How to Extend the Service Life of Aluminum Scrap Melting Furnace?


The service life of the aluminum scrap melting furnace will have a great impact on production costs during production. Thinking of ways to improve the service life of furnaces has become very important for cost saving in most factories. So, how to extend the service life of an aluminum scrap melting furnace? Today, Luoyang Judian will introduce it in detail to everyone.

Aluminum scrap melting furnaces treat waste materials such as waste aluminum alloy doors and windows, waste copper plates, and waste circuit boards. Add these materials directly to the furnace and heat them through electromagnetic induction. Then, melt them at high temperatures to obtain metal recycling of aluminum and copper.

The melting furnace has the advantages of continuous melting, a high degree of automation, and long service life. It is widely used in the aluminum alloy die-casting industry.

Improve the Performance of Refractory Materials of Aluminum Scrap Melting Furnace

The refractory material inside the melting furnace determines its service life. Therefore, to improve the service life of the furnace, you have to work hard on the R&D of refractory materials.

Anti-Aluminum Water Erosion of Refractory Materials

Excellent anti-aluminum moisture with refractory materials can effectively prevent aluminum water from penetrating and prevent aluminum water and aluminum residue. In the refractory material, the SiO2 and impurities are extremely easy to react with Al and Mg in aluminum fluids. Meanwhile, it will cause the volume change of refractory materials, causing the refractory material to form a crack. This will accelerate the erosion of aluminum water to refractory materials. Therefore, the higher the aluminum content of the refractory material, the higher the purity, the better the response to the aluminum water, and the better the corrosion resistance. What's more, external additives can be added to react with molten aluminum to form a protective layer to increase the resistance.

Improve the Wear Resistance of Refractory Materials

The abrasion resistance of refractory materials is mainly to improve their strength. That can effectively increase the resistance of anti-wear and the mechanical impact of refractory materials.

Increase the density of the refractory material and reduce the pore rate of the refractory material

The refractory material itself has high density and low pores, which can effectively prevent the penetration of aluminum and its alloy.

Improve the Heat Resistance Impact Performance of Refractory Materials

Try to prevent the penetration of aluminum liquid, followed by the glass-based layer of dense layer and high viscosity after penetration.

Regular Maintenance of Aluminum Scrap Melting Furnace

Clean the Carbon Accumulation in the Furnace in Time

After a period of time of use, the aluminum scrap melting furnace will get many carbons deposited in the inner wall. This situation will not only affect the efficiency of the furnace but also affect the service life of the stove.

Local Repair of the Slag Line

With the use of a furnace, the slag line will still be slowly eroded and the concave surface becomes deeper. When it reaches a certain depth, we have to remove the slag line brick. Because the upper furnace wall is poured as a whole and has an anchoring hook, it will not collapse. After cleaning up, repairs can be repaired with the repair. The repair of the furnace wall can continue to use 1,000 times in order to extend the service life of the furnace.

The above are several methods for the use of scrap aluminum melting furnaces shared by Luoyang Judian. I hope it will be helpful to everyone. if you have any questions about the induction melting furnace, please get in touch with us. We will respond as soon as possible.
