Development of MA—C Refractory for Smelting—reduction Iron—Making Process

摘要

A kind of carbon-bering refractory (MA-C1) has been developed for smelting-reduction iron-making process and its physical chemistry properties were measured,Smilting-reduction slag (15 wt% FeO) resistance of the developed refractory has been compared with commercially available refractories by curcible test,static slag soaking test and fractal dimension analyses,The results show that slag resistance of the developed refractories(MA-C1) is better than those of alumina-carbon refractory (AM-C1),alumina-magnasia-carbon brick (AM0(J)) ,and Si3N4-SiC brick.
