Refining Flux Can Improve the Metal Smelting Process

图片
  Refining flux  can be widely used in metal smelting and foundry industry. It is compounded by multiple elements, which is more beneficial to metal smelting after adding. In the process of smelting, it is difficult in deoxidation, desulfurization, dephosphorization, and degassing. Using the refining flux during the smelting process, various impurities can be effectively removed, which make the metal more pure.   Adding refining flux is more conducive to metal smelting   If the gas and impurities cannot removed in time during the metal smelting process, it will occur defects such as pores, cracks, cold insulation, and shrinkage, which will result in product quality degradation. After adding the refining flux, the technical deficiency encountered in the metal casting process can be eliminated. The flux can also achieve the effect of grain refining, the fluidity of the metal can be enhanced, and the impurities of the metal melt can be eliminated in time.   In addi...

Method of Distinguishing the Quality of Anhydrous Magnesium Chloride

  Anhydrous magnesium chloride   ( mgcl2 anhydrous ) is mostly produced by the evaporation and purification of seawater, salt lake and salt well water. These resources are abundant and cheap.  The magnesium chloride anhydrous melting point  should be realized. There are also some anhydrous magnesium chloride is produced by purification of some industrial by-products, such as the by-products of Production titanium sponge production. After purification, Anhydrous magnesium chloride is obtained. The magnesium chloride obtained by this method has high purity and contains less impurity.   As we all know that the magnesium chloride is a water-soluble chemical substance, but impurities in anhydrous magnesium chloride, such as magnesium sulfate, sodium chloride, and potassium chloride (commonly known as salt impurities) do not react with magnesium oxide. There impurities not only reduce the purity of anhydrous magnesium chloride, but more importantly, these impurities h...

A356 Series Alloy

    A356 series alloy is a typical Al-Si-Mg series ternary Aluminium alloy. A356 series casting alloy has excellent comprehensive properties. Its casting mold can be very good. It is often used to cast some thin-walled and complex-shaped castings. Meanwhile, due to that the alloy is handled by heating method, the alloy has high strength, excellent plasticity and impact toughness. Therefore, A356 alloy was widely used in the automotive industry in the late 1980s. Currently, cast aluminum alloy wheels are still dominated by A356 alloys at the worldwide market. With the development of the level, the design requirements of the automotive industry are constantly increasing, so that more and more of these alloys are applied to the casting of automotive industry parts, which has led to increasing requirements for the raw material of A356 aluminum alloy. Process characteristics, raw materials have a crucial effect on the quality of castings, which means that while pursuing high-qualit...

Selection of Chemical Composition of 6063 Aluminum Alloy

  6063 aluminum alloy is widely used in the construction of aluminum doors and windows and curtain wall frames. In order to ensure that the doors and windows have high wind pressure resistance, assembly performance, corrosion resistance and decorative performance, the comprehensive requirements for aluminum alloy profiles are far higher than those of industry. Profile standards, within the composition range of 6063 aluminum alloy specified in Chinese national standard GB / T3190, different values of chemical composition will result in different profile characteristics. When the range of chemical composition is large, the performance difference will be very large. The range fluctuates, so that the overall performance of the profile cannot be controlled. Therefore, it is preferable that the chemical composition of 6063 aluminum alloy becomes the most important part of producing high-quality aluminum alloy building profiles.   1. The role of alloying elements and its effect on pr...

Aluminium Modifier - Al-Sr Alloy

图片
  In metal materials, aluminum and its alloys have been widely used in automobile, motorcycle and other aluminum alloy casting production because of its low density, high plasticity, good conductivity, good corrosion resistance, rich resources and easy processing. As a metal modifier, Al-Sr alloy is safer and more effective than salt. The results show that aluminium modifier Al sr improved by SATA can optimize the form and distribution of eutectic silicon, improve the mechanical properties of the material, and reduce the tendency of thermal cracking to the greatest extent.   1. Performance features: 1. The structure of aluminium modifier  is excellent, which can optimize the morphology and distribution of eutectic silicon and improve the mechanical properties. 2. Easy to use, pollution-free with little loss and long-lasting effect. And the effect of remelting and metamorphism can be inherited.   2. Scope of application: It is suitable for modification of hypoeutectic...

  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.   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 smelting furnace, and increases the burning loss of aluminum and alloy elements. The smelting productivity is also reduced...
