Part Of Elbow & Belly Pipe

The air supply device is another core product of our company. In 2010, the product won the Shijiazhuang High-tech Achievement Landing Award, and in 2012, the blast furnace air supply device project was established as the National Torch Program project. Due to the importance of its use part, the product puts forward higher requirements, in addition to the structure of the product according to the site conditions for reasonable optimization design, the product in the castable requirements are higher, for this we have a professional team of engineers responsible for the production of castable, and each batch of castable are tested for strength and heat resistance. The company took the lead in using the domestic advanced cyclone baking oven to bake the castable, it adopts fully automatic computer temperature control operation, using natural gas as fuel, high baking temperature, full and uniform baking, can completely discharge the crystalline water and free water in the castable, avoid the use of the refractory in the process of high residual moisture and microcracks, and even redness and burn-through, so as to ensure the safety and reliability of our air supply device product performance, the highest point of the surface temperature of the entire air supply device does not exceed 150 °C. At present, our company has obtained 4 patents for air supply device products. Design Pressure: 0.3MPa~0.65MPa Design Temperature: ~1450°C Application: Applied to BF of 450m³~5800m³ blast furnace
