Product introduction
Melting furnace refers to the equipment that melts metal ingot and some scrap metal and adds necessary alloy components, and melts them into needed alloy through slag picking and refining operations.
2. Classification: Experimental small furnace , medium frequency furnace, high frequency furnace
3. Adjustable temperature: 0-2000℃
4. Temperature and melting time needed: depends on different furnace models and metals.



Product application
Medium frequency power supply of 200~2500Hz is used for induction heating, power range of 20~2500KW, melting furnace can also be called medium frequency electric furnace according to its characteristics. Mainly used for precious metals such as gold, platinum, silver, copper, iron, stainless steel, aluminum alloy, aluminum and other metals melting and warming, is the ideal equipment for university laboratory, research institute, hand decoration processing, investment casting processing. The power supply adopts IGBT imported power devices, which is more integrated and miniaturized. The effective output power reaches more than 90%, saving energy and 60% energy than the traditional thyristor medium frequency!
Working principle
The melting furnace uses the medium frequency power supply to establish the medium frequency magnetic field, which generates eddy current inside the ferromagnetic material and generates heat to achieve the purpose of heating the material. Medium frequency electric furnace adopts 200-2500Hz medium frequency power supply for induction heating, melting and insulation, melting furnace is mainly used for melting carbon steel, alloy steel, special steel, can also be used for copper, aluminum and other non-ferrous metal melting and temperature. Equipment small size, light weight, high efficiency, less power consumption, melting temperature fast, easy to control the furnace temperature, high production efficiency.
Main characteristics
The main characteristics of melting furnace are: light equipment, fast heating speed, high efficiency; Special power saving, the same load than the electron tube high-frequency machine save 60%; With over current, over voltage, overheating and other protective functions, simple operation, easy installation, suitable for all kinds of metal heating occasions.
