粘度是冶金熔渣、熔融硅酸盐等熔体的一个重要物理化学性质。粘度的研究具有十分重要的意义。目前,国内外广泛采用的是内圆柱体旋转法。其特点是适应于变化范围较大的熔体粘度的测量,但其缺点是测量精度较低,内圆柱体旋转时摆动产生测量偏差等等。这种落后的方法与工业发展是不相适应的。为了开展炉渣粘度研究工作,我们研制了一台具有光电脉冲数字显示记录系统的吊丝旋转粘度计。一、原理本装置属于内圆柱体旋转粘度计,所谓
Viscosity is a metallurgical slag, fused silicate melt an important physicochemical properties. The study of viscosity is of great significance. At present, widely used at home and abroad is the inner cylinder rotation method. Its characteristic is to adapt to the larger range of changes in the measurement of melt viscosity, but the disadvantage is the measurement accuracy is low, the inner cylinder rotating swing measurement deviation and so on. This backward method is incompatible with industrial development. In order to carry out the study of slag viscosity, we have developed a filament rotary viscometer with digital photo recording system. First, the principle This device belongs to the inner cylinder rotation viscometer, the so-called
