Repair & Overhaul
Repair work comprises the targeted overhaul of damaged or worn areas of the refractory lining – without relining the entire furnace.
What does Repair involve?
Not every instance of damage calls for a complete relining. With targeted repairs to the affected areas, we bring your furnace back into production quickly and economically. Whether localised wear, cracking or mechanical break-outs – we identify the damage precisely and repair it professionally.
Our repair team has many years of experience with all established repair techniques: from conventional brick replacement through casting repairs and gunning to hot repairs on furnaces that have not fully cooled down. In many cases this allows us to intervene without a complete shutdown.
At SBS Refractory Service, cost-effectiveness is the priority. We advise you honestly on whether a repair makes sense or whether a partial relining is the better option. Every repair is fully documented and feeds into our recommendations for the next maintenance interval.
At a glance
- Short shutdown possible (typically 1–5 days)
- Hot repairs sometimes possible without a full shutdown
- Safety concept for work on hot furnaces
Step by step to the result
Structured, transparent and on schedule — this is how we work.
Damage assessment
Visual inspection and damage analysis
Our specialists examine the damaged area visually and by measurement. The remaining wall thickness is determined by ultrasonic testing or laser measurement. Based on the findings, we produce a precise damage map.
Repair concept
Definition of method, material and scope
Depending on the type and extent of the damage, we select the optimum repair technique: brick replacement, casting repair, gunning or hot repair. The concept takes into account the remaining service life of the surrounding lining and the next scheduled overhaul.
Execution
Targeted repair of the damaged areas
The repair is carried out by experienced refractory installers. For hot repairs, special heat-resistant equipment and techniques are used. Every work step is documented and all materials used are recorded with their batch numbers.
Acceptance
Quality inspection and documentation
Once the repair is complete, a visual inspection and, where applicable, a leak-tightness check are carried out. You receive a detailed repair report with photos, material specifications and recommendations for ongoing monitoring.
