Abstract
The utility model belongs to the technical field for prebaking an anode for aluminum electrolysis, and particularly relates to a structure of an anode steel claw. After the steel claw is circularly used for a long time, the diameter of the part where the steel claw is connected with the phosphorus pig iron is reduced to form a structure which is large in the upper and small in the lower, so that the bonding force between the steel claw and a carbon block is reduced, the anode is easily stripped, and the stable and safe running of an electrolytic cell is endangered. In order to prevent the anode carbon block from being stripped off and keep the even distribution of the electric current, the utility model provides the anode steel claw with three-dimensional vein on the head of the claw. The anode steel claw enhances the frictional force and the support force between the head of the claw and the anode, thereby being capable of realizing the safe production.
Description
Technical field
The utility model belongs to used for aluminium electrolysis prebaked anode technical field, relates in particular to a kind of structure of anode steel jaw.
Background technology
Anode steel jaw is important conduction and the interconnecting piece of electrolytic aluminum industry, and the branch of three, four, six, eight pawls is arranged, and aluminium guide bar and steel pawl, anode block together constitute the anode group, wherein are cast with the phosphorus pig iron between anode anode steel jaw and the anode block.Anode steel jaw is that the cast steel that comprises multiple alloying element is made, and units such as sulphur, phosphorus are have strict requirement, S≤0.03% wherein, and P≤0.035% will have excellent conducting performance simultaneously.Smooth surface, internal level are knitted tightly, defectives such as no sand holes, slag inclusion, crackle, pore, shrinkage porosite.It is vertical that each steel pawl of anode requires to keep, and size is consistent, and parallel alternate, spacing is identical, and it is stressed identical to help all even steel pawl of distribution of current like this.After the steel pawl recycles for a long time, can cause steel pawl and phosphorus pig iron contact site diameter to diminish, form up big and down small configuration, cause the bonding force between steel pawl and the carbon piece to diminish, be easy to generate and take off utmost point phenomenon, the stability and safety operation of harm electrolyzer.For addressing this problem, the patent No. a solution that has been the CN200810140709 patent disclosure, still, the weak point of this scheme is: at first, inhomogeneous according to steel pawl distribution of current in electrolytic process that this scheme is made; Secondly, the steel pawl of making according to this scheme recycles in the process at the steel pawl, is unfavorable for the pressure-off of phosphorus pig iron ring, does not satisfy the requirement of composing room's mechanized continuous productive process.
The utility model content
For preventing that anode block from coming off and holding current is evenly distributed, the utility model provides the anode steel jaw that has three-dimensional line on a kind of pawl head.
The technical solution of the utility model comprises:
On the pawl head of steel pawl the spatial line is arranged;
Preferably, also comprise: the line on the pawl head is a burr, or dimpled grain;
Preferably, also comprise: the line on the pawl head comprises line segment type line, broken-line type line, shaped form line;
Preferably, also comprise: the line on the pawl head comprises ring-like line, round line, ellipse line, polygonal line;
Preferably, also comprise: have at least on the pawl head line is arranged;
Preferably, also comprise: have a striped on the pawl head at least.
The novel beneficial effect of this use is: the three-dimensional line on the pawl head, comprise dimpled grain and burr, can increase the frictional force between pawl head and the anode, line segment line, broken line line, wave strain line, curved grain, annular line, circular line, oval line, Polygons line, can increase frictional force and anchorage force between steel pawl and the anode, improve security.Compare with the pawl head that does not have three-dimensional line, as long as have on the pawl head striped is arranged, just can increase the frictional force between pawl head and the anode, the quantity of three-dimensional line is many more, and the frictional force between pawl head and the anode is just big more, and security is just good more.
