滲鋁塗層通氣管 |
通氣管由五層組成。核心是高質量的低碳鋼,低碳鋼的內、外表面均經過高溫熱化處理,其中鋁擴散到鋼的表面。然後將熱化管的內部和外部塗上一層耐火材料,該材料耐高溫並降低通氣管的熔化速度。簡而言之,滲鋁處理和陶瓷塗層技術使通氣管在工業應用中具有更長的使用壽命。 |

Applications
- Blowing oxygen, nitrogen and hydrogen into electric arc furnace.
- Injecting carbon, lime powder, and other materials for steelmaking.
- Injecting flux granules for degassing in aluminum melting furnaces
- Cleaning ladle or tundish under high temperature.
- Removal of slag on hearth which produced from manufacturing process.
- Removing slag which adhered to the tapping notch of converters or ladles.
- Resistance of oxidation, abrasion, carburization and vulcanization while producing.

Advantages
- Coating with refractory and calorized substance provides longer life compared MS.
- Multiple applications and longer life which means lower cost.
- Resistance of oxidation, abrasion, and carburization.
- Resistance against erosion or corrosion by molten metal as well as nonmetal substances.
- Prevent from stress corrosion cracking.
- The application raises the production capacity of an electric arc furnace.
