Prediction of Zinc and Lead Behavior During Steel Electric Smelting

Аннотация

The balance of zinc and lead is calculated during steel smelting in an electric arc furnace (EAF). It is shown that the main proportion of zinc and lead is removed from metal during charge melting in an EAF, and the remaining amount evaporates during steel degassing. With an increase in the proportion of galvanized steel in a charge, dust formation and zinc and lead contents in EAF discharges increase considerably. In order to determine a strategy for treating zinc-containing dust, it is necessary to monitor its content in all production stages.
