Tracking the use of wet spraying for blast furnace lining

　　Wet spraying technology for blast furnace linings, as an advanced repair method, can complete the lining repair of a large blast furnace with a volume of 5500m³ in a very tight timeframe—just 48 hours. This technology not only significantly shortens the downtime for blast furnace maintenance but also effectively improves the blast furnace's operating efficiency, ensuring the continuity and stability of steel production. After repair with wet spraying technology, the service life of the blast furnace lining can be significantly extended to more than 1.5 years; some well-maintained blast furnaces can even exceed this expectation, demonstrating excellent durability and erosion resistance.

　　This blast furnace lining repair model, centered around rapid maintenance, has won full recognition and high praise from the vast majority of blast furnace users at home and abroad, thanks to its convenience and durability. It not only effectively reduces the maintenance cost of the blast furnace but also significantly improves the overall operating efficiency of the blast furnace, injecting strong momentum into the sustainable development of steel enterprises.

　　In the development history of green ironmaking technology in China, wet spraying technology for blast furnace linings undoubtedly plays a crucial role. It not only conforms to the current national development concept of green, low-carbon, and environmental protection but also strongly promotes technological innovation and industrial upgrading in the steel industry. With the continuous promotion and application of this technology, it is believed that more blast furnaces will benefit from this environmentally friendly repair method in the future, jointly promoting the development of China's steel industry towards a greener and more intelligent direction.
