초록

The waste casting sands generated from foundry is about 4,000 tons/day and the great part of them is handled by the method of reclamation and just 10% of them is recycled as a sand. This study is to produce the iron lump of high quality material through melting iron particle which is obtained from thewaste casting sands. By using the high frequency inductive melting furnace after separating iron particle from casting sand by collision and vibrating classifier, iron lump is produced from melting iron particles.
The iron lump of iron content of 96.95% is produced from iron particle of 68.05% through this process. It was investigated that the cost of iron lump is four times higher than the one of iron particle and to produce iron lump is worth to 325 won per kg against iron particle with considering the consumed power(electric energy). Therefore, to produce iron lump from waste casting sands is not only to be economical worth but also to strengthen the ground resources system.
