By applying a coating of Rice Husk Ash Powder onto the molten metal, it forms a thick layer of insulation (approximately 1 to 2 inches thick), which effectively retains heat and minimizes radiation heat losses. This insulation significantly reduces temperature drop in the tundish and ladle, mitigating the risk of breakdown in the caster caused by temperature loss.
Apart from its insulation properties, Rice Husk Ash Powder offers other notable advantages. It possesses self-spreading characteristics, ensuring even distribution over the molten metal without forming uneven heaps. This feature enhances metal insulation and contributes to energy savings.
Moreover, the utilization of Rice Husk Ash Powder can diminish the formation of skull, which refers to the solidified layer that develops on the inner surface of the ladle or tundish. By minimizing skull formation, the steelmaking operations become more streamlined and manageable.
Another benefit of employing Rice Husk Ash Powder is its ability to prevent re-oxidation of the metal. By acting as a protective barrier, it safeguards the integrity of the metal and prevents unwanted reactions with oxygen that could lead to impurities or quality issues.
Overall, the application of Rice Husk Ash Powder as an insulating powder in the ladle and tundish during steelmaking facilitates the maintenance of molten metal temperature, enhances energy efficiency, reduces skull formation, and prevents re-oxidation, ensuring the integrity and quality of the metal.
