Microporous insulation panels represent a cutting-edge solution for the steel industry, offering exceptional thermal insulation performance based on microporous technology. Composed primarily of 7-12 nanometer silica, these panels form countless nano-scale pores that, along with highly effective infrared reflective materials, suppress heat transfer through conduction, convection, and radiation. With a thermal conductivity lower than still air, microporous panels outperform traditional materials by 3-6 times. This makes them one of the most efficient high-temperature insulation materials available today. Available in flat boards, rolls, blocks, and flexible mats, they are suitable for a variety of applications, including furnace walls and pipe systems in steel plants. Their reduced thickness allows for optimized space, lower energy costs, and improved equipment efficiency.
Ladle
Usage:
Clean the inner wall of the ladle and apply a layer of adhesive. First, apply the MIP-950 insulation panel, followed by the installation of the permanent lining and working lining.
Performance Benefits:
1. Reduces heat loss from the ladle shell.
2. Lowers the steel tapping temperature from the converter.
3. Reduces the heat required for ladle preheating.
4. Decreases ladle shell temperature, extending the ladle’s lifespan and improving safety.
5. Replaces excessively thick insulating bricks, increasing the molten steel volume.
6. Reduces the thermal stress on refractory bricks, extending their lifespan.
7. Lowers permanent lining material consumption, reduces ladle weight, eases crane load, and enhances safety.
Tundish
Usage:
Apply a layer of insulation board (5-10mm) on the inner side of the tundish wall, avoiding the steel studs. Then, install the castable refractory.
Performance Benefits:
Reduces heat loss during continuous casting, minimizes molten steel temperature fluctuations, and improves the quality of the continuous casting process.
Torpedo Ladle
Usage:
Apply a layer of insulation board (5-10mm) to the inner side of the torpedo ladle shell, followed by the installation of refractory bricks.
Performance Benefits:
Reduces heat loss during the transportation of molten iron and increases the temperature of the molten iron upon reaching the converter (typically by around 40°C). Lowers converter energy consumption and facilitates desulfurization treatment during torpedo ladle transport.
Hot Blast Pipes
Usage:
Install multiple layers of roll-type insulation material inside the pipe, followed by the installation of refractory bricks or castables.
Performance Benefits:
Reduces heat loss, increases the temperature of the hot air entering the blast furnace, and improves the efficiency of the hot blast stove.
RH Degassing Unit
Usage:
Apply microporous insulation boards (5-10mm) to the inner side of the furnace wall, followed by the installation of castables.
Performance Benefits:
Reduces heat loss during the molten steel circulation process.
