Aluminum Melting Furnaces

Induction Melting Furnace for Aluminum

Aluminum is the most commonly used non-ferrous metal today, other than iron. In 2012 the amount was approximately 45 million tons. It is also number 3 in terms of its abundance, following only silicon and oxygen. Aluminum resists corrosion more than most other metals. It is also prized for its reflective properties. Aluminum is a metal that is often recycled and reused, such as soft drink and beer cans. Aluminum is used in the transportation industry, aerospace industry, construction, household products of all kinds, electronics, packaging, electrical lines and even in paint, among many other applications.

Aluminum melting furnaceBecause it is considered to be a lower density metal, the aluminum melting furnace is specifically designed for the purpose of melting aluminum. Lower density metals like aluminum require evenly distributed heat for melting, and the heat must be maintained at a precise temperature. Induction type aluminum melting furnace, utilizing an alternating current coil (electromagnetic induction) to melt the aluminum. Water is used as a coolant for the system.

This type of melting furnace is much more capable than others of producing the even and precise temperatures necessary for processing aluminum. In an induction melting furnace the action of the electromagnetic field actually stirs the aluminum as it melts, allowing the aluminum to maintain its integrity. Any impurities will rise to the top when melted and the pure aluminum will sink to the bottom.

The aluminum melting furnace is clean (non-polluting), energy-efficient, easy to control and can melt aluminum quickly. Induction furnaces in general are far less expensive to  the operating and maintenance budgets, as well.

When selecting your aluminum melting furnace, you have several factors to consider relating to the furnace specifications, and depending on the volume of material to be processed and produced. These factors include:Aluminum melting furnace

    • Melting Rate which refers to the amount of aluminum to be melted within a specific time period.
    • Utilization Factor refers to the amount of time involved in any action which is not melting.
    • Certain tasks must always be performed, meaning that melting does not occur 100% of the time.
    • Furnace Yield is the amount of molten metal which can be expected to be obtained in a certain time period after taking into consideration the utilization factor.
    • Casting Yield refers to the amount of the final cast product. In order to determine this figure losses from pouring and molding must be taken into account in order to determine the amount of aluminum to be melted to achieve the required amount of finished product.
    • Pouring Rate is determined based on the above factors and the thermal efficiency of the system.
    • Performance Index is calculated from what the furnace takes and the melt rate that it gives.
