【 摘 要 】

This paper presents the results of the rheological analysis of selected grades of steel: 90CrV6, DHQ3, 34CrNiMo. In metallurgical processes, gradient of the dynamic viscosity parameter is an important indicator characterizing the behavior of liquid metal in the industrial aggregates. It affects the processes of heat exchange and mass transport occurring in the existing liquid, solid and gaseous phases. Only a small number of high temperature viscosity measurements is available. This is due to the fact that the experiments are difficult to conduct and due to the general assumption that the molten steel is a liquid exhibiting similarities to Newtonian liquids body.
