Induction Vacuum Melting System IMSV-250-2,4-0,15
IMSV-250-2,4-0,15 is designed for melting and casting of cobalt, nickel or iron alloys in vacuum and inert-gas atmosphere. It is a system for investment and cavityless casting of complicated formed parts (turbine buckets, wheels, basic parts, etc.).
Induction Vacuum Melting System IMCV-250-2,4-0,15 comprises:
• vacuum melting chamber with induction coil;
• vacuum loading chamber;
• evacuated lock-chamber;
• SCR frequency converter ТПЧР-250-2.4;
• two dual-circuit cooling systems (CS-40W и CS-80W);
• capacitor unit;
• set of busbars;
• Electrical equipment control cabinet;
• two remote control boards;
• operating deck;
• vacuum system (pumps, pipe lines, etc.);
• hydraulic system.
