bath furnace is usually equipped with a special electrode device in the tank body. The structure of the electrode device is a total of five steel plates, front, rear, left, right and bottom, which are welded continuously. The electrode device has uneven charge distribution, electrode The defects of fast corrosion and short service life of electrodes make the cleaning effect of electrochemical cleaning salt bath furnace poor
