Furnace Cleaning Flux

图片
  Product description: white powder   Product specification: 20kg/box   Principles and function:   Due to the long-term working state of the melting furnace, it can not be cleaned in time, indicating that a large amount of slag is accumulated around the furnace wall and bottom, which reduces the aluminum melting amount and the furnace efficiency and increases the casting cost.   The traditional cleaning method is: stop the furnace and cool down for a period of time.Then use iron rods and other hard objects to lay down the slag. This kind of way needs intensive labor, and it is easy to damage the furnace, which is a last resort.   The furnace cleaning flux  introduced by SATA can reduce the melting point and viscosity of slag, and make them loose and dry, which can be easily removed from furnace wall and bottom, so as to improve production efficiency, reduce cost and improve product quality.   Instructions:   After the aluminum alloy is melted, the furnace temperature is raised to 800-8

Filtration Mechanism of Ceramic Foam Filter for Casting

图片
  The ceramic foam filter for casting separates the inclusions in liquid casting alloy by three physical and chemical actions of molten metal, so as to achieve the effect of purifying molten metal.   1. Filter cake effect The complex ceramic foam structure can efficiently block the slag mechanically. When the metal liquid passes through the complex ceramic foam filter , the filtration medium can filter out the inclusions larger than the pore size of the filter by mechanical separation, and deposit them in the molten metal's inflow end of the ceramic foam filter. With the increase of inclusions on the filter surface, a layer of "filter cake" will be formed gradually, which will make the metal flow channel become narrower step by step. Therefore, the surface of the new filter medium can filter out the finer inclusions. At the same time,  the inside of the medium also has the function of filtering. In many small holes penetrating through the ceramic body, some have small sli

Production Process of Ceramic Foam Filters for Casting

    1. Sponge processing process   The first is the selection of sponge, because each sponge body may have different mesh even if the same batch of sponges, the mesh standard must be carefully checked before processing; the second is that the cutting size of sponge should be accurate; and finally, the processed sponge products should be guaranteed to have no inclination.       2. Size mixing process   The formula selection must ensure the best condition of the consistency and fluidity of the slurry, so as to ensure that the ceramic foam filters for casting  in the sizing process can be evenly sized and reach the required sizing weight.   3. Sponge modification process   Sponge modification is to prepare for the sizing process, improving the hanging performance of sponge and making a sizing uniform.   4. Dip sizing process   The modified dry sponge products are evenly coated into green bodies by the adjusted slurry on the roller press. For the sponge products with different mesh sizes,

Suggestions on the Use of Ceramic Foam Filters for Casting

  Ceramic foam filter for casting is a kind of porous material, which has a three-dimensional network structure and high porosity characteristics. Its function is to make the disorderly and churning molten metal liquid become stable, uniform and clean after passing the foam ceramic honeycomb hole, thereby greatly reducing the casting reject rate caused by non-metallic inclusions and other casting defects, and saving production costs.   The ceramic foam filter  is made of polyurethane foam as the carrier and is immersed in the slurry made of ceramic powder, binder, sintering agent and suspending agent, etc. Then the excess slurry is squeezed out so that the ceramic slurry is evenly applied to the framework of the carrier to form the green body, and then the body is dried and sintered at high temperature. This process is also known as organic foam impregnation and is a relatively mature production technology in China.   Recommendations for the use of foam ceramic filters:   (1) According

SATA - Professional Potassium Aluminium Fluoride Supplier

  SATA is one of the professional potassium aluminum fluoride suppliers, and can provide you with high-quality potassium aluminum fluoride. Potassium aluminum fluoride produced by SATA can be used as a flux in auxiliary aluminum smelting to reduce or remove the magnesium content in the melt or maximize the metal recovery rate, which is a flux in the metal industry; it can also be used to make grinding wheels (Filler/binder) and other abrasive products.   Potassium aluminum fluoride  (PAF), inorganic salt; also known as potassium cryolite, potassium aluminum fluoride, KAIF. PAF is a kind of high pure inorganic molten salt, which is widely used in industrial production. PAF is often used as filler in the production of abrasives ; it is used as a salt flux in metal processing industry to maximize the metal recovery rate of secondary molten aluminum; at the same time, it can also be used as an additive to accelerate the dispersion and reduce the magnesium content in liquid aluminum alloy.

Introduction of Mg Remover Flux

  In some aluminum alloy manufacturers with special requirements, the magnesium content is too high to make their products meet the requirements of the national standard, but the mg remover flux can reduce the magnesium content in the aluminum alloy to meet the production need of users. With the help of the powder sprayer, the mg remover flux is sprayed into the aluminum molten pool with high-purity nitrogen, and the dispersed mg remover flux chemically reacts with the magnesium in the aluminum alloy, and the reaction material is surfaced to achieve the removal of magnesium.   1. Character:   White powder, 2.5kg/bag       2. Main features   1. It can effectively remove excess magnesium content in aluminum alloy. 2. It has a better refining effect. 3. Instructions   1. Usage of the reverberatory furnace: Use high-purity nitrogen with the powder sprayer to spray mg remover flux  into the aluminum molten pool. The dispersedly sprayed fine mg remover flux chemically reacts with the magnesi

Function and Application of the Granulated Refining Flux

  The refining agent is white (slightly gray) powdery fine particles, the main components are chlorine salt and villiaumite, and  other compounds. After proper heating treatment and screening, the particle size is uniform, which is conducive to the refining tank entering into the lower layer of liquid aluminum evenly. Through physical and chemical changes, numerous small bubbles are formed in the liquid aluminum to fully contact with the liquid aluminum to separate the harmful gases in the liquid aluminum;At the same time, some substances contained in the granulated refining flux can strongly absorb and melt the oxides and suspended solids in the melt and adhere to the bubbles together. With the rising of the bubbles, they will be brought to the surface of liquid aluminum, so as to achieve the purpose of degassing and slag removal. It is environmentally friendly and economical, and can fully produce high value-added, high-tech aluminum alloy precision casting for aviation and transport

Aluminium Covering Flux

  1. Product description Aluminum and aluminum alloy is easy to absorb and oxidize during melting, so it must be protected by spraying aluminium covering flux. When melting, it will form a physical barrier between molten aluminum and oxidation atmosphere in furnace, which will significantly reduce the formation of oxide inclusions in molten aluminum, which is conducive to improving casting quality and product application.   2. Product features It can form a dense protective layer, reduce the entrapment of gas, and reduce the metal loss caused by the oxidation of the liquid surface.It has the advantages of moderate melting point, good fluidity, and good coverage, in addition, it has less consumption, low cost, and low metal content.   Chemical composition and usage: the main components are chlorine salt, fluorine salt, and other salts and compounds. All components are properly treated to remove adsorbed water and crystal water and are screened to ensure uniform particle size. According
