ResumoA bstract An analysis of “how a blast‐furnace lining wears out” is presented. The conclusions drawn are the result of critical studies on three furnaces as their linings were being removed for relining. Scab and scab‐refractory interface samples were taken at 3‐ft. intervals. These were analyzed and studied petrographically. Alkali attack and carbon disintegration are concluded to be the most serious causes of lining wear and deterioration in the stack, whereas insufficient refractoriness and high porosity are concluded to be the sources of trouble in the hearth.
