High Impedance Electric Arc Furnace

Equipment feature: the main loop series-wound reactor can raise the system impedance; realize secondary high voltage, long electric arc low current operation. The EAF’s electric arc is stable and the electric arc power is high. The furnace is operated under on-load voltage regulation. The EAF have right and left operation form & the cover is revolving type. Feeding from the top, EBT tapping.

Furnace body is frame type water cooled structure. Upper shell & lower shell are removable. Furnace cover is concentric circles tubular water cooling structure. Furnace gate carbon oxygen lance furnace wall burner.

Proportion valve controls the electrode lifting, furnace swiveling & furnace body tilting.

Whole set PLC & computer control system, computer picture monitor system & neural network AI electrode controller system.

Whole set scope for equipments: furnace body, furnace tilting mechanism, electrode lifting mechanism, furnace cover lifting swiveling device, cooling water & it’s display & alarm device, hydraulic station, compressed air system, feeding system, high voltage switch system, transformer, series reactor，low voltage power supply system, computer control system & picture monitor system, neural network AI electrode controller system.
