In casting and rolling production, the requirements for melt modification are very strict, especially for direct casting and rolling of electrolytic aluminum liquid. A slight negligence may cause malignant defects and lead to product scrapping. For example, in the casting and rolling process of capacitor materials, slight composition fluctuations may affect the final performance. In order [...]
At the beginning of the new year, everything is new, and Xuansn Electronics Co., Ltd. has welcomed a group of new faces. In order to better integrate the new forces into the team, feel the warmth of home, and enhance the new employees' sense of belonging to the company, the company organized various departments to carry [...]
1 Control the composition ratio of electrolytic refining agent When using electrolytic refining agent, it is especially important to ensure the content of Na3AIF6. Of course, NaCI cannot be used to replace KCI. The purpose of ensuring the content of Na3AIF6 is to reduce the wetting angle between the slag particles in the melt and the medium, [...]
As mentioned above, the gas content and slag content in the electrolytic aluminum body melt are far greater than those in the remelted aluminum liquid. The solubility of the gas dissolved in the aluminum liquid decreases as the temperature of the melt decreases. During the casting or rolling process, the melt cools rapidly and solidifies into a solid, [...]
1 Characteristics of electrolytic aluminum liquid Electrolytic aluminum liquid is produced by high-temperature electrolysis of aluminum oxide in the presence of certain electrolytes (such as cryolite, etc.) using a special process. The temperature of electrolytic aluminum liquid is generally between 920 and 950°C, and the residence time in the tank is long. The aluminum liquid is extracted from the [...]
