Detailed Description

1. Type of molten steel furnace :

The molten steel furnace is a power-saving type product, which adopts a half-bridge parallel inverter intermediate frequency power supply (voltage resonance , whether the electric furnace is cold state, hot state, plus half charge or full material, the half bridge parallel inverter can output the rated Power, power factor is constant at 0.9 6 . ) The molten steel furnace is safe and reliable, in line with national standards and related regulations.

The molten steel furnace has the advantages of high automation level, advanced technology, mature, accurate and reliable control, mature manufacturing process, safe and stable operation, perfect protection system, reasonable layout and convenient management and maintenance. It has the characteristics of fast melting speed , low energy consumption and stable and reliable operation.

2. The composition range of this molten steel furnace :

Transformer → secondary copper discharge → intermediate frequency power supply → capacitor cabinet → furnace body → hydraulic tilting furnace system → remote control box → closed loop cooling tower → water cooled pipeline.
