| 摘 要： | 高钛型高炉渣流变特性是影响钒钛磁铁矿高炉冶炼的重要因素,其对炉渣的排放、渣铁分离,甚至炉缸的寿命有重要作用.该研究采用高浓度的丙烯腈-丁二烯-苯乙烯共聚物(ABS)悬浮液模拟高钛型高炉渣体系,用NXS-11A型同轴圆筒旋转黏度计测量其表观黏度,研究了温度、颗粒体积分数及颗粒粒度等因素对悬浮液表观黏度的影响.结果表明:温度和颗粒体积分数对悬浮液的表观黏度影响明显,颗粒粒度对悬浮液表观黏度影响较弱.在较宽的颗粒浓度范围内悬浮液符合Bingham塑性体,并得到了表观黏度与温度和体积分数的二元函数关系式.

| Abstract: | The rheological property of high titanium slag is a main factor to influence the vanadium titanomagnetite smelting in blast furnace.It plays a great role in discharging slag,separating iron and slag and even the life of blast furnace hearth.The acrylonitrile-butadiene-styrene multipolymer(ABS) dense suspension is taken to simulate the system of high titanium slag.Apparent viscosity is measured by a NXS-11A rotating cylinder viscometer.The impact of temperature,volume fraction and particle sizes on the suspe... |
