Service · Refractory Application
Refractory Application Services for Power Plants, Boilers & Kilns
Castable refractory, gunning spray cement, plastic refractory and brick lining — applied on site by trained crews. 30+ years of pan-India refractory application experience for power, steel, cement and petrochemical industries.
What we apply
All major refractory product families — selected and specified per the operating temperature, atmosphere and abrasion conditions of your equipment.
Castable Refractory Application
Dense castable, low-cement castable (LCC), insulating castable and bottom-ash hopper castable — placed by casting, vibration or pneumatic gunning per equipment design.
Gunning Spray Cement
Pneumatic gunning of refractory mix through a high-pressure nozzle — fastest method for boiler furnace walls, cyclone preheaters and emergency relining work.
Plastic Refractory
Hand-rammed and air-rammed plastic refractory for burner blocks, tap-holes, ladle pour spouts and any complex geometry where casting is impractical.
Refractory Brick Lining
High-alumina, fireclay, magnesite and silica brick lining for kilns, blast-furnace stacks, soaking pits and ladles — bonded with matching mortar grades.
Ceramic Fibre & LRB Insulation
Ceramic blanket, LRB mattress and modular ceramic block installation as backup insulation — reduces shell-temperature and heat loss.
Anchors & Support Systems
MS and SS-304/310 V-anchors, Y-anchors, hex-mesh and stud welding for castable and gunning retention — fabricated and welded per drawing.
Equipment we line
CFBC, AFBC, stoker-fired & HRSG boilers
Furnace walls, bed coils, cyclone separators, ducts and ash hoppers — castable + gunning + ceramic insulation backup.
Rotary kilns & preheater cyclones
Hot-zone brick lining, calciner gunning, cooler grate refractory and tertiary-air duct lining.
Blast furnaces, ladles & tundishes
High-alumina brick lining, slag-line magnesite, ladle bottom castable, monolithic tundish lining.
Incinerators & afterburners
Primary chamber + secondary chamber lining, throat zones, refractory door castings.
Petrochemical reformers & heaters
Tube-supports, header boxes, peephole castings, ceramic fibre back-up insulation.
Power-plant ducts & plenums
Insulating castable, ceramic fibre lining for ID/FD ducts, expansion-joint refractory.
Why operators choose MS Enterprises for refractory application
Trained refractory masons. Our crews are not generic labour. Each supervisor has 10+ years of refractory application experience across CFBC boilers, cement kilns and steel plant equipment. Junior masons train under them for at least two cycles before working independently.
Material + application from one vendor. Coordinating supply and application separately is the #1 source of disputes during shutdowns. We source castables, gunning mix, bricks and ceramic insulation directly from manufacturers and apply them with our own crews — single-point accountability for material quality and workmanship.
Manufacturer-spec procedure adherence. Mixing water content, casting consolidation, gunning rebound rate, curing temperature ramp — every parameter is followed and documented. We hand over batch records, temperature logs and inspection reports for your audit file.
Pan-India mobilization. Active project base in Maharashtra, Chhattisgarh, MP, Odisha, Gujarat, Telangana, Karnataka and Tamil Nadu. Tools, gunning machines and senior supervision deployed from Nagpur HQ.
Refractory application — frequently asked questions
What is refractory application and how is it different from refractory supply?▼
Refractory application is the on-site installation of refractory materials — mixing, casting, gunning, ramming and curing — onto the equipment lining. Supply is delivery of the raw refractory materials. M.S. Enterprises offers both: we supply directly from manufacturers and our trained crews apply on site, eliminating the coordination overhead of working with separate vendors.
Which industries do you serve for refractory application?▼
Power plants (CFBC, AFBC, HRSG and pulverized-coal boilers), steel plants (blast furnaces, ladles, tundishes), cement plants (rotary kilns, preheater cyclones, coolers), petrochemical refineries, sugar and distillery boilers, and paper mill recovery boilers. We have executed projects across Maharashtra, Chhattisgarh, MP, Odisha, Gujarat, Telangana, Karnataka and Tamil Nadu.
What is gunning spray cement application?▼
Gunning spray cement (also called gunning mix or shotcrete) is a refractory material applied pneumatically through a high-pressure nozzle. It is the fastest method to repair worn linings during planned shutdowns — ideal for boiler furnace walls, kiln hot zones and rapid relining without removing the existing structure. We provide both gunning material supply and trained gunning operators.
Do you handle dry-out and curing after application?▼
Yes. Proper dry-out is critical — improper curing causes thermal shock failures within weeks of commissioning. Our scope covers controlled heat-up schedules, burner deployment, temperature logging and post-cure inspection. See our dedicated Dry-Out Services page for details.
How quickly can you mobilize a refractory application crew?▼
Standard mobilization is 7–10 days from PO. For emergency shutdown work in central/western India we can deploy within 48–72 hours subject to crew availability. Pan-India coverage is supported through pre-vetted regional sub-teams.
