Melting characteristics of MF induction furnace have been expounded with comparison with that of mains frequency induction furnace as well as concerns in operation.

Products are melted by the intermediate frequency electric furnace and processed by numerical control processes.

A catalyst factory has improved the lining ramming technology of GW-0.15-2.5 medium frequency melting furnace. Thus the lining life has been prolonged and the quality of melted material also improved.
