COAL BRIQUETTE, METHOD FOR MANUFACTURING SAME, DEVICE FOR MANUFACTURING SAME, INGOT IRON MANUFACTURING METHOD, AND INGOT IRON MANUFACTURING DEVICE

摘要

Provided are a coal briquette, a method for manufacturing the same, a device for manufacturing the same, an ingot iron manufacturing method, and an ingot iron manufacturing device. The coal briquette is inserted into a domed portion of a melting gas brazier of an ingot iron manufacturing device and is heated rapidly, the ingot 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%.
