  The aluminum alloy casting refining flux is white powder, which is mixed and prepared by a certain proportion of a variety of inorganic salts after drying treatment. It is mainly used to remove the floating oxide slag in the aluminum alloy.   In the aluminum alloy casting and smelting process, the aluminum alloy casting refining flux is added into the melt, and the aluminum alloy casting refining agent can remove metal impurities, oxides and oxides from the melt through physical, chemical or physical-chemical interactions. Other oxide inclusions and so on.The impurity removal ability of the refining agent is determined by the adsorption and dissolution of the refining agent on the oxide inclusions in the melt and the chemical effect between the refining agent and the impurities in the melt.     The smaller the interfacial tension between the aluminum alloy casting refining flux and the inclusions, the better the adsorption effect of the refining agent and the stron...

  Alumina ceramic foam filter is a kind of porous material, which has a three-dimensional network structure and high porosity characteristics. Its function is to make the turbulent and churning molten metal become stable, uniform, and clean after passing through the foam ceramic honeycomb holes, thereby greatly reducing the casting waste rate caused by casting defects such as non-metallic inclusions and saving production costs.   Problems that should be paid attention to in the use of alumina ceramic foam filter:   1. In order to ensure the full filtration of the molten metal, the filter must have a certain pressure head for starting filtration to overcome the obstacle of surface tension. The pressure head size has a considerable effect on the start of the filter. Generally, it should be greater than 400mm. For large castings, the indenter should be correspondingly larger.   2. The overlapping part of the alumina ceramic foam filter and the mold should be sealed as f...

For small castings of aluminum alloy and other light alloys, you can choose alumina foam ceramic filters whose thickness is less than 15mm, and for large castings of non-ferrous alloys, ...

    With the rapid development of the foundry industry, the requirements for the cleanliness of molten metal and the performance of castings are getting higher and higher. In recent years, the ceramic foam filter has been widely used in casting production, and it has become the simplest and most effective method to improve the mechanical properties of castings and reduce pores and inclusions.   At present, there are more and more manufacturers producing alumina ceramic foam filter in China, the production and use of alumina ceramic foam filters have also increased significantly, but the product quality is uneven, which brings trouble to casting manufacturers in choosing alumina ceramic foam filters. If the selection is not appropriate, not only the expected results cannot be achieved, but it will bring more trouble to the casting production and even increase the rejection rate of castings. Therefore, the reasonable selection and correct use of alumina foam ceramic filters...

  The covering flux is a covering material that can extend the solidification time of the molten metal in the riser and cover the surface of the molten metal in the riser during casting production. There are two types of covering fluxes: thermal insulation covering fluxes and heat-generating covering fluxes.  We provide refining flux , alumina ceramic foam filter , grain refiner for aluminium , magnesium flux , electrode flux material an d s o on.   The characteristics of the covering flux are as follows:   1. The thermal insulation covering flux is made of low thermal conductivity materials, such as expanded perlite, expanded graphite, etc.   2. In addition to the low thermal conductivity material, the heating covering flux is added with a certain proportion of heating materials. Under the heat of the molten metal, the oxidant provides oxygen to oxidize the reducing agent and generates heat, thereby prolonging the solidification time of the molten metal in...

    In order to improve the properties of aluminum, it is necessary to add various alloy elements to make different grades of alloy. At present, alloy or pure metal is basically used in China. Some domestic aluminum processing plants have replaced the master alloys with aluminum alloy additives. From the application effect, it can be seen that the additives not only have all the advantages of the master alloys, but also overcome some disadvantages of the master alloys, so the additives are more and more widely used.  Our company sell cover flux aluminium , degassing flux , drossing flux , Granular Flux , aluminum flux powder ,etc.   Product advantages of aluminum alloying additive tablets Aluminum alloying additive tablets is much better than master alloys because of its good adding mechanism, convenient use method, the stable actual yield of elements, and economic production mode.It avoids excessively high temperature, which leads to the reduction of the life of the...

    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 aviati...
