ELECTRIC ARC STEEL-MAKING FURNACE LINING Russian patent published in 2003 - IPC

Abstract RU 2211421 C1

FIELD: ferrous metallurgy. SUBSTANCE: proposed lining consists on water- cooled tubular panels in form of spirals and refractory brickwork. Water- cooled panels are located on side of inner surface of brickwork in slots formed by even and odd rows of bricks at depth equal to 1.10-1.25 of diameter of tube. Ratio of area of heat-absorbing surface of tubes to area of surface of refractory brickwork is equal to 0.3-0.5. EFFECT: enhanced resistance due to effective cooling; reduced power requirements. 2 dwg
