உருகிய அலுமினியத்திலிருந்து இரும்பை எவ்வாறு அகற்றுவது? தி molten aluminium electromagnetic iron remover is an effective tool for iron removal in the melting process.

அலுமினியம் ஃபவுண்டரி நடைமுறையில் பயன்படுத்தப்படும் மிகவும் பல்துறை பொருட்களில் ஒன்றாகும்; எனினும், iron is one of the most troublesome impurities in aluminium cast materials.

During the solidification of aluminium alloys, iron promotes the formation of intermediate phases, which may damage the properties of the final product.

In secondary aluminium industries, iron contamination caused by high amounts of iron scrap is always possible.

Iron in aluminium, is the most harmful impurities

Iron is considered one of the most harmful impurities in aluminium.

This is especially noticeable in the manufacture of cast aluminium alloys for casting in a metal mold and a sand mold.

Iron along with aluminium and other alloying elements, such as manganese, செம்பு, magnesium and silicon form a phase intermediate iron, that significantly reduces the mechanical properties of the final product.

The main pollution iron in aluminium, occurs during the melting of aluminum scrap, which is mixed with iron.

மேலும், Aluminium scrap itself may contain a high concentration of iron. It belongs, for example, to waste aluminium casting alloys under pressure.

To minimize the problem of pollution of aluminium scrap iron, aluminium industry employs rigorous scrap sorting before loading it into a melting furnace.

This involves manual sorting, magnetic sorting and electromagnetic sorting for sorting crushed scrap particle density.

Iron particles in liquid and solid aluminium

In the conventional solidification of aluminium-silicon casting alloys, the first aluminium phase usually begins to harden.

The other components of the alloy remain liquid and accumulate in the areas between the grains of the primary phase.

Iron contamination causes a change in the solidification sequence of the phases: first the iron-containing intermediate phase appears, and only then crystallization occurs alumina grains.

When these particles are formed before aluminium, they can grow freely and therefore grow in rough crystals surrounded by a liquid phase.

The influence of manganese on the efficiency of iron removal

In the casting of aluminium alloys, it is usually used to reduce the viscosity of aluminium-silicon melts.

Aluminium-iron-silicon alloys have relatively high iron solubility in the liquid phase, even after removing the iron-containing primary crystals.

எனவே, in order to reduce the iron content in the alloy liquid phase, manganese was added to transform the aluminum-iron-Kremin system of the aluminium-iron-manganese-silicon system.

The addition of manganese changes the solidification mechanism, promotes the release of the intermediate phase, which contains iron, and reduces the residual concentration of iron in the liquid phase to an acceptable limit for the casting alloy.

The molten aluminium is maintained at an intermediate temperature between the formation of the intermediate phase and the appearance of aluminium.

At this temperature, the solid phase is separated from the liquid by filtering the melt.

The situation of iron removal from molten aluminium

Metallurgical quality is becoming more and more important to metal casters, and for aluminium casting producers, due to the material cost of aluminium alloys, the problem is even more critical:

The cost of primary aluminium will erode the revenue of large-scale orders, and the low-quality secondary aluminium will reduce productivity for foundries or die-casting plants.

குறிப்பாக, the trace elements of iron-containing materials in recycled aluminium can make the final material brittle and limit its use in high-value automotive or aerospace applications.

Iron is generally harmful to aluminium alloys, leading to the formation of intermetallic compounds.

Iron is concentrated in the continuous recycling process, which makes the recycled aluminium brittle and limits its use in high-end applications such as airplanes.

Existing methods of removing iron from aluminium in the recycling process are either expensive or inefficient.

The effective tool, molten aluminium electromagnetic iron remover

உருகிய அலுமினிய மின்காந்த இரும்பு நீக்கி உருகும் செயல்பாட்டில் இரும்பை அகற்றுவதற்கான ஒரு சிறந்த கருவியாகும்..

The structure of molten aluminium electromagnetic iron remover

There is a heat dissipation layer on the surface of the high-temperature resistant molten aluminium electromagnet iron remover.

The heat dissipation layer can be circulated by the wind to take away the surface temperature of the electromagnet iron remover.

The heat dissipation layer is covered with high-temperature insulation material for heat insulation.

The shell outside of insulation materials is made of Non-conductive steel (stainless steel).

Working principle of molten aluminium electromagnetic iron remover

The shell can be put into a high-temperature furnace up to 800 degrees Celsius, moving back and forth in molten aluminium.

The high-temperature electromagnetic chuck/electromagnet iron remover produces a strong magnetic field at the bottom.

The magnetic field can penetrate the stainless steel protective layer, heat insulation layer, and antipyretic layer.

Attract and remove iron scraps and ferromagnetic impurities in the molten aluminium of the melting furnace, and can generate a magnetic field when energized, and remove the sucked iron parts when the power is off.
