Technology of Inducing Dispersed In-situ Phases by Composite Ball Explosion Reaction during IF Steel Production
A novel cleanness steel production technology due to the dispersed in-situ phase induced by the composite ball explosion reaction has been put forward.A composite ball with this function has been designed and the industrial experimental investigations have also been carried out in ANSTEEL.The results indicate that this novel technique is a low-cost and high efficiency cleanness steel production method,which can realize quick slag forming,fast dephosphorization and fine inclusion removal.Temperature drop during transferring is small.The heat-up speed during LF has been increased for more than 2℃/min and the refining period has been shortened for 3~8min.The phosphorous and total oxygen in the as-cast slab can approach to 30 ppm and 6 ppm,respectively after its treatment.
