Advantages of steel shell intermediate frequency furnace and aluminum shell intermediate frequency furnace

Many manufacturers have a question when buying an intermediate frequency furnace. What is the difference between a steel shell intermediate frequency furnace and an aluminum shell intermediate frequency furnace? Which one is better to buy? Or which one is more dominant in production?

1. security

First of all, from the perspective of safety, generally large-capacity furnace materials need to be extremely rigid structures, and steel hardness is significantly higher than aluminum. Therefore, the steel shell intermediate frequency furnace is safer and more durable than the aluminum shell intermediate frequency furnace. For example, a 5T aluminum shell intermediate frequency furnace, after filling with molten iron, has an overall weight of 8t, and even more than 10t. When the reducer rotates the furnace body to 95 degrees, the whole furnace body will lean forward, which becomes very dangerous, so the steel shell intermediate frequency furnace is safer than the aluminum shell intermediate frequency furnace.

2. service life

From the point of view of use, the average service life of the general steel shell intermediate frequency furnace is about ten years, and the life of the aluminum shell is only half of the steel shell furnace. Then why? It is also due to the problem of materials. Because of the inherent properties of aluminum shells, aluminum is usually extremely oxidized at high temperatures, and this oxidation reaction causes metal toughness fatigue. We often see some aluminum alloy intermediate frequency furnaces that have been used for only a year or so at the foundry company site. However, due to the small magnetic leakage, the steel shell furnace has a much longer service life than the aluminum shell furnace.

3. energy saving

From the perspective of energy saving and consumption reduction, the steel shell intermediate frequency furnace is also superior to the aluminum shell intermediate frequency furnace. why? In fact, the steel shell intermediate frequency furnace is also called steel shell with yoke hydraulic tilting furnace, and the full name of the aluminum shell intermediate frequency furnace is in the aluminum shell with reducer tilting furnace. From the literal point of view, it can be known that the steel shell furnace uses a yoke, so that the yoke made of silicon steel sheet can shield and emit magnetic lines of force generated by the induction coil, reduce magnetic leakage, improve thermal efficiency, and increase With output, you can save 5%-8% of energy. Therefore, in terms of safety, service life, energy saving and consumption reduction, it is obvious that the steel shell intermediate frequency furnace has more advantages than the aluminum shell intermediate frequency furnace, and is more suitable for the production needs of the manufacturers.
