Conclusions
Magnesium-silicate refractories — dunite, talcomagnesite and olivinite — react with basic open-hearth slag, forming both low-melting phases (pyroxeme-type mineral and monticellite) and high-melting phases (periclase and composite spinel).
The preliminary test on magnesite-silicate refractories as lining for steel-casting ladles have shown that the slag adheres and becomes welded to the refractory to an appreciable extent.
The hypothesis has been expressed that this adhesion is due to the appearance of periclase and composite spinel in the contact zone — slag from high-melting interacting products — and that these two minerals apparently increase the viscosity of the melted slag.
