Abstract :
The paper discusses the design of metallurgical slag and molten metal viscosity measurements. Based on non-Newtonian fluid flow theory and characteristics of metallurgical slag and molten metal, viscosity measurement and calculation, correction and prediction model are established. After reselecting the viscometer material and redesigning the measuring element, the viscometer is suitable for high-temperature molten slag. The method of the parameter adaptive control based on the model optimization is applied to the system to improve the precision. This paper states the effect of this system when it is used in blast furnace production process.
