COKE AND METHOD FOR PRODUCING SAME
This coke is characterized by being obtained by mixing 2 to 8% ashless coal with coal and carbonizing the mixture thereby produced, and is further characterized in that the maximum fluidity (MF) value (log (ddpm)) of the mixture of coal and ashless coal is 1.8 to 3.0. By keeping the additive rate of...

Summary: | This coke is characterized by being obtained by mixing 2 to 8% ashless coal with coal and carbonizing the mixture thereby produced, and is further characterized in that the maximum fluidity (MF) value (log (ddpm)) of the mixture of coal and ashless coal is 1.8 to 3.0. By keeping the additive rate of the ashless coal at 8% or less while compensating for the caking property using the ashless coal, and ensuring the overall fluidity using the coal, volume destruction and inhibition of the growth of crystals due to the ashless coal is prevented, thereby allowing coke with large particles to be produced.
Le coke de l'invention est caractéristique en ce qu'il est constitué par mélange et carbonisation de 2 à 8% d'un charbon sans cendres dans un charbon, et la valeur du degré de fluidité maximum (MF) (log(ddpm)) du mélange charbon et charbon sans cendres, est comprise entre 1,8 et 3,0. Un coke à gros grains est produit tout en compensant ses propriétés d'agglutination par le charbon sans cendre dont le taux d'adjonction est limité à 8% au plus, et en garantissant la fluidité de l'ensemble par le charbon, permettant ainsi d'empêcher une fragmentation volumique par le charbon sans cendres et une inhibition du développement de cristaux. |
