Lining walking-hearth soaking pits furnaces with plastic refractories

Refractories Aims and scope

Conclusions

A scale-resistant shrink-free ramming compound was developed on the basis of chromite ore, electrocorundum, fireclay, and phosphate bond.

Industrial trials were carried out with the compounds in steel factories in furnaces with walking hearths in mills 260 and 350/500. The resistance of the rammed linings in the soaking zone of the furnace was twice that of the resistance of chrome-magnesite brick structure.

Studies of the samples after service established that the compound had been densified in the working zone, possibly as a result of the formation of a mullite growth between the spinel grains.
