10-300KG Dump Induction melting furnace for copper.brass, silver,gold

Our company's melting furnace mainly uses high-frequency, ultra-high frequency, and medium frequency power supplies produced by our company as the melting host, making the furnace small in size, efficient, energy-saving, and environmentally friendly. Mainly used for melting various metals such as gold, silver, copper, iron, stainless steel, platinum, rare earth metals, silicon nickel lead, etc., with temperatures exceeding 2000 ℃. It is mainly divided into three categories: medium frequency melting furnace, high-frequency melting furnace, and ultra-high frequency melting furnace. The capacity of medium frequency melting furnace ranges from 5 kg to 300 kg, and high-frequency and ultra-high frequency melting is less than 20 kg. The most prominent advantages are small size, energy-saving and environmentally friendly, saving 30-40% of electricity compared to general electric furnaces.

2.Furnace selection, refer to the table below

3. Material selection for crucible:

Ceramic crucible: suitable for melting materials containing Fe elements such as stainless steel and iron, or ultra-high temperature precious metals such as platinum. Common materials include magnesium oxide, silicon dioxide, aluminum oxide, zirconium oxide, etc.
Graphite crucible: suitable for melting materials such as gold, silver, copper, aluminum, nickel, lead, silicon oxide, etc. Common materials include high-purity graphite, silicon carbide, clay graphite, etc.                        
                                                                                             
4. Performance advantages:
(1) Import core Infineon power components, imported chips, Taiwan buttons, etc. to ensure stable equipment quality and a lifespan of over 5 years
(2) It has multiple protection circuits such as overcurrent, overvoltage, internal undervoltage, and frequency discomfort.
(3) It has power, current, frequency, and voltage display, which is intuitive and easier to guide the design of induction coils.
(4) The whole machine runs stably with an extremely low failure rate.
