Technical background

Al2O3-C refractory ramming materials are widely used in high-temperature industrial fields, such as high-temperature furnace linings in steel, glass and other industries. Traditional Al2O3-C refractory ramming materials have high fire resistance, but under high temperature and high pressure conditions, the mechanical strength and durability of the material often cannot meet higher requirements. In order to improve its physical properties and extend its service life, hydrophilic treatment technology came into being.

Hydrophilic treatment principle

Hydrophilic treatment technology improves the wettability and adhesion of the ramming material by introducing specific hydrophilic additives into the ramming material. These additives can form a high-strength network structure under high temperature conditions, significantly improving the thermal shock resistance and overall strength of the material. The hydrophilic treated ramming material can better maintain its shape and performance under high temperature conditions, reduce the thermal expansion coefficient and reduce the generation of cracks.

Practical application cases

After a large steel company introduced hydrophilic treated Al2O3-C refractory ramming material, the service life of its high-temperature furnace lining was increased by about 30%, saving about 5 million yuan in maintenance costs in 2022 alone. The advantages don't stop there. The convenience of repair and replacement of hydrophilic treated materials is also greatly improved, reducing the economic losses caused by production shutdowns.

data analysis

Research shows that the compressive strength of ramming materials after hydrophilic treatment is increased by 25%, the thermal shock resistance is increased by 40%, and the high-temperature oxidation resistance is increased by 35%. These data demonstrate the effectiveness and advantages of hydrophilic treatment technology.

market impact

The application of hydrophilic treatment technology not only improves the performance of Al2O3-C refractory ramming materials, but also significantly promotes the development of related industries. As the market demand for high-performance refractory materials continues to grow, this innovative technology is expected to occupy a larger market share in the next few years and bring huge economic benefits to related companies.

In the global refractory materials market, hydrophilic treatment technology may drive a technological revolution and elevate the performance of traditional refractory materials to new heights. Forecasts show that by 2025, the market share of refractory materials using hydrophilic treatment technology will grow to more than 15% of the total market.

In summary, the application of hydrophilic treatment technology in Al2O3-C refractory ramming materials will provide better solutions for high-temperature industries and further enhance the sustainable development capabilities of the industry.
