Abstract

Abstract

The influence of EAF dust and coal amounts added into slag as well as temperature on the slag foaming height had been investigated in laboratory. The results show that the maximum slag foaming height increases, with the increase of EAF dust and coal amounts added as well as temperature. The reduction and evaporation rate of ZnO speeds up with the increase of temperature during slag foaming. The evaporation rate of ZnO is more than 97% in 6 min. Pb in slag is less than 0.02% in 3 min. Temperature seems to have no clear affect on the evaporation rate of Pb in slag.
