APPARATUS FOR DRYING LINING OF STEEL CASTING LADLES Russian patent published in 1997 - IPC

Abstract RU 2095191 C1

FIELD: metallurgy, namely apparatuses for drying lining of tar-pitch bonded refractory materials of steel casting ladles. SUBSTANCE: apparatus for drying lining includes cover with axial opening. Gas burner is arranged with gap in that opening. Said burner has two coaxial tubes spaced one from another by gap. Rod is placed in duct of inner tube, lower part of outer tube has inner cone. Diameter of said rod consists (1-3)δ, value of intertube gap - (30-200)δ, cone angle is equal to (10-40)degrees, thickness of outer tube end consists (1-3)δ, distance from ends of tubes and rod until cover - (50-80)δ, distance from ends of tubes and rod until bottom of ladle - (140-230)δ, gap between outer tube and said axial opening of cover - (4-12)δ, where δ - intertube gap width. EFFECT: improved design. 2 dwg, 1 tbl
