Fire Proof Bricks Lining Services
Refractory brick installation for furnaces, boilers and thermal process equipment — high-alumina brickwork built for sustained heat cycling by RK Rubber.
Fire-proof (refractory) brick lining protects furnaces, boilers, kilns and other thermal process equipment from sustained high temperature and repeated heat cycling.
We install high-alumina refractory brickwork suited to the operating temperature and thermal-cycling profile of the equipment, using our own fire-resistant brick supply.
Work covers new furnace/kiln linings as well as relining of equipment where the existing refractory has reached end of life.
Industries & Applications
- Furnace and kiln operators
- Boiler and thermal process equipment
- Metal casting and foundry operations
- Chemical process heating equipment
Materials & Lining Systems
- High-alumina refractory bricks
- Refractory mortar matched to service temperature
- Insulating backup lining where specified
Resistance
Chemical
High-alumina refractory brick resists chemical attack from combustion by-products and process fumes typical of thermal equipment.
Temperature
Engineered for sustained high-temperature service and repeated thermal cycling — exact temperature rating depends on the brick grade selected for your equipment.
Abrasion
Good resistance to mechanical wear from charge material and thermal-cycling stress in furnace and kiln environments.
Surface Preparation
- 1Removal of existing refractory lining where relining
- 2Inspection of the shell/structure for damage requiring repair before relining
- 3Layout and setting-out of brick courses to suit furnace or kiln geometry
Installation Steps
- 1Bedding and laying of refractory bricks in matched mortar, course by course
- 2Expansion-joint detailing appropriate to the thermal-cycling profile
- 3Detailing around burners, flues and other penetrations
- 4Controlled curing and initial heat-up (dry-out) sequence before full operating temperature
Inspection & Testing
- Visual inspection of brick coursing and joint quality
- Confirmation of expansion-joint spacing before heat-up
- Supervised dry-out/heat-up to avoid thermal-shock damage to new brickwork
Completion Time & Maintenance
Typically 1–4 weeks depending on furnace/kiln size and lining complexity, plus a supervised heat-up period before full operating temperature.
- Scheduled inspection during planned shutdowns for cracked or spalled brick
- Prompt repair of localised refractory damage to prevent it spreading during the next heat cycle
- Follow the confirmed heat-up/cool-down rate to avoid thermal-shock damage
Frequently Asked Questions
How is fire-proof brick lining different from acid-proof brick lining?
Acid-proof brick lining is built for chemical resistance at ambient-to-moderate temperatures. Fire-proof (refractory) brick lining uses high-alumina brick and refractory mortar engineered specifically for sustained high temperature and thermal cycling in furnaces, kilns and boilers.
Do you supervise the initial heat-up after relining a furnace?
Yes — new or relined refractory brickwork needs a controlled dry-out and heat-up sequence to avoid thermal-shock cracking, and we plan this as part of the project handover.
Can you reline a furnace section without a full shutdown?
It depends on the equipment design — some furnaces allow sectional relining while other sections stay in service, others require a full shutdown. We assess this during project planning.
