When users buy a new electric furnace, they need to choose a furnace body. Common furnace bodies include steel shell furnaces and aluminum shell furnaces. Today, Hongteng editor will introduce the difference between these two kinds of furnace.

The steel shell furnace has a long service life, which can reach more than 10 years. The magnetic permeability is good, and the steel shell furnace is 3 to 5 percent higher than the aluminum shell furnace node. The pouring is destined to be stable, and the pouring angle and speed can be very good. Good safety performance, good characteristics in the tonnage greater than 2T above the choice of steel shell structure domain.

The aluminum shell furnace has a simple structure. The service life is 5 to 8 years. It is suitable for the capacity of less than 2 tons, there is no magnetic conductor, the furnace lining ejection mechanism, the refractory cement layer, and the safety performance is poor.

For example: a set of 5 tons of intermediate frequency furnace, when the furnace is full of molten iron, the overall weight of the equipment reaches 8 to 10 tons, if the aluminum shell structure is selected, when the reducer rotates the furnace body to 95 degrees, the whole furnace body tilts forward, and the safety performance is very poor . The aluminum shell furnace is suitable for users who change production in a short time, with small tonnage.

The advantage of the steel shell furnace is that it is sturdy and durable, beautiful and generous, the furnace body has a large capacity, and has a tough and rigid structure. From the safety point of view of the tilting furnace, try to use the steel shell furnace.

The presence of the furnace cover reduces heat loss and also improves the safety of the equipment.

The steel shell furnace has a long service life, and the aluminum shell is oxidized seriously at high temperature, resulting in the willful fatigue of the metal.

At the casting site, we often see aluminum shell furnaces that have been used for about a year. Less magnetism, the life is much longer than that of the aluminum shell furnace.

Ordinary steel shell furnace will increase power consumption by about 10% compared with aluminum shell furnace! If users use ordinary steel shell furnaces, they may consume hundreds of thousands of kilowatt-hours of electricity a year, and steel shell furnaces require multiple technologies to reduce losses.

Steel shell furnaces have high, medium and low grades, and the price of different configurations will vary by tens of thousands. And the price of steel shell furnace will be much more expensive than aluminum shell furnace.

Luoyang Hongteng is a professional manufacturer of electric furnaces, whether it is a steel shell furnace or an aluminum shell furnace, we can provide it.
