发明名称 Yttira containing high-density chrome based refractory composites
摘要 The invention presents yttira elements containing high-density chrome based refractory composites, which consist of: (A) Fused polymeric compound as aggregate, containing: 40 to 50 wt % of particles in size from 1 to 4 mm and 15 to 25 wt % of particles in size below 1 mm; (B) A matrix consisting of fused polymeric compounds with particle sizes below 66 mum, active sintered Al<SUB>2</SUB>O<SUB>3</SUB>, active industrial Cr<SUB>2</SUB>O<SUB>3 </SUB>and Y<SUB>2</SUB>O<SUB>3</SUB>. (C) Binders accounting for 2.5 to 3.5 wt %. Since Y<SUB>2</SUB>O<SUB>3 </SUB>has resistance to the slag corrosion and penetration with its compatibility with slag, it has been introduced to activate the major component Cr<SUB>2</SUB>O<SUB>3 </SUB>crystal lattice in favor with Al<SUB>2</SUB>O<SUB>3 </SUB>so that it helps to reduce the sintering temperature, increase the rate of finished products as well as reduce the manufacturing cost.
