发明名称 METHOD FOR RECYCLING ELECTRIC FURNACE DUST
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a method for recycling electric furnace dust, in which the electric furnace dust is recycled into the electric furnace by handling the electric furnace dust with a lifting-magnet crane while maximizing a recycling ratio of a the electric furnace dust into the electric furnace. <P>SOLUTION: In the method for recycling the electric furnace dust, the dust generated in the electric furnace (the electric furnace dust) and granular irons (the granular iron recovered from the slag) wherein the steel-making slag is crushed and sorted by a magnetic force to recover, are mixed and thereafter, charged into the electric furnace. The ratio of the granular iron recovered from the slag, is set to be 5-50 mass% based on the total content of the electric furnace dust and the granular iron recovered from the slag. As the result of mixing the granular iron recovered from the slag, even in the case of maximizing the recycling ratio of the electric furnace dust, the dust can be handled with the lifting magnetic crane. <P>COPYRIGHT: (C)2011,JPO&INPIT</p>
