Description

용선탈규제 조성물Charter Deregulation Composition

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 백운석첨가에 따른 탈규산소 효율 및 구리회수율의 변화(봉사함량 없는 경우)를 나타내는 그래프.1 is a graph showing the change in deoxygenation efficiency and copper recovery rate (when there is no service content) according to dolomite addition.

제2도는 봉사첨가에 따른 탈규산소효율 및 구회수율의 변화를 나타내는 그래프이다.2 is a graph showing changes in deoxygenation efficiency and recovery yield according to service addition.
