MELT-MOULDED HIGH-CHROMIUM REFRACTORY MATERIAL Russian patent published in 2016 - IPC C04B35/12 C04B35/657 

FIELD: metallurgy.

SUBSTANCE: invention relates to production of chromium-containing refractory materials for glass-melting furnaces lining during melting of alkali-free aluminoborosilicate glasses. Proposed is molten fire-resistant material, which components are taken in following ratio, wt%: CR₂O₃ 67.4-90.7, Al₂O₃ 2.6-7.0, MgO 1-2.5, SiO₂ 3-14, Fe₂O₃+ FeO 0.3-3.5, ZrO₂ 1.6-2.4, B₂O₃ 0.2-1.0, TiO₂ 0.2-0.9, and at least one alkali oxide from group of: Na₂O, K₂O, Li₂O 0.4-1.3.

EFFECT: technical result consists in increased output of free of defects (cracks, chips angles) refractory material castings and increased corrosion resistance to action of melts of alkali-free aluminoborosilicate glasses.
