摘　　要：根据冶金熔体的物理化学性质,可以确定冶金熔体是属于粘性流体。利用同一牛顿流体在任何剪切速率下的粘度相同这一特点,给出了一个用拟牛顿流体原理检验冶金熔体的流动特性的方法。将普通固定转速高温粘度计改造为可调转速,可测出熔体的流动特性,进而能确定熔体是否为牛顿流体。Metallurgical melt can be treated as viscous fluid according to its physiochemical chacteristics. Based on the fact that a newtonian flunid has the same viscosity at any shear rate, a method for determining flow characteristics of metallurgical melt by the principle of quasi-newtonian fluid is proposed in this paper. With a modified high temperature speed adjustable rotational viscometer, flow characteristics test of melt was carried ont. Based on the test vesults, it can be concluded whether the melt is newtonian fluid or not.
