The anode steel claw material is characterized by comprising the following components in percentage by weight: 0.05 to 0.12 percent of carbon, 0.25 to 0.5 percent of manganese, 0.05 to 0.37 percent of silicon, 0 to 0.1 percent of copper, less than 0.05 percent of phosphor, less than 0.05 percent of sulfur, less than 0.1 percent of chrome, less than 0.05 percent of nickel (Ni) and the balance of iron. In the anode steel claw material for the aluminum electrolysis, by re-designing the alloying element content of the steel claw material and particularly reducing the elements, such as carbon, manganese and the like, the resistivity of the steel claw and anode steel claw pressure drop are reduced and the production cost is effectively reduced.
Description
Technical field
A kind of anode steel claw material for aluminum electrolysis relates to a kind of anode steel claw material for aluminum electrolysis that can reduce the anode steel jaw pressure drop.
Background technology
In the production process of electrolysis of aluminum, anode is described as " electrolytic heart ", and as one of vitals of anode assembling, and the pressure drop of anode steel jaw is determining the power consumption of ton aluminium to a certain extent.
The material of early stage anode steel jaw mainly is ZG230-450, and it is all higher that this material contains the kind and the quantity of alloying element, thereby resistivity is bigger, and the pressure drop of steel pawl is also higher; Recently, Kweiyang magnalium designing institute has designed the new anode steel jaw (patent No.: 200510200136.8) with ZG200-400 for material, new material is compared with original material, steel interalloy composition decreases, the conductive capability of material slightly increases, but its steel pawl pressure drop still maintains in the higher numerical range.Pingguo, Guangxi Aluminum has been invented a kind of Energy-saving model anodic steel claw, and (patent No.: 200310117269.X), the crossbeam of this steel pawl is a skeleton with aluminium, and the surface has wrapped Plate Steel, links together by welding and pawl.The application of this steel pawl has reduced pressure drop in a short time to a certain extent, but along with the increase of life cycle, because the difference of the steel and the aluminothermy coefficient of expansion, makes to produce the gap between the contact surface of steel and aluminium, has caused pressure drop not fall counter increasing.
Summary of the invention
The object of the invention is exactly the deficiency that exists at above-mentioned prior art, and the electroconductibility that can effectively improve anode steel jaw is provided, and reduces the pressure drop of steel pawl, reaches the purpose electrolysis anode steel claw material that saves production cost.
The objective of the invention is to be achieved through the following technical solutions.
A kind of electrolysis anode steel claw material is characterized in that the weight percent of this material consists of: carbon 0.05%-0.12%, manganese 0.25%-0.5%, silicon 0.05%-0.37%, copper 0-0.1%, phosphorus are less than 0.05%, and sulphur is less than 0.05%, chromium is less than 0.1%, and Ni is less than 0.05%, and all the other are iron.
A kind of electrolysis anode steel claw material of the present invention, optimize, designed the composition and the alloying element content of steel pawl material, especially elements such as carbon, chromium have been reduced, by reducing carbon, the manganese content in the steel claw material, and interpolation copper increases conductivity, reduce the resistivity of steel pawl, effectively reduced the production cost of enterprise.
