INTERMEDIATE LADLE LINING GUNITING METHOD Russian patent published in 1995 - IPC

FIELD: metallurgy. SUBSTANCE: method involves preparing basic materials; feeding by gunning machine of dry components and mixer under pressure to nozzle; mixing dry components and applying gunite mixture onto inner surface of ladle lining masonry heated to 100-350 C. Mixing of dry components is conducted in nozzle. Heated surface of ladle is preliminarily coated with 1-2 mm thick layer of carbonaceous material nonsintering with lining; gunite mixture layer of 15-40 mm thickness is applied at the same temperature conditions. The mixture containing, by weight: graphite 32-35, СДБ solution with density of 1,15-1,20 g/cm³ 60-68% is used as carbonaceous layer. EFFECT: increased efficiency. 2 cl
