Deslagging Machine is an important equipment to remove the hydrogen content, inclusions and alkali metals in molten aluminum.
The solubility of hydrogen in molten aluminum is very high, which will reduce the physical properties and machining performance of castings. To cast high-quality castings, the hydrogen content in molten aluminum must be controlled at a low level.
The rotor of the degassing refining equipment can effectively break the inert gas into tiny bubbles, which are evenly dispersed and floated in the molten aluminum.
The partial pressure of hydrogen in the molten aluminum is higher than that in the bubbles. The hydrogen will diffuse into the inert gas and float to the surface with the bubbles, thereby effectively reducing the hydrogen content in the molten aluminum. At the same time, the floating bubbles will cause small inclusions in the molten aluminum. Brought to the surface of the molten aluminum, captured and removed by the covering agent.
1. Is there any optimization for aluminum alloy casting?
In the aluminum alloy, if its composition is different, then the physical or chemical properties will be different, which is also different in the characteristics of the aluminum alloy. Therefore, it is necessary to make a reasonable selection of the casting method, so as to effectively avoid some casting defects or problems, thereby ensuring the casting effect.
2. What are the properties of the aluminum alloy used in aluminum alloy casting? Is it widely used?
These two questions,
The specific answer given by AdTech Metallurgical Materials Co., Ltd. is:
The aluminum alloy used in aluminum alloy casting, from a professional point of view, is a non-ferrous metal structural material, and its application can be said to be very wide, in aerospace, automobile, shipbuilding, machinery manufacturing and chemical industry There are a large number of applications in China, and there are more and more requirements.
3. During the aluminum alloy casting process, if the degassing and slag removal are not performed, what impact will it have on the casting? And can additives be used for degassing and slag removal?
In the aluminum alloy casting process, if the degassing and slag removal is not possible, the impact on the casting is mainly due to the two defects of blisters and pores, and this is affirmative. Therefore, additives can be used for degassing and slag removal, but it is necessary to select the appropriate one and control its dosage to have a good use effect.
