摘　　要：以攀钢实际生产高炉渣(CaO-SiO_2-Al_2O_3-MgO-TiO_2)为基础,制备不同TiC含量的渣样,研究从1500℃到1450℃含钛熔渣的触变特性、电流变特性以及爬杆现象等非牛顿流体现象。结果表明:渣样含有8%的TiC,具有明显的触变特性。渣样中不含TiC,剪切应力的上行曲线与下行曲线重合,无触变特性;渣样中TiC质量分数为4%、8%,剪切应力随电场强度的增大而增大,又随电场强度的减小而减小,熔渣具有明显的电流变特性。渣样中TiC质量分数为0时,渣样的剪切应力不随电场强度变化而变化;不同含量TiC的渣样均不具备爬杆现象。Slag samples were based on the on-site slag （CaO-SiO2-A1203-MgO-TiO2） of Panzhihua Iron and Steel Corporation. Non-Newtonian behaviors, thixotropy, electrorheological effect and rod-climbing effect were investigated from 1500℃ to 1450℃. The result shows that the slag sample containing 8% TiC has an obvious thixotropy. While for the slag sample without TiC, the up line of shear stress coincides with the down line which means no thixotropy is observed. A remarkably electrorheological response is observed in slag system with 4%TIC and 8%TIC, and the shear stress increases with increasing the electric field and decreases with decreasing the electric field. For the slag sample without TiC, the shear stress is not altered by the electric field. Neither the slag system containing TiC or not containing TiC shows a rod-climbing effect.
