0.9-1.5mm Silica Nozzle Filling Sand for Steelmaking

Product Description

Silica Based Nozzle Filling Sand

Silica Based Nozzle Filling Sand

SAT-NFC(Nozzle-XS) (Silica Based): SiO2 (%) : 94; Max Service Temp (oC) : 1650; Grain Size (mm) : 0.9-1.5

Stuffing sand is firstly put into the ladle before molten steel is poured. 
When the slide plate located at the nozzle is withdrawn, the stuffing sand will flow out with the flowing molten steel and natural casting is realized. Practice shows that if ladle casting cannot be realized naturally but depends on oxygen consuming, continuous casting heats and production efficiency will be seriously affected. Meanwhile frequent oxygen consumption will reduce the service life of ladle and create a lot of inclusions which influence the steel quality greatly.After dozens of years' researches, we have developed series of products such as silicon stuffing sand, forsterite stuffing sand, high aluminum stuffing sand and chrome stuffing sand.

Chromite Based Nozzle Filling Sand

Our Ladle stuffing sand is made of high quality imported chrome ore, refined quartz sand and high refractoriness material, with good fluidity, fast flow, proper sintered layer thickness, anti-erosion and infiltration of molten steel. Open casting ladle rate reach to 99%, etc. reducing the labor intensity, reducing oxygen drainage, improve the quality of steel products, to ensure the smooth casting process. This chrome stuffing sand is developed through new production process and optimal formula of flow promoting agent and agglutinant inhibitor. It improves the natural casting rate without any contamination to the molten steel. Meanwhile our nozzle fill sands have been developed to meet the needs of steel making facilities worldwide. Each blend is carefully designed to enhance the free flow of steel from the ladle regardless of steelmaking practices. This is achieved through custom blending which affords each customer a product specific to their manufacturing needs.

Type of Nozzle Filling Compound:

1. Chromite Nozzle Filling Compound

2. Silica Nozzle Filling Compound

3. Forsterite Nozzle Filling Compound

4. High Aluminum Nozzle Filling Compound
 

The functions of the tapping ladle refining nozzle filler sand used in steelmaking in steel plants are mainly as follows:

1. Ensure that the sliding nozzle at the bottom of the ladle can be opened smoothly, guide the molten steel to flow out smoothly, and prevent the occurrence of the situation of failed initial casting.
2. Avoid the premature solidification of the molten steel at the nozzle, ensure the continuous casting of the molten steel, and improve the stability and efficiency of the casting.
3. It can prevent the secondary oxidation of the molten steel during the casting process, reduce the generation of inclusions, and thus improve the quality of the steel.
