Small horizontal vacuum induction melting furnace

Description of induction furnace

The small horizontal vacuum induction melting furnace is a standard compact temperature controlled induction heating / melting system with complete accessories. Such a complete system includes 15kw induction heater, quartz tube with flange and valve, graphite crucible and refractory components, 58L / M circulating water cooler, vacuum pump and mobile trolley. It is an ideal tool for crystal growth, melting and sintering of new metal alloys with melting point < 1700 ° C (in vacuum or protective gas environment).
