How to use medium frequency melting furnace to achieve the reuse of metal scrap?

Medium frequency smelting furnace is a kind of high-efficiency metal smelting equipment, which can realise the reuse of metal scrap. The following will introduce in detail how to use the medium frequency melting furnace to achieve the reuse of metal scrap.

First of all: understand the characteristics and principles of intermediate frequency melting furnace

Medium frequency melting furnace is mainly composed of induction coil, capacitor, induction furnace body and water cooling equipment. It heats the metal scrap to the melting point by induction heating, and then pours the molten metal into the mould for cooling to get the recycled metal.

Medium-frequency melting furnace has the features of fast heating speed, low energy consumption and even temperature, which is suitable for the reuse of all kinds of metal scrap.

Step 2: Prepare metal scrap

Metal scrap includes scrap metal, metal chips and waste electronic equipment. Before melting, the metal scrap needs to be classified and processed. The different types of metal scrap are sorted, the attached non-metallic substances are removed, and they are cut or crushed to facilitate heating and melting.

Step 3: Put the metal scrap into the intermediate frequency melting furnace

Firstly, according to the nature and melting point of the metal scrap, adjust the heating parameters of the medium frequency melting furnace, including frequency, power and cooling water temperature. Then, put the metal scrap into the induction furnace body in batches. The appropriate amount of metal scrap will be rapidly heated to the melting point by the eddy current heat generated by electromagnetic induction in the induction coil.

During the heating process, care needs to be taken to control the heating speed and uniform temperature distribution of the scrap to avoid quality problems such as metal oxidisation and burnout caused by excessive or uneven heating.

Step 4: Inverted mould and cooling

When the metal scrap is completely melted, pour the molten metal into the mould smoothly. The shape and size of the mould can be designed according to the requirements to obtain the desired recycled metal product. After the mould has been poured, rapid cooling is required to promote crystallisation and solidification of the metal.

Rapid cooling creates a dense grain structure on the surface of the molten metal and improves the strength and wear resistance of the recycled metal.

Step 5: Handling and processing the recycled metal

The cooled recycled metal product is removed from the mould and cleaned and removed from the surface to remove impurities such as oxides. Depending on the quality requirements of the recycled metal, further treatment, such as heat treatment and shot blasting cleaning, can be carried out.

After Z, the recycled metal is processed and utilised, and can be used directly for the production of new metal products or sold to other enterprises as raw materials.

Summary:

The use of medium frequency melting furnace to achieve the reuse of metal scrap can save resources, reduce environmental pollution, and reduce production costs. By understanding the characteristics and principles of medium frequency melting furnace, preparing metal scrap and heating it to melt, then inverting the mould and cooling it to get the recycled metal, and then treating and processing it after Z, the effective reuse of metal scrap can be achieved. This will play a positive role in promoting sustainable development and environmental protection.
