Steel Ladle
Nano microporous insulation panels have thermal insulation performance that is 3 to 4 times higher than conventional materials and can withstand high temperatures. They are particularly suitable for thermal insulation in steel equipment, helping achieve energy saving and emission reduction.
Thermal insulation materials are a crucial component of steel production equipment and have a significant impact on energy consumption. Nano microporous insulation materials are considered to have the best insulation performance among known high-temperature materials. They are increasingly being adopted in steelmaking equipment, significantly reducing equipment surface temperatures, minimizing heat loss, improving product quality, enhancing production efficiency, and lowering steel production costs.
Introduction to Nano Microporous Insulation Materials
Nano microporous insulation materials offer insulation performance 2–10 times better than traditional insulation materials. They are a new type of material developed based on the principle of microporous insulation. The main component is ultrafine silica powder with particle diameters of 7–20 nm, combined with thermal radiation opacifiers, high-strength ultrafine fibers, and high-temperature shrinkage-resistant materials, and formed through a special pressing process.
The product surface can be covered with fiberglass cloth, aluminum foil, or plastic film. Common forms include rigid panels, blankets, rolls, and blocks. Rigid panels are used for flat furnace walls or those with small curvature; blankets are suitable for equipment with strict space limitations such as ladles; roll-type materials are mainly used in piping systems.
Nano microporous insulation materials have excellent machinability and enhanced strength. They are easy to install and can be conveniently cut and shaped. These materials maintain extremely low thermal conductivity over a wide temperature range. They can withstand instantaneous temperatures up to 1100°C, with a long-term operating temperature of up to 1000°C.

Application of Nano Microporous Insulation Materials in the Steel Industry
1. Application in Ladles
Installation Method:
Clean the inner wall of the ladle, apply a layer of high-temperature adhesive, attach nano microporous insulation blankets, and then sequentially construct the permanent lining and working lining.
Performance Benefits:
Reduces heat loss from the ladle shell
Lowers tapping temperature from the converter
Reduces the heat required for ladle preheating
Decreases shell temperature, improving ladle lifespan and safety
Replaces overly thick insulation bricks, increasing molten steel capacity
Reduces the temperature difference between the hot and cold faces of refractory bricks, extending their service life
Case Study: 130-ton Ladle
Refractory Structure (from outside to inside):
Nano microporous insulation blanket: 7 mm
60% high-alumina brick: 63 mm
Castable: 25 mm
MgO-C brick: 150 mm
Results:
Shell temperature reduced by 80–100°C
Significant reduction in slag adhesion
No need for reheating during continuous casting cycles
Extended service life of surrounding equipment
Increased molten steel capacity
2. Application in Tundish
Installation Method:
Lay a layer of nano microporous insulation boards on the inner wall of the tundish, avoiding anchors, and then install the castable.
Performance Benefits:
Reduces heat loss during continuous casting
Minimizes temperature fluctuations of molten steel
Improves continuous casting quality
3. Application in Torpedo Ladle (Hot Metal Car)
Installation Method:
Lay a layer of nano microporous insulation boards on the inner wall of the torpedo ladle, followed by installation of refractory bricks.
Performance Benefits:
Reduces heat loss during hot metal transportation
Maintains higher temperature of hot metal upon arrival at the converter (temperature drop reduced by ~40°C)
Lowers converter energy consumption
Creates favorable conditions for dephosphorization during transport
4. Application in Water-Cooled Columns of Walking Beam Reheating Furnace
Installation Method:
Wrap two layers of nano microporous insulation boards around the water-cooled pipes, fix them with iron wire, and then apply castable.
Performance Benefits:
Compared with ceramic fiber insulation, heat removed by cooling water is reduced by approximately 24%
With the continuous maturation of application technologies, nano microporous insulation materials are increasingly adopted in steel plants both domestically and internationally. Their effectiveness in energy saving and emission reduction has been widely recognized.
Although the initial investment cost may be higher, the energy savings achieved during steel production far outweigh the upfront cost. These materials enable precise control of heat loss, ensure optimal energy utilization, improve overall efficiency, and minimize environmental impact.
Serious heat loss, fast temperature drop, short refractory lining service life.
