Abstract
A kind of anode steel claw is coated with brush material, major ingredient and adjuvant mix, and wherein, major ingredient is made up of bauxite and quartz sand, and the weight of bauxite accounts for the 40 70% of major ingredient gross weight；Described adjuvant includes the high temperature adhesive of major ingredient weight 1 20%, the cellulose of major ingredient weight 2 10% and the bone meal of major ingredient weight 0.1 5%.In the present invention; the major ingredient such as bauxite, quartz sand is under the auxiliary of the adjuvant such as high temperature adhesive and cellulose; can harden in hot environment; thus form protective layer and anode steel claw is kept apart with electrolyte, aluminium oxide and other gaseous material; effectively delay the generation of electrochemical corrosion, thus extend the service life of anode steel claw.
Description
Technical field
The present invention relates to the anode steel claw that Aluminum Electrolysis Production field is used, a kind of anode steel claw brushing
Material.
Background technology
When electrolytic aluminium, used carbon anode needs to use anode steel claw to be put into by anode block in electrolysis bath oxygen
Change aluminum to be electrolysed.Cast iron casting is used to form owing to anode steel claw is typically all, in the high temperature special environment of electrolysis bath, meeting
Gradually corroded, cause its electric conductivity and intensity all can reduce, so not only reduced the service life of anode steel claw, and
Also adds additional the casting expense of anode steel claw, result in the rising of production cost.
Summary of the invention
For solve prior art Anodic steel pawl be corroded in a cell cause its electric conductivity be deteriorated, intensity reduce thus
The problem affecting service life, the invention provides a kind of anode steel claw and is coated with brush material, by this guarantor of anode steel claw external coating
Protect coating, thus anode steel claw is carried out a certain degree of isolation with the special environment in electrolysis bath, significantly delay anode steel
The erosion process of pawl, extends service life.The present invention solves that the technical scheme that above-mentioned technical problem uses is: a kind of anode
Steel pawl is coated with brush material, major ingredient and adjuvant mix, and wherein, major ingredient is made up of bauxite and quartz sand, and the weight of bauxite
Account for the 40-70% of major ingredient gross weight；Described adjuvant includes the high temperature adhesive of major ingredient weight 1-20%, the fiber of major ingredient weight 2-10%
Element and the bone meal of major ingredient weight 0.1-5%.
Possibly together with sodium silicate, the preservative of major ingredient weight 0.1-5% and the major ingredient weight of major ingredient weight 1-20% in described adjuvant
The defoamer of amount 0.1-3%.
Possibly together with red mud and the aquamaine stone powder of 3-5% of 5-10% in described major ingredient.
Possibly together with the graphite powder of major ingredient weight 0.5-1% in described adjuvant.
The preparation method of above-mentioned protective coating is: each composition first weighed the most as requested in major ingredient in each composition and adjuvant is right
Rear mix homogeneously, then it is ground to fineness less than 100 mesh, in use, it is added thereto to a certain amount of water and stirs
It is painted on anode steel claw after mixing uniformly, dries in the cool after brushing 2-3 time, then repeat above-mentioned brushing, dry operation
One to twice can complete the brushing to anode steel claw.
Bone meal used in the present invention is that animal skeleton pulverizing forms, and it at high temperature plays and makes adjuvant more preferable with major ingredient
The effect merged, makes the materials such as cellulose in adjuvant can be with uniformly penetrating in the structure that major ingredient is at high temperature formed, meanwhile,
Give the high-temperature shrinkage ability that protective layer is certain, prevent it dry and cracked.
In the present invention, the aluminium oxide in bauxite forms similar sial point under the high temperature conditions with the silicon oxide in quartz sand
The structure of spar, and adjuvant by its bonding after form protective layer, cellulose be filled in wherein after being at high temperature dehydrated coking in case
Only corrosive gas contacts with anode steel claw surface and causes electrochemical corrosion or erosion etc. to act on.
In the present invention, by adding red mud and aquamaine stone powder, the micro-oxidation ferrum contained in red mud and the oxygen in bauxite
Change and form more stable and fine and close pin, the mullite crystal of column under the silicon oxide high temperature in aluminum, quartz sand and be similar to
The glassy state of spinel structure, and aquamaine stone powder is for filling space and compensating the volume disappearance of adjuvant, and form packed layer
Further play insulating effect.
Beneficial effect: in the present invention, the major ingredient such as bauxite, quartz sand is in the auxiliary of the adjuvant such as high temperature adhesive and cellulose
Under, can harden in hot environment, thus form protective layer by anode steel claw and electrolyte, aluminium oxide and other gaseous state
Material is kept apart, and has effectively delayed the generation of electrochemical corrosion, thus has extended the service life of anode steel claw.
