Iron And Steel Applications
Microporous thermal insulation can deliver significant benefits in terms of Environmental, Economic, Social and Operational impacts in applications in the iron and steel sectors.
Significant energy savings can be achieved, at the same time contributing to a safer workplace, cooler ambients, with reduced maintenance, and providing operational efficiencies.
In molten‑metal processing environments, thermal management systems must maintain strict performance parameters under extreme operating conditions.
Siltherm’s microporous insulation technologies are engineered to deliver highly efficient heat‑flux reduction, improved temperature stability, and enhanced refractory support across critical iron and steel processes.
By minimising conductive and radiant heat losses within ladles, tundishes, blast‑furnace‑adjacent structures, tuyere stocks, and electric arc furnace (EAF) shells, these advanced materials enable reduced preheat requirements, decreased thermal loading on steel casings, and extended component service life. The resulting improvements in energy efficiency, thermal uniformity, and operational safety underscore the suitability of Siltherm’s high‑performance insulation systems for demanding high‑temperature metallurgical applications.
Key applications and benefits for Iron and Steel Processes
Transfer and Process Ladles, Torpedo Ladles
Product:
Siltherm Aluflex >
BENEFITS:
Enhanced productivity, reduced downtime, better temperature control, increased molten metal capacity, lower heat loss, and improved safety.
Siltherm AluFlex introduced as a high performance insulation “back up insulation” in the ladle, tundish, and transport ladles can offer the following benefits due to the superior insulation properties of Siltherm microporous insulation :
Siltherm AluFlex can be supplied in a wide variety of sizes to suit the geometry of the ladle or tundish, in some cases pre curved panels can be supplied to suit the barrel geometry, providing easy installation and avoid unnecessary on site cutting.
Tundishes
Siltherm’s range of microporous insulation solutions are performance driven with rigid and flexible attributes that can be utilised collectively to create complete installation and effective results.
BENEFITS:
Electric Arc Furnace (EAF)
Products:
Siltherm Board >
Siltherm AluFlex >
The introduction of Siltherm Microporous insulation can be deployed as a high performance thermal insulation “back up” insulation behind the refractories against the furnace shell can result in much cooler shell temperatures, cooler ambient temperatures, and a significant reductions in the amount of energy required per tonne of hot metal produced.
Benefits:
Board or Panel can be supplied as pre cut shapes to fit the overall size and geometry of the furnace shell to provide easy installation and avoiding the need for onsite cutting.
Tuyere Stocks
Siltherm microporous insulation supplied as a high performance insulation, customised to fit the geometry inside the Tuyere Stocks can deliver significant benefits in the operational efficiency.
So called “low energy Tuyere Stocks” have a high performance insulation between the casting shell and the pre cast refractory in the Tyuere Stock. Thermal FEM calculations have shown that hot blast thermal energy losses can reduced significantly, in some cases by up to 50%.
This can prolong the life time of the equipment, and deliver reductions in the coke per tonne of hot metal produced.
Benefits include:
Heat Treatment and Forging Furnaces
Products:
Siltherm Board >
Siltherm Panel >
Benefits:
Reduced energy costs, improved heat containment, optimised furnace design, and lower CO2 emissions.
Walking Beams and Skid Pipes
Products:
Siltherm Customised Solutions >
Benefits:
Reduced heat loss, extended equipment lifetime, significant energy savings, innovative refractory hybrid systems, and minimal downtime.
