摘要

By using diferent particle size of fused white corundum ( < 74 μm, 74 - 147 μn, > 147 μn), flakegraphite, solid resin, commercial alcohol, zirconia ( calcium oxide as stabilizer) as the raw materials, Al2O3-C sampleswith the length of 850 mm, inner ( alumina-graphite) diameter of 50 mm and outer ( zirconium) diameter of 85 mmwere prepared by cold isostatic compaction pressed at 160 MPa after prilling in granulator. An electric field was applied toAl2 O3 -C refractory and the efect of current intensity ( 0. 5 A, 1 A and 5 A) on slag erosion resistance was investigated inthis paper. The results show that with the increasing of current intensity, the thickness of build-up in cathode increasessignificantly. CaO · 6A12O3, a high melting point compound generated on the surface of slag line, decreases the slagerosion rate of Al2O3-C refractory dramatically.
