【 摘 要 】

Issues of viscosity and rheological properties of powder moulds are important from the perspective of modelling, along with the control of continuous casting process. Conducted analysis within subject literature indicates that there are many theoretical considerations concerning the effects of viscosity of powder moulds. The objective of this study was to perform rheological measurements of powder moulds, the study contains the results of rheological tests of seven chemical compositions with a carbon content from 5.0 to 10.7% and which were tested with applied shear rates from 10 to 40 s-1, which are similar to those in a real process: the velocity of strand passes/drawing and mould movements.
