COMPOSITION FOR MOULDED OR UNMOULDED REFRACTORIES OR FURNACE ACCESSORIES Russian patent published in 2015 - IPC C04B35/101

Abstract RU 2539056 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to fire-resistant composition containing from 70% by weight up to 98% by weight of loose fire-resistant material, and from 2% by weight up to 30% by weight of binding phase, including the active filler and cohesive agent. The named binding phase in essence includes exclusively reactive andalusite, with the average grain size d50 between 0.2 microns and 2,0 microns and narrow particle-size distribution with the width by the particle sizes in a range below 2.5 microns, as the active filler.

EFFECT: improvement of composition properties.
