Conclusions
Roof refractories made using magnesite-chromite clinker obtained from caustic magnesite in the comparative tests had better factors, and a more homogeneous structure than periclase-spinel, and ordinary magnesite-chromite roof refractories. The wear resistance of the roof refractories (in millimeters per heat) made by the proposed technology, using clinker, is 25% higher in average experimental campaigns compared with the three previous campaigns.
