The invention discloses an anti-corrosion impeller with an inverted long-angle arc swirl and an anti-corrosion stirring paddle with an inverted long-angle arc swirl. The technical point of the present invention is that the upper convex surface of the two sides of the arc-shaped blade is an inverted long angle, and together with the lower part of the two sides close to the right-angled side, the upper liquid entry surface and the lower opening liquid surface of the blade are formed, and the side of the upper liquid entry surface The sides are composed of two angled lines with similar lengths; the root of the convex surface of the arc-shaped blade is the part close to the stirring shaft, the middle part and the tail, that is, the cross-section of the part away from the stirring shaft is an arc surface formed by circles with different radii; the arc The cross-section of the root of the concave surface of the blade, that is, the part close to the stirring shaft, the middle part and the tail, that is, the part away from the stirring shaft is also an arc surface formed by circles with different radii. The invention provides an anti-corrosion paddle and a stirring paddle with an inverted long-angle arc swirl flow that can widen the extension force of the flow channel of the stirring paddle blade and the strong swirl force of several shapes, and has the effects of saving electricity, reducing consumption, increasing production, and has a long service life. .

The invention discloses a sintering synergistic agent comprising the following components in percentage by weight: 20-30% of active calcium oxide with the activity of more than or equal to 280 ml / 4N-HCl, 20-30% of active magnesium oxide with the activity of more than or equal to 180 ml / 4N-HCl, 20-30% of fluorite, 5-10% of diboron trioxide with the purity of more than or equal to 99% and 5-15% of copper sulfate with the purity of more than or equal to 95%, wherein the content of the active calcium oxide with the granularity of 0.074 mm is more than or equal to 70%; the content of the active magnesium oxide with the granularity of 0.074 mm is more than or equal to 60%; and the content of the fluorite with the granularity of 0.147 mm is more than or equal to 60%;. In the sintering synergistic agent disclosed by the invention, the copper sulfate can be replaced by 1-5% of potassium permanganate with the purity of more than or equal to 96%; the components are uniformly stirred in the proportions so as to form a product; in a sintering production process, 0.04-0.045 % of the sintered feeding material is added at back of a fuel bin; 5-8% of solid fuel consumption can be reduced; the utilization factor of a sintering machine is increased by about 1%; and the drum strength is improved by 1-2%.

The invention discloses an aluminum electrolysis prebaked anode carbon block coating anti-oxidation method. The surface of a pre-baked anode carbon block is coated with a layer of metal foil or carbonfiber cloth by adopting an adhesive, and the surface of the metal foil or carbon fiber cloth is coated with an anti-oxidation layer. The aluminum electrolysis prebaked anode carbon block coating anti-oxidation method has the beneficial effects that the surface of the carbon block is isolated from air flowing in an electrolytic cell, reliable prevention or alleviation of oxidation of the surface of the carbon block is realized, normal use can be realized in the high-temperature electrolysis environment, the use amount is small, the influence on the quality of aluminum water is small, the environment is protected, energy is saved, and consumption is reduced.
