A Study on an Oscillating-plate Viscometer for Instantaneous and Simultaneous Measurements of the Viscosity of Melts and the Noise with their Chemical Reactions

Abstract

In order to understand various phenomena in the metallurgical processes, a new oscillating-plate viscometer using a non-contact electro-optical system connected with a signal separator has been made on an experimental basis.
The apparatus allows us not only to give instantaneous and continuous indications of the product of density and viscosity (ρμ) of a liquid being in a state of unsteady flow with fair accuracy, but also to make simultaneous measurements of ρμ and noise during chemical reaction.
It is expected that the data obtained experimentally on the changes in viscosity and noise with slag/metal reactions may provide us any useful information about a degree of chemical reactions and dynamical behaviour of the reaction products.
