Apply electromagnet iron remover to remove iron impurities from molten aluminum
Heat-resistant electromagnet iron remover quickly removes iron impurities from molten aluminum, can be worked at 800℃ high temperature, improve the quality of aluminum ingot and aluminum casting product.
In the aluminum alloy ingot and secondary aluminum recycling industry, there will be a problem for iron impurities.
That is, it is necessary to charge aluminum scraps or aluminum ingots into the melting furnace for smelting and melting.
When aluminum scrapes are melted into aluminum liquid under high-temperature heating,
But in the melting process, iron impurities are unavoidable in aluminum scraps.
If iron impurities are not removed quickly, it will definitely affect the quality of aluminum products, especially the elemental composition in aluminum alloy ingots or casting, causing the aluminum product to be unqualified, or unsuitable for casting.
The impact of aluminum alloy adc12 iron exceeding the standard on die casting:
If the iron content is too high, it is easy to form an Al-Fe-Si phase rich in iron and silicon with Si.
And Al-Fe-Si is combined to exist in the alloy in the form of flakes or needles, reducing the mechanical properties.
The structure will also reduce the fluidity of the alloy and increase the hot cracking.
Because the adhesion of aluminum alloy to the mold is very strong.
It is especially strong when the iron content is below 0.6%.
When it exceeds 0.6%, the mold sticking phenomenon will be greatly reduced, so the iron content should generally be controlled within the range of 0.6-1%, which is good for die-casting, but the maximum should not exceed 1.5%.
Electromagnet iron remover development
For the existence of iron impurities in aluminum ingot and casting, our engineers analyzed the technical data from many cases.
We have developed a heat-resistant electromagnet iron remover that can remove iron impurities from high-temperature molten aluminum.
It can be immersed into the molten aluminum of the melting furnace to stir the high-temperature aluminum liquid, and the ferromagnetic substances will be sucked out.
Remove iron impurities such as iron scrap and iron products from molten aluminum, and improve the quality and application range of recycled aluminum products.
Iron remover working principle
There is a heat dissipation layer on the surface of the heat-resistant electromagnet iron remover.
The heat dissipation layer can circulate the wind and take away the surface temperature of the electromagnet iron remover.
The heat-dissipating layer is wrapped with high-temperature insulation material for heat insulation.
The heat-resistant material is covered with a shell made of non-magnetic steel (stainless steel).
The electromagnet iron remover can be immersed into a high-temperature furnace up to 800 degrees Celsius and stirred back and forth in the molten aluminum.
The bottom of electromagnet iron remover/electromagnet chuck generates a strong magnetic field.
The magnetic field can penetrate through the stainless-steel protective layer, heat insulation layer, and heat-dissolving layer.
The iron impurities and ferromagnetic impurities in the molten aluminum are adsorbed and removed.
The magnetic field can be generated by powering on.
The iron scraps to be absorbed can be removed when the power is turned off.
Can the iron core in electromagnet iron remover be replaced with copper or aluminum?
The answer is absolutely not.
When the electromagnet iron remover is energized, the electricity becomes magnetic, and it can absorb iron materials
But not copper and aluminum.
The iron core in the electromagnet iron remover has the following characteristics:
1. The material is silicon steel sheet, which has strong magnetic performance.
2. It is made of multiple silicon steel sheets overlying, each sheet is 0.3~0.5mm thick to reduce the loss of magnetic conduction.
Copper or aluminum does not have the above properties, so they cannot replace iron core in electromagnet iron remover.
Not only molten aluminum electromagnet iron remover, but also aluminum dross machine.
