TH13729EX - "The lining material for the electric arc furnace using direct current" - Google Patents

Abstract

The lining for the flare furnace between the electrodes in the same circuit uses direct current. Which, at least part of the said furnace area, is made up of a conductive refractory brick lining and an outer ring-shaped conductor forming an electrode opposite to the upper electrode. Extending the middle part into the said stove The lower area is covered with an insulating refractory brick backing and a graphite brick liner is sealed onto the brick lining. In the outer wall of the furnace is radial. Adjacent, there is a herringbone, the inward radius is a ring-shaped zone, which consists of lining Vice conductive refractory bricks In the lower-center area above the insulating brick linings, it consists of a solid clump of a single stone, compressed, and then the furnace material above the aforementioned graphite brick linings as the brick linings. insulator At the bottom of the said stove
