快削鋼精錬時の鉛分散に関する水モデル実験

抄録

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.
