摘 要：By using different particle size of fused white corundum（<74 μm,74～147 μm,>147 μm）,flake graphite,solid resin,commercial alcohol,zirconia（calcium oxide as stabilizer） as the raw materials,Al2O3-C samples with the length of 850 mm,inner（alumina-graphite） diameter of 50 mm and outer（zirconium） diameter of 85 mm were prepared by cold isostatic compaction pressed at 160 MPa after prilling in granulator.An electric field was applied to Al2O3-C refractory and the effect of current intensity（0.5 A,1 A and 5 A） on slag erosion resistance was investigated in this paper.The results show that with the increasing of current intensity,the thickness of build-up in cathode increases significantly.CaO·6Al2O3,a high melting point compound generated on the surface of slag line,decreases the slag erosion rate of Al2O3-C refractory dramatically.
