Characteristics of Unburned Magnesla-Titania-Alumina Brick

摘要

In Japan it is feared that the import of flake graphite becomes difficult and also that its price will rise further, because the consumption of the material in some of the producing countries is now increasing. On the other hand, it is pointed out that magnesia-carbon bricks containing a large amount of flake graphite (hereafter called MgO-C bricks) have the weak point of a carbon pickup into steel. Therefore, the authors considered that the rapid development of low carbon MgO-C bricks or no carbon MgO bricks is necessary. This paper presents the investigation results of unburned MgO system bricks containing no carbon.
