How much electricity does an induction furnace use?

To gauge the typical energy consumption (kWh) of an induction furnace, it’s insightful to refer to specific studies. One such study undertaken for the US Department of Energy reveals interesting figures. It shows that well-run heel melters in induction furnaces have an average energy consumption of up to 800 kWh per ton. This is in comparison to batch melters, which typically use around 530 kWh per ton. These numbers give us a clear understanding of the energy requirements for different types of induction furnace operations.

 

Can gold be heated by induction?

Absolutely, gold can be effectively and efficiently heated using induction technology. With the capability to melt up to 10 kg of gold in less than 20 minutes, induction heating stands out as a remarkably fast and reliable method. But it’s not just limited to gold. This technology is equally adept at melting other metals like silver and brass, as long as they have a melting point below 1300°C.

In practical applications, like in gold melting, induction heating has proven its worth. We’ve successfully demonstrated how this method not only melts the gold but also ensures it is thoroughly homogenized. Once melted, the gold can be seamlessly transferred from a tundish into a granulation tank for further processing. This process underscores the efficiency and effectiveness of induction heating in handling precious metals.

What is the difference between melting and smelting?

While both melting and smelting involve heating substances to high temperatures, the key difference lies in their outcomes and purposes. Melting is the process of transforming a solid substance into its liquid form without changing its chemical composition. This process is typically used to liquefy metals, facilitating further manufacturing or processing.

On the other hand, smelting is a more complex chemical process. It involves not just heating an ore beyond its melting point but also often using oxidizing agents like flux. The purpose of smelting is to extract pure metals or simple metal compounds from their ores. For example, the extraction of gold from its ore requires smelting. This process alters the chemical composition of the ore to separate the desired metal in its purest form.

In summary, melting is about changing the state of metal, while smelting is about extracting and purifying metals from their ores through a combination of heat and chemical reactions.

 

What are the disadvantages of induction melting?

While induction melting offers numerous advantages, it’s important to be aware of its limitations. The primary drawback of an induction furnace is its lack of refining capacity. This means that the materials you place inside the furnace need to be free from oxidation products and their composition must be well-known.

This limitation is significant because, during the melting process, some alloying elements might be lost due to oxidation. As a result, these elements may need to be reintroduced to the melt to achieve the desired alloy composition. It’s a factor that requires careful consideration and planning, especially in processes where precise alloy compositions are critical.
