 Technical program and specification

This program is recommended that whole set equipment of the furnace shall be equipped with two furnace bodies user can be readjusted by practical needs.

1.1 Technical program

The main equipment of this program is included 2 13000KVA rectification

transformer, 4 low voltage control cabinet, 4 power supply cabinet, total power is 26000KW. 2 50t MF induction furnace, 1 hydraulic station (double motor double pump, type electromotion), 1 cooling water device, and other auxiliary device. The electric system diagram is as follows
