Water Model Experiment on Lead Dispersion during the Refining of Free Cutting Steel

Abstract

Water model experiment has been carried out for understanding the dispersion of lead droplets in a steel bath agitated by offset bottom gas injection. Air, water, and fluorinert are used as the model working fluids for argon gas, molten steel, and molten lead, respectively. The dispersion of fluorinert droplets is significantly dependent on the charge position of fluorinert, gas flow rate, and charge time of fluorinert. An optimum condition for the uniform dispersion is determined.
