REFRACTORY STONE FOR LINING METALLURGICAL UNITS Russian patent published in 1997 - IPC

Abstract RU 2082928 C1

FIELD: ferrous and nonferrous metallurgy; metallurgical surfaces; arches of electric and open-hearth furnaces. SUBSTANCE: side faces of auxiliary section of refractory stone having optimal geometric sizes have recesses while opposite faces have mating projections. Adjacent refractory blocks are mated forming continuous geometric structure whose locking portion keeps separate blocks from falling out in case of damage to suspension system. EFFECT: enhanced thermal resistance of lining; enhanced tightness of brickwork and reduced losses of heat into surrounding medium. 2 cl, 2 dwg
