초록

국내 건조 골재로 사용되고 있는 인조 규사는 매년 채취량이 증가하고 있다. 건조 골재로 가공하기 위하여 건조 공정이 필요하며, 이는 골재의 원가 상승과 화석 연료를 이용한 대기 환경오염의 주범이다. 이를 위해 건조 골재에 대한 대체 골재 개발이 매우 시급한 실정이다. 본 연구에서는 제강 환원슬래그의 고효율 급냉 자원순환기술에 대한 특허와 논문을 분석하였다. 분석범위는 1977년~2013년까지의 미국, 유럽연합, 일본, 한국의 등록/공개된 특허와 SCI 논문으로 제한하였다. 특허와 논문은 키워드를 사용하여 수집하였으며, 기술의 정의에 의해 필터링 하였다. 특허와 논문의 동향은 연도, 국가, 기업, 기술 등에 따라 분석하여 고찰하였다.

The artificial dry silica used as dry aggregates in domestic is collected increasing every year. It is required drying process for the production of dry aggregates, therefore, it is main culprit of the cost up of aggregates and air pollution by using fossil fuel for the solution, it is developed alternative aggregates for the replacement of dry aggregates very ungently. In this article, the patents and papers for the recycling technology on the high-efficiency rapid cooling method of ladle furnace slag were collected and analyzed. The open patents of USA (US), European Union (EP), Japan (JP), and Korea (KR) and SCI journals from 1977 to 2013 were investigated. The patents and journals were collected using key-words and filtered by the definition of the technology. The patents and journals were analyzed by the years, countries, companies, and technologies and the technical trends were discussed in this paper.
