Provided are coal briquettes, a method and an apparatus for manufacturing the same, and a method and an apparatus for manufacturing molten iron. The coal briquettes are inserted into a domed portion of a melting gas brazier of a molten iron manufacturing device and is heated rapidly, the molten iron manufacturing device comprising: i) a melting gas brazier, into which reduced iron is inserted; and ii) a reducing furnace, which is connected to the melting gas brazier, and which provides reduced iron. A coal briquette manufacturing method comprises the steps of: i) providing pulverized coal; ii) mixing the pulverized coal with a powder-type cellulose ether compound, thereby providing a mixture; iii) adding water to the mixture and mixing the same; and iv) providing a coal briquette by molding the mixture. In the step of providing a coal briquette, the amount of cellulose ether compound included in the coal briquette is 0.7wt% to 2.0wt%. |
