COAL BRIQUETTE MANUFACTURING METHOD AND COAL BRIQUETTE MANUFACTURING APPARATUS

摘要

Provided are a coal briquette manufacturing method, which separately crushes coals by coal type so as to achieve excellent cold strength and hot strength, and a coal briquette manufacturing apparatus. The coal briquette manufacturing method is applied for insertion into a dome portion of a melting gas furnace so as to rapid heat in an ingot iron manufacturing device including: i) the melting gas furnace into which reduced iron is inserted; and ii) a reducing furnace that is connected to the melting gas furnace and provides the reduced iron. The coal briquette manufacturing method includes the steps of: i) providing a plurality of types of coals; ii) individually storing the respective pieces of the plurality of types of coals; iii) providing powdered coal by individually crushing each one of the plurality of types of coals; iv) providing a mixture by mixing the powdered coal, a curing agent, and a binder; and v) providing a coal briquette by molding the mixture.
