Silicon-aluminum alloy production process and components of slag cleaning agent
Thread Content
I urgently need to understand the production process of silicon-aluminum alloy. I hope someone who knows can give a detailed introduction. I also learned from the Internet that silicon-aluminum alloys are prone to oxide scale during smelting. There is a unit that sells a slag cleaning agent to remove this oxide scale. I wonder what the ingredients of this so-called slag cleaning agent are and how effective it is in removing oxide scale? I hope someone who has used it can tell me about it.
When we produce aluminum-silicon master alloy, there is basically no oxide scale. However, it is best to explain the silicon content of the aluminum-silicon master alloy. We have made it from 10, 20, 30, and 50.
The silicon content is above 25%. It is impossible not to have oxide scale. Water vapor and oxygen in the air can easily oxidize aluminum. Moreover, the surface of the raw material will also be oxidized in the atmosphere. After melting, the oxide scale will float on the melt. I don’t know how your company handles this, could you please give me more details? Thanks
We use aluminum ingots and crystalline silicon in the production process. We use slag breakers and refining agents for slag degassing. During the casting process, we use a casting machine and only need to perform necessary surface scraping.
The deslagging agent and refining agent you are talking about should be NaCl, KCl, cryolite and other salts, right? I don’t actually want to obtain aluminum-silicon alloy. I am using aluminum-silicon alloy to do some purification processing. The temperature is around 700~750°C. Can you tell me the suitable salt components and their proportions at this temperature? The main thing is that the melting point is appropriate, there is no decomposition, and the dissolution of aluminum and silicon is small.
My company needs to die due to work needs: Al=1: 4 (mol) aluminum-silicon alloy, Al, Si% ≥ 95, particle size less than 100 mesh, does your company have it? What is the approximate price? Can you provide a small amount of samples (2kg)
