In the metallurgical industry, refractory insulation materials play an important role. They not only ensure the safety and stability of the hot working environment, but also improve production efficiency and reduce energy consumption. As a leader in this field, Lucheng energy-saving new materials have shown a wide range of application value in metallurgical kilns with their excellent refractory insulation materials.
1.The harsh requirements of metallurgical kilns
Metallurgical kilns, such as blast furnaces and converters, have extremely harsh working environments and need to withstand multiple tests such as high temperature, erosion, and corrosion. Conventional refractories often have a short lifespan and frequent maintenance under these extreme conditions, resulting in higher production costs. Therefore, the selection of high-performance refractory insulation materials is the key to improving the efficiency and service life of the kiln.
2.The application advantages of Lucheng energy-saving new materials
The amorphous refractories introduced by Lucheng Energy-saving New Materials have been widely used in metallurgical kilns with their unique properties. We have studied the dosage formulations and selection strategies of various steel fibers, which have the following significant advantages:
High refractoriness: The refractory degree of amorphous refractories can reach more than 1700 degrees, which meets the strict requirements of metallurgical kilns for high-temperature environments. This high resistance allows the material to maintain stable structural strength even under extreme conditions.
Energy saving: Compared with traditional shaped refractories, unshaped refractories eliminate the firing process and greatly reduce energy consumption. It is estimated that its energy consumption is 1.5~2.0 times lower than that of traditional refractory bricks on average, achieving significant economy.
Easy to construct: amorphous refractory materials have strong plasticity and can be prefabricated into products of various complex shapes, which is convenient for the mechanization of furnace construction. This not only simplifies the construction process, but also improves construction efficiency.
Improve service life: due to the good integrity of the amorphous refractory material, the sealing performance of the high-temperature furnace is also better than that of the traditional refractory bricks, thereby prolonging the service life of the high-temperature kiln, which can generally be increased by 30%~150% compared with the traditional refractory bricks.
3. Specific application cases
In the application scenario of amorphous refractories, we have studied the addition formulations and selection technology strategies of a variety of steel fibers, so as to determine the better life and better thermal conductivity and thermal insulation performance of the lining.
Blast furnace: Modern blast furnaces mainly use resin-bonded aluminum-carbon unburned bricks for masonry, while the amorphous refractories provided by Lucheng Energy-saving New Materials, such as Al₂O₃-SiC-C (ASC) materials, are ideal for blast furnace lining due to their excellent corrosion resistance and high temperature stability.
Ladle: With the increase of tapping temperature and the extension of molten steel retention time, the refractory materials for ladle have gradually shifted from shaped materials to unshaped materials. The Al₂O₃-spinel casable provided by Lucheng Energy-saving New Materials has excellent corrosion resistance and high temperature stability, which can significantly extend the service life of the ladle.
Heating furnace: The heating furnace is used for heating billets at high temperatures, and the maximum temperature can reach about 1300 °C. The castables or plastics provided by Lucheng energy-saving new materials can meet the needs of refractory insulation of the roof and lining of the heating furnace, improve the heating efficiency and reduce energy consumption.
