Abstract
For most cases, remaining thickness and quality of the refractory lining is key to continuous operation of pyrometallurgical vessels in the copper industry. Melt penetration within refractory lining can result in delamination or, in severe cases, refractory lifting within the hearth of a flash or converting furnace. Formation of cracks and delaminations in hearth, sidewalls and roof refractory lining can lead to melt infiltration and increased likelihood of run-outs. Important areas such as tapholes should be constantly monitored for refractory deterioration within the tapping channel. Better lancing or drilling practice can be developed based on the feedback from such monitoring systems leading to increased tonnage of material tapped between each repair.
