1. Considering the production cost, certain amount of aluminum scrap was added when manufacturing the aluminium alloy. The scrap is mainly the components of old automobiles and equipment. The content of Magnesium will be too much higher in these scrap and the unsteady content of Magnesium occurs in some Magnesium alloy castings. This will failed in producing the required standard alloy ingots. In order to lower the magnesium content, some foundries wash by using high purity aluminium ingot. This method can achieve the goal .The large quantity of high purity aluminium ingot consumption increases the production cost and complicated the production process. 2. The effective operation of Magnesium removing is required if the Magnesium content is beyond stipulation in case of using aluminum scrap for alloying. SATA magnesium remover flux gives you the best solution. Our flux is easy in use with its excellent performance. Removing magnesium and refining at same time. Jinzhou Sata Fused Flu

Adding a small amount of fluorine salts such as NaF,Na3AlF6,CaF2 to the chloride salts, mainly for refining such as absorption melting Al2O3, fluoride salts can also effectively remove the oxide film on the surface of the melt, improving the effect of degassing, the reasons are follows: 1. Fluoride can be separated from aluminium melt and chemically react to form gaseous AlF,SiF4,BF3 etc, they promote the separation of oxide film from aluminium melt by mechanical action, squeeze the oxide film and push it into the solvent. 2. The current generated at the interface where the above reaction occurs also causes the oxide film to be “washed out” and broken. Therefore, the presence of fluorine salts accelerates the destruction process of the oxide film on the surface of the aluminium melt, and the hydrogen in the melt can more escape conveniently. 3. Chloride salts, especially CaF2 can increase the surface tension of the mixed molten salts, make the molten salt of the adsorbed oxide sphero

1. 1000 series alloy: Representative: 1050,1060,1070,1000 series aluminium plate is also called pure aluminium plate, 1000 series alloy has more al content and the purity can be over 99.00%, because it don't contain other technologies element and the production process is relatively single, so the price is relatively cheap, it is commonly used in the conventional industry at present, Most of the current circulation in the market are 1050 and 1060 series, the aluminium content of the 1000 series aluminium plate is determined by the last two digits. Such as 1050 series, must contain more than 99.5% aluminium. 2. 2000 series alloy: aluminium-copper alloy, representative: 2A16 (LY16), 2A06 (LY6), the characteristic of the 2000 series alloy are: high hardness, copper content is about 3-5%, 2000 series aluminium plate belongs to aviation aluminium. 3. 3000 series aluminium alloy, aluminium manganese alloy, representative: 3003,3A21, it is also called as rust-proof floor aluminium plate,

Metal additives also be called alloying tablet is a kind of novel product that can replace the master alloy. It was mixed proportionally by pure metal powder with certain fluxing agent then pressed to a tablet form. Metal additives can simplify the aluminium alloy smelting technology, save power and raw material, reduce the production cost. Most important, it can help the foundry to control accurately the alloying element, enhance the product quality. Metal additives are with features of high metal content, small bulk, easy to transport as well as convenient in application. Advantages of Metal Additives: 1. With average element content. 2. With low melting point, reduce the aluminium and alloying element buring loss. 3. Lower down the production cost. 4. Excellent addition principle and convenient application 5. Steady element actual absorption rate and economic production method. Application of Metal Additives: Directly added into smelting furnace is acceptable. Also, can be added i

Fluxes composed of chlorine and fluorine containing salts are used for degassing molten aluminum alloys. Degassing fluxes are commonly shaped in form of tablets. Degassing operation starts when a flux tablet is plunged by a clean preheated perforated bell to the furnace bottom. The flux components react with aluminum forming gaseous compounds (aluminum chloride, aluminum fluoride). The gas is bubbling and rising through the melt. Partial pressure of hydrogen in the formed bubbles is very low therefore it diffuses from the molten aluminum into the bubbles. The bubbles escape from the melt and the gas are then removed by the exhausting system. The process continues until bubbling ceases. Degassing flux may also be introduced by an injection method. In this case the inert gas serves as carrier for granulated flux. Besides the degassing effect the degassing treatment allows removing non-metallic inclusions suspended in the melt (cleaning effect). Hydrogen, found in the foundry primarily d

Al-Mg alloy is the heat-treatment and non-reinforceable alloy, the main element in alloy is Mg, it is widely used in the automotive industry, home appliance industry, electronics industry and construction industry, and it has the advantage of high strength, good formability and corrosion resistance, compared with 1xx series alloy and 3 series alloy, it isn’t easy to control and easily cracking during the production. With the improvement of equipment level and operation level, the probability of casting cracks is currently very low, but another phenomenon has occurred during the production. it is completely normal, and then the ingot is heat rolled after multi-milling and soaking. When the rolling thickness reaches around 100mm, cracks start to occur at the edges and ribs of the material, and they continue to be thinned,When the thickness reaches around 60mm, the local crack on the edge of the ingot has reached 200mm, and it is no longer possible to continue rolling. This is the pheno

In the normal composition in the Aluminium alloy flux, the commonly recipe including fluorides and chlorides, rare earth compounds should be used as preferred additives, including rare earth halides, rare earth carbonates or other rare earth compounds. In addition, K2CO3, Na2CO3, CaCO3, NaF, KNO3, CaCl2, CaSO4 and graphite can be used as auxiliary additives as required. The role of each component: (1) Fluoride: It plays a refining role, it can absorb and dissolve Al2O3, and it also can properly control the melting point of mixed salts to increase the purification effect. As a surfactant, alkali metal fluoride salt can reduce the surface tension between the flux and the melt, and between the flux and the oxide inclusions. The limited solubility of alkali metal salts in oxidized inclusions ensures that the flux can penetrate the oxide film. Common fluoride salts such as Na3AlF6, CaF2 and Na2SiF6 can be added to 20% (mass fraction). CaF2 can also increase the surface tension of the mixed
