1. 引言粘度是很重要的物理性质,它用以解决炼铁与炼钢过程的实际操作中钢液与铁液的流动性和反应速率的问题.已经进行了许多关于钢液与铁液粘度的研究,但在这些数据之间存在着很大差别(图1),因此迫切地需要铁与铁合金液粘度的精确实验值.回转摆动容器法常常用来测定高熔点金属液如铁等的粘度,因为这种粘度计比较简单而且可用密闭容器.最近,作者指出长期以来认可使用的液体金属粘度和测定的对数衰减值之间的数学方程式并不能提供可靠的粘度值,需要对这些方程式做一些修正.提
1. Introduction Viscosity is a very important physical property that is used to solve the problems of the fluidity and reaction rate of molten steel and molten iron in the actual operation of ironmaking and steelmaking processes.Many studies have been made on the viscosity of molten steel and molten iron (Figure 1), there is an urgent need for accurate experimental values for the viscosity of iron and ferroalloys, which are often used to determine the viscosity of high melting point molten metals such as iron , Because the viscometer is relatively simple and can be used in airtight containers.Recently, the authors point out that the mathematical equations that have long been accepted for use as liquid metal viscosities and the measured logarithmic decrement values do not provide reliable viscosity values, and these equations need to be Some fixes
