Abstract
An anode steel stud protection coating is formed by mixing main materials with auxiliary materials, wherein the main materials comprise 40-70wt% of bauxite, and quartz sand; and the auxiliary materials comprise a high temperature bonding agent having a weight accounting for 1-20% of the weight of the main materials, cellulose having a weight accounting for 2-10% of the weight of the main materials, and an antifoaming agent having a weight accounting for 0.1-5% of the weight of the main materials. The main materials comprising bauxite and quartz sand are hardened in high temperature environment with the aid of the high temperature bonding agent and cellulose in order to form a protection layer separating an anode steel stud from an electrolyte, alumina and other gaseous substances, so the electrochemical corrosion is effectively delayed, thereby the service life of the anode steel stud is prolonged.
Description
Technical field
The present invention relates to the anode steel jaw that use in Aluminum Electrolysis Production field, specifically a kind of anode steel jaw protective cover.
Background technology
In the time of electrolytic aluminum, carbon anode used need to use anode steel jaw that anode block is put in electrolyzer aluminum oxide is carried out to electrolysis.Because anode steel jaw is all generally to adopt cast iron casting to form, in the high temperature particular surroundings of electrolyzer, can be corroded gradually, cause its conductivity and intensity all can reduce, so not only reduce the work-ing life of anode steel jaw, and additionally increased the casting expense of anode steel jaw, cause the rising of production cost.
Summary of the invention
Thereby for being corroded in electrolyzer, solution prior art Anodic steel pawl cause its electroconductibility variation, strength decreased to affect the problem in work-ing life; the invention provides a kind of anode steel jaw protective cover; by at this protective cover of anode steel jaw external coating; thereby the particular surroundings in anode steel jaw and electrolyzer is carried out to isolation to a certain degree; the erosion process that has greatly delayed anode steel jaw, has extended work-ing life.The present invention solves the problems of the technologies described above the technical scheme of employing to be: a kind of anode steel jaw protective cover, mixed by major ingredient and auxiliary material, and wherein, major ingredient is made up of bauxitic clay and quartz sand, and the weight of bauxitic clay accounts for the 40-70% of major ingredient gross weight; Described auxiliary material comprises high temperature adhesive, the Mierocrystalline cellulose of major ingredient weight 2-10% and the defoamer of major ingredient weight 0.1-5% of major ingredient weight 1-20%.
In described auxiliary material, also contain the flower bulb alkali of major ingredient weight 1-20% and the sanitas of major ingredient weight 0.1-5%.
In described major ingredient, also contain the red mud of 5-10% and the aquamaine stone flour of 3-5%.
In described auxiliary material, also contain the Graphite Powder 99 of major ingredient weight 0.5-1%.
The preparation method of above-mentioned protective cover is: first weigh as requested the each composition in each composition and auxiliary material in major ingredient and then mix; be ground to again fineness and be no more than 100 orders; in use; add wherein a certain amount of water and stir after be painted on anode steel jaw; after brushing 2-3 time, dry in the cool, and then repeat above-mentioned brushing, dry operation and can complete the brushing of antianode steel pawl for one to twice.
In the present invention; silicon oxide in aluminum oxide and quartz sand in bauxitic clay forms the structure of similar sial spinel under hot conditions; and auxiliary material is its bonding rear formation protective layer, Mierocrystalline cellulose at high temperature dewaters after coking and is filled in wherein to prevent that corrosive gas and anode steel jaw Surface Contact from causing the effect such as galvanic corrosion or erosion.
In the present invention, by adding red mud and aquamaine stone flour, under aluminum oxide in micro-ferric oxide and the bauxitic clay containing in red mud, the silicon oxide high temperature in quartz sand, form the mullite crystal of more stable and fine and close pin, column and be similar to the vitreous state of spinel structure, and aquamaine stone flour is for filling space and compensating the volume disappearance of auxiliary material, and forms packing layer and further play isolation action.
Beneficial effect: in the present invention; the major ingredient such as bauxitic clay, quartz sand is under the auxiliary material such as high temperature adhesive and Mierocrystalline cellulose auxiliary; can in hot environment, harden; thereby forming protective layer keeps apart anode steel jaw and ionogen, aluminum oxide and other gaseous substance; effectively delay the generation of galvanic corrosion, thereby extended the work-ing life of anode steel jaw.
