Measurement Method for Rheological Characteristic of Metallurgical Melt

A measurement method for the rheological characteristic of metallurgical melt by means of a modified rotational viscometer with variable speed used at high timperature was proposed. The rheological characteristic of molten slag measured with the modified viscometer has been investigated. Therefore, revisory method of the rheological parameters has been put forward and the revisory constitutive equations have also been camed out.
