MIX FOR PRODUCTION OF REFRACTORY WITH FORSTERITE BOND

摘要

FIELD: metallurgy.;SUBSTANCE: this mix comprises granular periclase, dispersed periclase, granular magnesian-silicate component, dispersed magnesian-silicate component and binder. Note here that said granular periclase is a vitrified periclase with density of at least 3.30 g/cm³ and/or fused periclase. Mix dispersed component is the mix of periclase with MgO weight fraction over 97% and magnesian-silicate component and/or zirconium silicate at the following ratio, in wt %: granular periclase with weight fraction of MgO of 93-97% - 50-80, granular magnesian-silicate component - 5-30, dispersed component of the mix of periclase with weight fraction of MgO over 97%, and magnesian-silicate component and/or zirconium silicate - 15-35, and binder over 100% - 3.5-5. Dispersed component of the mix contains additionally the zirconium dioxide ZrO₂ or titanium dioxide TiO₂.;EFFECT: good resistance to cyclic thermal effects and corrosion.;3 cl, 1 tbl
