Abstract

결정수를 3% 이상 함유한 게사이트 광석1(철광석 A)을 원료의 일부로 사용하여 원료에 대한 제품의 비율이 좋고, 강도높은 소결광을 제조하는 경우, 제사이트 광성 1을 주원료에 대하여 60%에 배합하고, 게사이트 광석의 1/4의 반광⑵을 가하여 과랍기⑷를 사용하여 혼합 ·유사 과랍화하고, 이들 유사입자를 저결정수광석, 석회석, 규석, 코크스 등의 배합원료⑶와 드럼믹서⑸로 혼합하여 소결원료로 한다.If Gesite Ore 1 (iron ore A) containing 3% or more of crystal water is used as a part of the raw material, the ratio of the product to the raw material is good and the sintered ore with high intensity is produced. The mixture is mixed with a semi-glossy 게 of Gesite ore and mixed with a similar rapeseed group, and the similar particles are mixed with raw materials such as low crystal ore, limestone, silica, and coke and drum mixer. Mix with IX to make sintered raw material.
