Small high-frequency melting furnace, household electric high-frequency melting furnace, high-frequency melting furnace, metal melting furnace, high-frequency gold melting furnace, high-frequency silver melting furnace, high-frequency copper melting furnace, high-frequency iron melting furnace, high-frequency aluminum melting furnace, high-frequency steel melting furnace, high-frequency tin melting furnace, non-standard customized induction heating melting equipment.
High-frequency smelting furnace is based on the working principle of high-frequency induction heating power supply, using high purity graphite crucible with excellent conductivity and magnetic conductivity as the container, and matching the induction heating ring with the crucible size, which is mainly used for smelting, melting, purifying and refining precious metals such as gold, platinum, silver and copper. Most of them are used to make gold bars, gold, silver and copper jewelry industries. The metal can be quickly melted into liquid in the crucible without loss, and the single melting amount of 2-4 kg can be customized!
Mainframe power supply: All-solid-state MOSFET and IGBT frequency conversion module technology imported from Germany are mainly adopted, and a strong eddy current magnetic field is generated through an induction copper coil, and the metal is instantly heated by induction under the action of the magnetic field, and the temperature rises rapidly.
Main features of high-frequency melting furnace:
1. It is mainly used for melting, refining and purifying precious metals such as platinum, palladium, rhodium, gold, gold powder, sands, silver, copper, zinc, tin ash and tin slag.
2. Fast heating: the fastest heating is less than 1 second, and the heating speed can be adjusted and controlled;
3. It has good electromagnetic stirring effect, which is beneficial to the uniformity of temperature and structure of molten metal, scum and impurity reduction;
4. The frequency range is wide, from 30KHz to 80KHz, and the induction coil and matching capacitor box can be designed according to the specific requirements by considering the melting amount comprehensively;
5. High heating efficiency and low noise during operation;
6. Energy saving and environmental protection: the thermal efficiency reaches over 95%, which perfectly replaces silicon controlled rectifier, gas, ethylene glycol, coke and electric furnace;
7. The highest furnace temperature can reach 1500-2500 degrees;
8. The machine is safe and reliable: the machine is equipped with automatic protection functions such as overcurrent, phase loss, water shortage, overvoltage, short circuit and overheating;
9. The machine is easy to install and operate, and it is professionally debugged before leaving the factory, and it can work without on-site debugging.
