volatilization of zinc and lead%stainless steel making dust%reduction%recycling
The volatilization of zinc and lead from the stainless steel making dust pellets in the direct recycling procedure was conducted by using a thermo-gravimetric analyzer and a Tamman furnace in the nitrogen atmosphere respectively. The results show that the temperature has a significant effect on the volatilization rates of zinc and lead,and the carbon content in the pellets has no effect on the volatilization process. The volatilization of zinc is controlled by the chemical reaction between zinc oxide and carbon monoxide, while the volatilization of lead is controlled by the evaporation front liquid phase to the atmosphere. The volatilization of zinc and lead mainly happen at about 1 000 ℃according to non-isothermal experiment.
