Abstract

"BRIQUETES DE CARVãO PARA O PROCESSO DE REDUçãO POR FUSãO, E O MéTODO PARA A FABRICAçãO DO MESMO". A presente invenção refere-se a um briquete de carvão para um processo de redução por fusão no qual o carvão e o minério de ferro são carregados em um forno de fusão para produzir um ferro fundido, e um método para produção do briquete de carvão. O briquete de carvão compreende 50% em peso ou menos de pelo menos um entre lama e poeira e o saldo sendo carvão fino, como componentes principais, a lama e a poeira incluindo ferro (Fe) ou compostos de ferro, carbono (C), compostos de Ca e compostos de Mg, e 5-20 partes em peso de um aglutinante, com base de 100 partes em peso dos componentes principais."Coal briquettes for the fusion reduction process and the same method for the manufacture". The present invention relates to a coal briquette for a melt reduction process in which coal and iron ore are loaded into a melting furnace to produce a cast iron, and a method for producing coal briquette. Coal briquette comprises 50% by weight or less of at least one of mud and dust and the balance being fine coal as main components, mud and dust including iron (Fe) or iron, carbon (C) compounds, Ca compounds and Mg compounds, and 5-20 parts by weight of a binder, based on 100 parts by weight of the major components.
