고주파 유도로를 이용한 산업 폐기물의 용융처리
Treatment of Industrial Wastes by Melting Using H.F. Induction Furnace
초록
고주파 유도로에서 철캔, 석회석 슬러지, 폐줌루사, 석탄회, 그리고 폐유리병을 용융하여 철과 슬랙을 얻고 그 특성을 연구하였다. 직교 배열표를 이용하여 각 폐기물의 장입비가 최종 용융물의 물성에 미치는 영향을 조사하였다. 염기도 1.2에서
Iron and slag were prepared by melting mixed industrial wastes in an induction furnace. The wastes were steel can, limestone sludge, waste foundry sand, coal fly ash, and glasses. The effects of their mixing ratio on the charactenstics of the meltcd slag were investigated. The wastes were melted to slag under the constant basicity of 1.2. It was found that the major phases of the slag were P-C,S and C,AS and then ratio was determined by the mixing ratio af waste materials. The recovery of iron was about 93-95%. The feasibility of using the slag as the aggregate was confirmed by thc elution and campression tests.
