PERICLASS-SPINELLIDE REFRACTORY Russian patent published in 1999 - IPC

FIELD: refractory industry; applicable in production of periclass-spinellide refractories for lining of metallurgical units, cement rotary kilns and heat units of other industries. SUBSTANCE: periclass-spinellide refractory contains, wt.%: periclass 37-75; ferrichromopicotite 15-45; monticellite 3-6; magnesioferrite 2-4; fort serite 2-4; borosilicate phase with content of B₂O₃ in amount of 9.0-12.0 wt.% 2-5. Presence of borosilicate glass phase in periclass-spinellide refractory ensures higher quality due to increased corrosion resistance to reagents of high basicity, particularly, to slags of steel oxygen-converter production and portland cement clinker. EFFECT: higher efficiency. 2 tbl
