Abstract

The invention discloses an anode steel claw protecting cover which comprises a cross beam, wherein a claw body is fixed at the lower end of the cross beam; one end of the claw body penetrates througha cylinder and extends to one end of the cylinder; a placing plate is fixed at the lower end of the claw body; a protection structure is arranged on the cylinder; mounting boxes are arranged on both sides of the upper end of the cylinder; fixing devices are arranged between the mounting boxes and the cylinder; second connecting plates are fixed between opposite side walls in the cylinder; first openings are formed in one ends of the second connecting plates; a first connecting plate is arranged between the two second connecting plates; and fourth openings are formed in two ends of the first connecting plate. The anode steel claw protecting cover disclosed by the invention has the advantages that the protecting cover is added to a steel claw to protect the steel claw from corrosion; the using period of the anode steel claw is effectively prolonged; the replacement of the steel claw is reduced; the problem that the corrosion speed of the anode steel claw is increased due to high temperature environment and the like is solved; the use is convenient; and the resources are saved.

Description

technical field [0001] The invention relates to the technical field of steel claw protection covers, in particular to an anode steel claw protection cover. Background technique [0002] The anode steel claws of the electrolytic aluminum plant are equipped with anode carbon blocks and placed in the electrolytic cell to electrolyze alumina. Under high temperature environment, the electrochemical corrosion of the anode steel claws is very fast. For example, the diameter of the steel claw legs is reduced from 170mm to 120mm, and the cross-sectional area It will be reduced by half, the resistance will be doubled, and the resistance heat loss will be further increased. Although various aluminum factories and some scientific research units have come up with many methods, the effect is not ideal: there are still steel claws under the anode steel claws that are continuously corroded. After the anode steel claws become thinner, the resistance will increase a lot, which will also lead ...
