Abstract:
Disclosed is a cement-free high strength unshaped refractory in which barium aluminate and a dispersant are further added to a refractory which includes a refractory material containing Al2O3 and SiC and an alumina sol binder to largely improve handling strength of the unshaped refractory. The unshaped refractory according to the present invention is usefully applicable to lining which contacts slag in a blast furnace or a gasifier.
