Raw aluminium and its alloys have the following characteristics due to production relations:
Raw aluminium and its alloys have the following characteristics due to production relations:
1, at this stage, the original aluminium and alloy is used as molten salt electrolytic salt water from the aluminium electrolytic cell production and manufacturing, are liquid.
In the process of aluminium electrolysis production, because the temperature of the electrolytic cell is around 960 ℃, the temperature of the original aluminium and alloy is very high. The lithium bromide solution is transported from the electrolytic process industrial plant to the forging production workshop, which is generally above 900°C.
3. The content of hydrogen and other vapors in liquid primary aluminium is relatively high, and it still reaches 0.4ML/100g (AL) at 800 ℃ after aluminium extraction.
4. There are more non-metallic materials in liquid primary aluminium.
