Components: Charging bucket, retort vessel, Lithium store bucket, casting room, cooling water system, argon filling system, electric controlling system
Consuming Melting Furnace Introduction The electrode is melted by the electric arc with high temperature in vacuum and poured into the red copper crucible. Then the casting ingot with high quality can be made.
Main advantages < ;The consuming electrode can be weight automatically.
And the left weight can be displayed and printed at any time. ;
The lifting of electrode has auto and manual controlling
system. It also can be controlled by computer. The melting section can be controlled according to the signal
of weight. ;Coaxial power supply and power auxiliary conducting institution. ;The cooling of crucible is based on the totally closed circuit system of warm water cycle. ;Two furnace ends can share one set of power and one set of vacuum system to improve the
operating factor of the expensive power and vacuum system.
