Use of magnesite concrete in open-hearth furnaces

Conclusions Many years practical experience with the use of refractory magnesite concretes in open-hearth furnaces at the KMZ confirmed that it is rational to use them even for preparing concretes and blocks on the working sites of open-hearth shops, and it also confirmed the unacceptability of open-hearth furnace structures for placing the concretes.A project for a furnace framework should be developed bearing in mind the use of blocks of maximum sizes which will accelerate repairs.Simultaneously with the increase in the output of chrome-magnesite mixture for the production of concrete it is necessary to produce this mixture with greater fineness for the wash materials.Translated from Ogneupory, No. 6, pp.31–35, June, 1972.
