크롬광석펠릿의 원료배합방법Raw material mixing method of chrome ore pellet

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

제1도는 본 발명법 및 비교법에 의해 제조된 예비환원 크롬광석 펠릿의 금속화율을 나타내는 그래프.1 is a graph showing the metallization rate of pre-reduced chrome ore pellets prepared by the present invention method and comparative method.

Claims (1)

예비환원 크롬광석을 제조하기 위하여 크롬광석, 점결제 및 코크스등의 원료를 배합하는 방법에 있어서, 배합원료중의 CaO 양이 0.5-4 중량%가 되도록 상기 배합원료 중에 시멘트류를 첨가하여 원료를 배합하는 것을 특징으로 하는 크롬광석 펠릿의 원료배합방법.In the method of blending raw materials such as chrome ore, caking additives and coke to prepare pre-reduced chromium ore, cement is added to the blended raw material so that the amount of CaO in the blended raw material is 0.5-4% by weight. A raw material mixing method of chromium ore pellets, characterized in that the compounding. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
