Melting furnace manufacturer: Understanding the classification of melting furnaces is key to making a better choice.

A melting furnace is a piece of equipment used to melt metal ingots and some scrap metal, add the necessary alloying elements, and then, through processes such as slag removal and refining, produce the desired alloy.

Is the safety of the medium-frequency furnace guaranteed?

Some people say that using medium-frequency furnaces is dangerous. In fact, any piece of equipment carries some degree of risk—but the typical risks usually stem from the equipment itself not being sufficiently well-designed or constructed. So, is the safety of medium-frequency furnaces guaranteed? Let’s first take a closer look at what medium-frequency furnaces are.

Maintenance Knowledge for Medium-Frequency Furnaces

When adding metallic materials into the medium-frequency furnace, their size should be appropriate—specifically, they must not exceed half of the furnace’s static volume. Moreover, the charge materials should be added in small batches and multiple times. When introducing larger pieces of material, it’s advisable to first add some smaller-volume materials as a base layer. This approach ensures that the materials won’t get stuck and also reduces the impact force exerted on the furnace bottom and walls by the metallic materials.

Installation Requirements for Medium-Frequency Furnaces

The medium-frequency furnace is a device that can convert 50-hertz alternating current into medium-frequency current—ranging from above 300 hertz to 1,000 hertz. After rectification, it transforms three-phase power-frequency AC into direct current, and then converts this DC into adjustable medium-frequency current, which is supplied to capacitors and induction coils, generating a medium-frequency alternating current that flows through them. As a result, a magnetic flux with high density is induced in the induction coil.

Methods to Extend the Lifespan of Medium-Frequency Furnaces

During maintenance, the furnace body of a medium-frequency furnace needs to be sintered. However, if the medium-frequency furnace has never been used before, it’s necessary to apply a lining to the furnace. Performing this lining operation is particularly beneficial for protecting the furnace body. Before starting the lining process, you need to prepare the appropriate materials and then create a protective layer inside the furnace body of the medium-frequency furnace.

Do you know how long a medium-frequency furnace can last?

Do you know how long a medium-frequency furnace can last? Under operating conditions characterized by relatively thin cross-sections and exposure to highly corrosive environments during numerous melting operations, the primary process parameters influencing lining damage are the melting temperature, degassing time, initial degassing volume, chemical composition of the slag, and the type of steel (or iron) being produced. The main factors contributing to lining failure are chemical erosion by the slag, spalling of the refractory material structure, and thermal erosion.

Introduction to the Working Principle and Features of Medium-Frequency Furnaces

The medium-frequency furnace generates a medium-frequency power supply through a rectifier-inverter composed of thyristors, which is then transmitted to the furnace coil. A medium-frequency electromagnetic field is generated between the furnace body (coil), inducing eddy currents in the metal within the furnace. These eddy currents generate substantial heat within the metal, thereby melting it.
