    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 dispersed...

    In the process of refining and transportation of molten metal, foreign matter such as oxide scale, intermetallic compounds, and hearth fragments are easily brought into the molten metal to form non-metallic inclusions.   These non-metallic inclusions are mainly oxide inclusions. Aluminum alloy casting refining flux can remove these impurities, thereby improving the purity of aluminum alloy.   The production method of aluminum alloy casting refining flux is as follows:   Fusion method:   The high melting point (for aluminum alloy) inorganic salt according to the low eutectic point ratio is subjected to high temperature dehydration and high temperature melting treatment to produce a low melting point mixed salt, which is then crushed into blocks or powdered after condensation. This method is dehydrated thorough.   When using the fusion method to make refining flux, you can first melt the low-melting chlorine salt, add refractory ingredients at a cert...

  Aluminum alloy casting refining flux can remove oxide impurities, thereby improving the purity of aluminum alloy.   The production method of aluminum alloy casting refining flux is as follows:   1. Drying and mixing method   The required salt is fully dried and dehydrated, and then the distribution ratio is formed according to the eutectic point of the high-temperature molten salt, and some components that are beneficial to dehydrogenation and slag removal are mechanically mixed. This method is used to prepare simple refining flux with low quality requirements. Commonly used raw materials for selection include NaCl, Na2CO3, KCl, MgC12, Na3AlF6, BaC12, NaF, K2CO3, etc.   The production process of the drying and mixing method is:   Drying-ingredients-mixing-packaging-products   Drying and mixing method can produce non-toxic aluminum alloy casting refining flux, the main component of non-toxic refining flux is NaNO3+C (graphite), and then adding an appr...

    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 a...

  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. 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 spon...

  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 slit...
