Successful applications of high alumina refractory bricks in the steel industry
In the steel industry, high alumina refractory bricks have become an indispensable part of many high-temperature equipments due to their excellent refractory performance and erosion resistance. The following is a real case of successful application of high alumina refractory bricks in the steel industry.
Background
In order to improve the productivity and stability of the blast furnace, a large steel enterprise decided to upgrade the lining of its blast furnace. During the renovation process, the company chose high alumina refractory bricks with high refractoriness and good slag resistance as the main material for the furnace lining. This decision was based on the excellent performance of high alumina refractory bricks in the iron and steel smelting process, as well as their extensive experience in high temperature equipment such as blast furnaces.
Application process
1、Material selection: The enterprise selected suitable high alumina refractory bricks according to the specific working environment and requirements of the blast furnace. These high alumina refractory bricks have a high content of aluminium trioxide of more than 75%, which ensures their excellent refractoriness and erosion resistance.
2、Design and construction: The enterprise hired professional refractory engineers to design the blast furnace lining and carried out fine construction according to the design drawings. During the construction process, the engineers strictly control the masonry quality of high alumina refractory bricks and gap treatment to ensure the integrity and stability of the furnace lining.
3、Performance test: After the upgrading and transformation of the blast furnace lining was completed, the enterprise carried out a comprehensive performance test. The test results show that the addition of high alumina refractory bricks significantly improves the refractory performance of the blast furnace, enabling it to operate stably under high temperature and slag erosion.
Application effects
1、 Improved productivity: The refractory performance of the blast furnace has been significantly improved due to the excellent performance of the high alumina refractory bricks. This enables the blast furnace to operate stably at higher temperatures, thus improving production efficiency.
2、To extend the service life: high alumina refractory bricks of erosion resistance so that it can be in the harsh working environment for a long time to keep intact. This greatly extends the service life of the blast furnace lining, reducing the frequency of repair and replacement.
3、 Reduce costs: due to the use of high alumina refractory bricks, the blast furnace maintenance costs have been effectively controlled. At the same time, due to the improvement of production efficiency, the overall operating costs of the enterprise has also been reduced.
4、 Improve product quality: the use of high alumina refractory bricks to ensure the stable operation of the blast furnace, thereby improving the quality and stability of steel products. This makes the enterprise more advantageous in the market competition.
Conclusion
This case shows the successful application of high alumina refractory bricks in the steel industry. By choosing the right high alumina refractory bricks, carrying out detailed construction and performance tests, the company has successfully improved the productivity and stability of the blast furnace. This not only reduces the operating costs of the enterprise, but also improves the quality and market competitiveness of the products. The wide application of high alumina refractory bricks in the iron and steel industry has a broad prospect and will continue to make important contributions to the development of the iron and steel industry in the future.
