Tips on using the industrial induction furnace

The main function of the induction furnace is to make steel. Scrap, DRI pig iron, cast iron are input raw materials for induction furnaces.

The enclosure is the outside of the furnace. This houses the crucible and induction coil and has a higher heat capacity. It is made of cuboids and mild steel plates and is joined at the corners by non-magnetic metal corner pieces and edge carriers of the strips.

The development of induction furnaces is therefore good news for small steel producers.

The induction furnace is mainly composed of a crucible, an induction coil, a casing, a cooling system and a tilting mechanism. The crucible is made of refractory material, and the furnace plate is lined with refractory material. The crucible holds the charge and subsequently the melt.

The choice of refractory material depends on the type of charge and basically consists of acidic, basic or neutral refractory materials.

Our electric furnaces produced by Judian are easy to install, operate and maintain. These furnaces have smaller thermal dimensions and lower investment costs, making them the first choice for steel mills with lower capacity. In these furnaces, steel is produced by melting the charge using the heat generated by an electromagnetic field.

The proportions of these items and the techniques for melting these input materials vary depending on the availability of raw materials and the location of the plant. Producing a specific quality of steel requires further selection of raw materials.

For better and more efficient smelting in an induction furnace, the raw material charge must meet the following criteria.

Compaction of dense waste is important to ensure uniform and rapid heating and energy savings.

Clean The content of rust, oil and sand is preferably zero.

Metallurgical cleaning i.e. no slag lumps, oxides etc., especially for DRI, slag and ferroalloys.

There are no or very few sharp sharp edges, especially in the case of heavy and large scrap.

Electricity is the only energy source for steelmaking in induction furnaces. Induction furnaces operate at maximum power from the start.

There is some misconception here that the low is first released and then gradually raised to the higher. Maximum power input increases the melting rate, thus reducing the cycle time for heating. Also monitor the voltage drop of the power supply to improve energy efficiency. Further power consumption rates depend on furnace size.

Of course, when we buy electric furnaces, we should pay attention to the after-sales service and preliminary guidance of the merchants.

That's what we share today. Luoyang Judian is a manufacturer of induction furnaces, welcome to follow us, you can learn more about metal melting furnaces.
