Chrome-Based Ladle Nozzle Filling Compound for Iron and Steel Industry

Product Description

Chrome-based ladle nozzle filling compound sand for iron and steel industry

Product Description

Nozzle Filling Sand plays a pivotal role in steelmaking. Filled in the ladle bottom nozzle, it enables automatic molten steel flow during continuous casting. When steel is poured into the ladle, the sand forms a sintered layer on the surface. Upon opening the slide gate, the unsintered sand falls by gravity, and the steel's hydrostatic pressure breaks the sintered layer, initiating smooth casting without manual intervention. This enhances self-opening rate, ensuring production efficiency and reducing risks. It also prevents nozzle blockage by resisting steel and slag erosion, protecting the slide gate and extending ladle life. Moreover, it avoids steel contamination from oxygen-blowing for manual opening, maintaining steel cleanliness and quality. Its proper sintering property and fluidity are crucial for reliable steel flow control in the steelmaking process.

Application

1. Enable Automatic Molten Steel Discharge
   Filled in ladle bottom nozzles, it forms a sintered layer upon steel pouring. When the slide gate opens, unsintered sand falls by gravity, and steel hydrostatic pressure breaks the layer to initiate flow without manual intervention.
    
2. Improve Ladle Self-Opening Rate
   Optimized granularity and sintering properties enhance self-opening efficiency, reducing production interruptions and steel waste.
    
3. Prevent Nozzle Blockage
   High refractoriness and erosion resistance block slag and debris, maintaining unobstructed steel flow channels.
    
4. Protect Refractory Components
   Mitigates direct erosion to slide gates and nozzles, extending service life of ladle refractories and cutting replacement costs.
    
5. Ensure Steel Quality
   Avoids secondary oxidation and inclusion contamination from manual oxygen-blowing, preserving steel cleanliness.
