Ladle Filler Stuffing Sand
Place of Origin:Henan China (Mainland)
Refractoriness (Degree):1750°< Refractoriness< 2000°
ladle chromite filler stuffing sand
Bulk density (g/cm3):
The stuffing sand is mainly made up of imported high-purity chrome sand . It is suitable for steelmaking processes with long refining times such as LF, VD, and RH. The main component is SiO2 ≥ 40%, refractoriness > 1800, bulk density (t/m3) is 2.3-2.6.
Product advantages: When adding the stuffing sand , the sand blaster is used and stacked into a cone shape to prevent the molten steel from scouring and affecting the self-opening rate. In short-flow steelmaking, it has good fluidity, high refractoriness, large specific gravity, fast flow rate, proper thickness of sintered layer, and resistance to molten steel erosion and penetration.
Function and performance: anti-steel erosion and penetration, ladle self-flowing rate more than 99%, greatly reducing the labor intensity, reducing oxygen drainage, improving the quality of steel products, ensuring the continuous casting process goes smoothly .
1 Feeding sand to ladle before tapping.
2 Can feed by hand or use feeding machine, using sand filling device is more ideal. Quantity is according to the size of well block and nozzle , the sand pile should be formed in a mountain-packed shape 5 to 10 cm higher than the bottom of ladle.
