Compensation system and method for arc skewing for a DC arc furnace

摘要

A DC arc furnace system (10) comprises an arc furnace comprising an electrode (24) extending into a vessel (14). A main DC power supply (28) is connected to the electrode and to an anode region (35) at a base of the vessel by a main furnace circuit (25) comprising an anode conductor (40) connected to the anode region and extending from the anode region externally of the vessel to the main DC power supply. The system (10) further comprises an arc deflection compensation system (50) comprising a compensation circuit (52) separate from the main furnace circuit and which compensation circuit is energized by a compensation power supply (54), which is separate from the main power supply (28). The compensation circuit generates a magnetic field (54) in an arc region (44) of the furnace in a direction opposite to the direction of a field (46) generated by the main circuit (25).
