Refractories Aims and scope

Conclusions

The use of blocks for lining steel discharge apertures substantially reduces the number of repairs, and cuts their work content.

The resistance of periclase-spinel blocks and blocks made from brine magnesia is 80–81 heats.

The maximum resistance (132 heats) was achieved by using blocks made from fused magnesite.
