Wettability of tundish periclase lining by steel

Results of a study of the wettability of the tundish periclase lining by molten steel using a sessile drop method are presented. The wetting angle θ tends to decrease with increase in temperature and contact time on adding glass fiber and Fe₂O₃ powder in excess of 2% to the magnesite powder; a similar effect is observed in steels high in manganese. An increase in angle θ is observed on adding carbon fiber or glass fiber (not in excess of 1%) to the magnesite powder; the angle θ tends to increase with increase in MgO powder grain size and with carbon contained in steel in excess of 0.04%. __________ Translated from Novye Ogneupory, No. 1, pp. 63–68, January, 2006.
