Welcome to the top 20 | aluminum industry growth
Analysis of the growth of main aluminum products since the 18th National Congress of the Communist Party of China.
TMS International Academic Conference has been included in the schedule
Fujian Metal-new Aluminum Technology Co., Ltd. will participate in the 2023 Annual Meeting and Exhibition sponsored by the American Society of Minerals, Metals and Materials (TMS) in San Diego, California, USA on March 19-23, 2023. The conference will focus on "a new green solution technology for aluminum alloy" in light metal casting workshop technology, and will conduct academic discussions with scholars from all over the world.
In the short term, aluminum prices rebounded and came under pressure again
Introduction: The Federal Reserve rate hike landed in July, basically in line with market expectations, and the US dollar index continued to fall. Overseas Lun aluminum first showed a rebound trend, domestic Shanghai aluminum driven by the rebound, but in the context of off-season demand, aluminum ingot inventory began to accumulate, and aluminum prices rebounded again under pressure.
Principle and source of gas and inclusion in liquid aluminum
When the alloy is in solid state, the solubility of the gas is very small, and the melting degree increases slowly with the increase of temperature. When the melting point of the alloy is reached, the melting degree suddenly increases rapidly. When the alloy is melted and then heated up, the melting degree increases faster, because the melted alloy has a very active chemical reaction with the atmosphere, absorbs hydrogen, and is oxidized and produces oxides. It also consumes the effective components in the molten liquid, which reduces the quality of the solution, or forms defects such as pores and slag inclusion.
Why is liquid aluminum degassed?
Because aluminum is less dense than most metals, it has a softer texture. Appear light. If there is air at the time of pouring, it will be easier to mix in liquid aluminum than other metals, and the pouring will form porosity defects. Affect its use, so that castings scrap.
