Abstract

In this  study CaF2 has  been used to make a powder similar to  the  industrial powder. Moreover, TiO2, Na2CO3, MnO, and  ZnO were used in the  composition of mold  powder to reduce or substitute CaF2. A groove viscometer was used to examine the  viscosity of samples and  XRD and  SEM analyses  were conducted to  study the  crystalline  behavior  of samples. Cuspidine phase was the main  phase corresponding to the  sample. White  crystals were grown in the  glass matrix and the existence of these crystals will result viscosity control and  desired lubrication. So utilizing from  MnO in amounts about 4 wt. % (other than the  existing MnO in chemical composition of sample 4) along  with  F– in an approximate amount of 2 wt. %, a  low  fluorine sample was produced. This  low fluorine sample can  be  a substitution for reference sample utilized in steel continuous casting industry. Ill. 6. Ref. 19. Tab. 2.
