Abstract
The authors studied on the corrosion of chamotte bricks by various molten steels, with the reformed crucible method.
The results obtained were as follows:
(1) The corrosion of chamotte bricks by the molten steel were influenced by the [Si], [Mn] and [FeO] in the molten Steel
The [Mn] and [FeO] promote the corrosion and, the [Si] hold in check.
(2) If the elements which have great affinity for oxygen were presence in the molten steel, the corrosion decreased.
(3) The corrosion by molten iron and [FeO] increased hastily when [Mn] content in the molten steel decreased.
(4) The corrosive reaction is then According to results of this study, the corrosion by [Mn] in the molten steel is slight in comparison with the corrosion by molten iron or [FeO]. Specially as the [Mn] content is low the controlling reactions for corrosion are (1) and (3) reactions.
