REFRACTORY MASS Russian patent published in 2000 - IPC

Abstract RU 2151127 C1

FIELD: machine engineering, metallurgy. SUBSTANCE: invention relates to refractory mass for foundry production. Refractory mass has the following components, wt.-%: refractory clay, 99.98; boric acid, 0.02. Mineralographic composition of the main elements of calcined refractory articles is the following, wt.-%: Al₂O₃, 25; SiO₂, 48.58; B₂O₃, 0.0113. Refractory articles made of proposed refractory mass are caked at lower temperatures, they have increased (by 1.5-2-fold) resistance to slag effect, high mechanical indices. EFFECT: improved quality and properties of mass. 1 tbl
