説明

Since high VM coal is inexpensive and deposits are abundant all over the world, the use of high VM coal is highly desirable in the carbon composite iron ore reduction process. However, when high VM coal is used, deterioration of DRI strength will occur. In order to solve this problem, different carbonization conditions were applied to high VM coal and different agglomeration methods were tested. As a result, when the non-carbonized coal was used and iron ore/coal composite briquettes were made under high pressure, high strength DRI was obtained. By this method, the porosity was effectively reduced in the carbon composite agglomerates, internal heat transfer was improved, and sintering of reduced metal was promoted.
