What Is Tempseal?

TempSEAL forms an enduring, heat-resistant seal or protective coating on surfaces that are exposed to very high temperatures and thermal cycling. Where ordinary sealants fail — cracking, oxidizing, or spalling away under repeated heating and cooling — TempSEAL remains stable and adherent. This stability helps keep refractory bricks, metalwork, and junctions intact and reduces leakage of hot gases or molten metal residues. The result is safer operations, lower energy use, and fewer unplanned shutdowns. TempSEAL minimizes convective and conductive heat loss from furnaces and heat-treatment equipment. Less heat lost means better fuel efficiency and more consistent process temperatures. TempSEAL is a advanced heat insulation coating with high-temperature sealing and protective solution developed for furnaces, ladles, ducts, expansion joints, and refractory interfaces encountered in iron and steel processing. It’s not just a filler or a paint — it’s a performance product designed to protect equipment, reduce energy loss, and extend maintenance intervals in high-heat environments.

Key Features of Tempseal:-

  1. Thermal protection and reduced heat loss:-  By sealing joints, gaps, and damaged refractory areas, TempSEAL minimizes convective and conductive heat loss from furnaces and heat-treatment equipment. Less heat lost means better fuel efficiency and more consistent process temperatures.
  2. Mechanical and thermal shock resistance:-  Iron and steel processes involve rapid temperature changes. TempSEAL is formulated to tolerate thermal cycling without cracking or detaching, reducing the need for frequent patch repairs.
  3. Improved refractory life:-  Thermal protection and reduced heat loss: By sealing joints, gaps, and damaged refractory areas, TempSEAL minimizes convective and conductive heat loss from furnaces and heat-treatment equipment. Less heat lost means better fuel efficiency and more consistent process temperatures.
  4. Mechanical and thermal shock resistance:-  Iron and steel processes involve rapid temperature changes. TempSEAL is formulated to tolerate thermal cycling without cracking or detaching, reducing the need for frequent patch repairs.
  5. Improved refractory life:-  Small leaks or cracks in refractory linings accelerate wear. By sealing these defects, TempSEAL prevents flame impingement and hot-spot formation, slowing refractory erosion and extending service life.
  6. Reduced downtime and maintenance costs:-  Faster field application and long-lasting performance translate to fewer shutdowns for repairs. That lowers maintenance costs and increases plant availability. Plication and long-lasting performance translate to fewer shutdowns for repairs. That lowers maintenance costs and increases plant availability. 

Why TempSEAL is Essential For iron and steel processing?

Iron and steel production is uniquely demanding. Furnaces, reheating chambers, ladles, and torpedo cars operate at very high temperatures and face direct contact with slags, molten metal, and aggressive atmospheres. Here’s the reasons Why TempSEAL is Essential For iron and steel processing?

Furnace efficiency and temperature control:-

Maintaining uniform temperatures in blast furnaces, electric arc furnaces, and reheating furnaces is crucial for product quality and energy consumption. Leaks and damaged brickwork allow heat to escape and cause uneven heating. TempSEAL’s sealing ability helps restore thermal continuity so process temperatures remain stable and predictable.

Protection against slag and molten metal attack:-

Slag splashes and molten-metal contact can rapidly erode unprotected areas. Applying TempSEAL to vulnerable zones reduces direct contact and provides a sacrificial protective layer that delays the onset of severe damage.

Managing expansion joints and moving parts:-

Expansion joints and ductwork in steel plants must accommodate movement while preventing gas leakage. TempSEAL’s flexibility and best thermal insulation coating with high-temperature resilience make it ideal for these dynamic interfaces, sealing gaps without compromising movement. 

Extending refractory life and lowering total cost of ownership:-

Frequent refractory repairs not only cost money but also require downtime that disrupts production. TempSEAL contributes to longer refractory intervals, meaning the plant spends less on materials, labour, and lost production time — improving the plant’s total cost of ownership.

Rapid field application for urgent repairs:-

Emergency repairs in a steel plant demand quick, reliable solutions. TempSEAL can be applied in situ to patch leaks and cracks rapidly, allowing operations to continue or be safely brought to a planned stop for full repairs.
