A barrier layer on a refractory lining is formed. The method includes providing a refractory-lined vessel containing a combination of aluminum oxide and calcium oxide that can form a precipitate when exposed to chlorine. The combined aluminum oxide and calcium oxide is exposed to chlorine, whereby the precipitate is formed and deposited on the refractory lining, thereby forming the barrier layer on the refractory lining. In a preferred embodiment, the method includes injecting chlorine or a chlorine-containing compound at a point beneath a surface of a molten bath in said vessel to form the precipitate, whereby the precipitate accumulates on a surface of the lining, thereby forming the barrier layer. |
