PDFAll furnace typesRepair or reline? The three findings
When a targeted repair is enough, and the three findings where only a relining will hold.
Wear is rarely evenly distributed — frequently only 20 to 30 per cent of the lining has reached the end of its service life. A blanket complete relining pays more than necessary.

Complete replacement or repair relining? On industrial furnaces this question often decides five-figure sums. From more than 500 refractory projects we know that wear is rarely evenly distributed. Frequently only 20–30 % of the lining has reached the end of its service life — the rest is still sound. A blanket complete relining therefore pays for material and downtime that would not be necessary.
The basis for every recommendation is an honest condition assessment — including thermography and documentation. Because not every damaged spot is suitable for a partial repair. The decision to repair or replace should be based on data, not on routine.
