It is common for researchers to believe that liquid slag is a fluid characterized by rheological behavior of ideally viscous Newtonian body. At the same time it is assumed that the fluid is similar to synthetic polymers in terms of its structure. The authors of this paper conducted research into 4-component liquid and solid-liquid synthetic slag system: CaO–SiO₂–MgO– Al₂O₃ The research involved graphite measurement systems. A perforated spindle was used for the solid-liquid systems subject to shear stress, whereas a smooth one was used for fully liquid systems. Both measurement systems worked according to Searle’s system. This paper presents selected rheological research results concerning oxide solutions in high temperatures and their rheological analysis.

Wśród badaczy panuje powszechny pogląd, że ciekły żużel jest cieczą wykazującą zachowania reologiczne ciała doskonale lepkiego Newtona. Zarazem przyjmuje się, że jest on cieczą o podobieństwie strukturalnym do polimerów syntetycznych. Autorzy artykułu wykonali badania czteroskładnikowych ciekłych oraz stało-ciekłych żużli syntetycznych systemu: CaO–SiO₂–MgO– Al₂O₃. Do badań wykorzystano grafitowe systemy pomiarowe. Systemy stało-ciekłe poddawano działaniu naprężeń ścinających z wykorzystaniem wrzecion perforowanych dla systemów całkowicie ciekłych użyto wrzecion gładkich. Obydwa układy pomiarowe pracowały w systemie Searle’a. W artykule zaprezentowano wybrane wyniki badań reologicznych roztworów tlenkowych w wysokich temperaturach oraz ich analizę reologiczną.
