Abstract (en)
A method for manufacturing coal briquettes charged into a dome part of the melter-gasifier to be rapidly heated in an apparatus for manufacturing molten iron including a melter-gasifier into which reduced irons are charged, and a reducing furnace connected to the melter-gasifier and providing the reduced iron. The method for manufacturing coal briquettes include i) providing fine coal; ii) preparing a mixture by mixing a hardening agent of 1 to 5 parts by weight and a binder of 5 to 15 parts by weight with respect to fine coals of 100 parts by weight; and iii) molding the mixture. In the providing of the fine coal, the fine coals include low-grade coal of more than 0 and 50wt% or less and remaining carbonaceous materials. The low-grade coal has a volatile matter (on a dry basis) of 25wt% to 40wt% and a free swelling index of more than 0 and less than 3.
