STEEL CASTING LADLE Russian patent published in 1997 - IPC

Abstract RU 2095192 C1

FIELD: metallurgy, namely ladles for steel continuous casting. SUBSTANCE: ladle includes metallic body with successive reinforcing and working layers of lining of walls and bottom and seat brick with nozzle placed in bottom. Working layers of wall and bottom lining and seat brick are made of different refractory materials. Lateral walls are made of periclase-carbon bricks, bottom - of periclase-chromite bricks and seat brick - of mullitocorundum at next ratio of ingredients of refractory materials: (MgO + C)/(MgO + Cr₂O₃) = 1.14-1.03; (MgO + C)/Al₂O₃ = 1.11-1.01. EFFECT: improved design. 1 cl, 1 dwg, 1 tbl
