Conclusions
An investigation was carried out of worn roof refractories from two-bath and open-hearth furnaces operated with oxygen blow to accelerate smelting. The wear of the roof bricks in these furnaces is caused primarily by a reactive metasomatosis of the primary high-refractory minerals by secondary low-melting ferrospinels of varied composition, and takes the form predominantly of sweating. In accelerated smelting the metasomatosis is essentially of a ferrous nature.
The interrelation of mineral formation and wear of the roof refractories depends mainly on the conditions of furnace operation, the principal one being the rate of the oxygen blow in the bath.
