Properties of alumina based low-cement self flowing
It is found that the self flowing refractory which is prepared by using 0.23 n -value has the best self flowing properties. In addition to these studies different alumina types which affect the aggregate system and the roles of additives (calcined alumina microsilica) are also examined by using n = 0.23 value.
