Detailed Introduction of 20kg Medium-frequency Aluminum Melting Furnace
In the field of metal smelting, for experimental scenarios requiring miniaturization and high precision, the 20kg medium-frequency aluminum melting furnace has become an indispensable assistant for many scientific research institutions and laboratories due to its unique advantages. It is specially designed for the smelting of aluminum and aluminum alloys, capable of meeting diversified experimental needs and helping researchers work efficiently.
I. Working Principle
This medium-frequency aluminum melting furnace operates based on the principle of electromagnetic induction heating. The medium-frequency power supply converts three-phase power frequency alternating current into medium-frequency alternating current and transmits it to the induction coil. The induction coil generates an alternating magnetic field, which induces an electric current in the aluminum charge inside the furnace. Due to the resistance of the aluminum charge, energy loss occurs when the induced current passes through, generating heat. As heat accumulates, the temperature of the aluminum charge gradually rises until it reaches the melting state. Meanwhile, the electromagnetic stirring effect of the medium-frequency magnetic field promotes uniform temperature and composition distribution of the aluminum melt, improving smelting quality.
II. Product Features
1. High Efficiency and Energy Saving
Adopting advanced medium-frequency induction heating technology, it features high energy utilization, saving over 40% energy compared with traditional resistance furnaces. When smelting 20kg aluminum, it effectively reduces energy consumption costs and improves energy efficiency.
2. Precise Temperature Control
Equipped with a high-precision temperature control system, it can monitor and precisely regulate the furnace temperature in real time, with a control accuracy of ±2ºC. This is crucial for aluminum alloy smelting experiments sensitive to temperature, ensuring the accuracy and repeatability of each experimental result.
3. Safety and Reliability
The furnace shell is made of high-temperature resistant insulating materials (temperature resistance ≥1200ºC), with a surface temperature ≤50ºC, effectively preventing operators from scalding. The equipment is also equipped with multiple safety mechanisms, including overload protection, leakage protection, and over-temperature alarm, to fully guarantee the safety of the experimental process.
4. Easy Operation
The operation interface is simple and intuitive, allowing even novice operators to master the operation quickly. Moreover, the equipment is compact and lightweight, occupying less than 1 square meter, making it easy to place and move flexibly in limited laboratory spaces.
5. High Smelting Quality
The magnetic stirring effect of the medium-frequency magnetic field significantly improves the uniformity of the aluminum melt composition, effectively reducing element segregation in aluminum alloys and ensuring the smelted aluminum liquid meets high-standard experimental requirements.
