Abstract:Houma Copper Smelter using Top Submerged Lance(TSL) converting system produces blister copper.At the beginning,it used fayalite slag.While in the actual production,the fayalite slag easily leads to slag foam,even leads to serious problems of safe production,because the magnetite levels in the fayalite slag is high with rich oxygen.For effective control of slag foam,the lime modified fayalite slag in the TSL converting furnace is tested.It was proved that the lime modified fayalite slag played a good role at...
