Seamless calcium wire should pay attention to the feeding speed and position during operation
The application of seamless calcium wire in the steelmaking process is crucial, and in operation, feeding speed and position are two important factors that need to be paid attention to, which directly affect the effectiveness of calcium wire use and the quality of the final product.
Feeding speed:
The feeding speed should not be too fast, otherwise it will cause the locally generated calcium vapor to be directly evaporated into the air before it can dissolve, resulting in waste and reduced calcium absorption rate.
Similarly, the wire feeding speed should not be too slow, as a slow speed may lead to excessive concentration of calcium wire dissolution in the molten steel, resulting in excessive stirring of the steel and affecting its stability.
The optimal feeding speed should be determined based on actual conditions and experience, and it is usually necessary to ensure that the calcium wire can dissolve uniformly and continuously in the molten steel.
Feeding position:
The selection of feeding position should consider the fluidity of molten steel and the dissolution of calcium wire. The ideal feeding position should allow the calcium wire to fully come into contact with the molten steel, while avoiding the premature generation and volatilization of calcium vapor on the surface of the molten steel.
The feeding point of calcium wire is usually selected at the center of the descending flow of molten steel, which can promote the uniform dissolution of calcium wire by utilizing the flow of molten steel itself, while prolonging the residence time of calcium in molten steel and improving its absorption rate.
During the wire feeding process, calcium wire should be avoided from coming into contact with air to prevent oxidation and other unnecessary chemical reactions.
Reasonable feeding speed and position can improve the absorption efficiency of calcium, ensure the quality and stability of molten steel, and thus improve the performance of the final product. Therefore, in the operation of seamless calcium production lines, these two factors must be given sufficient attention and finely regulated.
