Abstract
Способ окомкования агломерационной шихты, состоящей из измельченных руд или их концентратов, флюсующих и других добавок, а также твердого топлива, включающий получение двухслойных гранул путем подачи более 50% топлива в конце окомкования, отличающийся тем, что во внешний слой гранул при окомковании вводят буроугольный полукокс, обладающий пониженной температурой воспламенения и повышенной реакционной способностью, оптимальное количество которого должно составлять от 40 до 50% от общего расхода твердого топлива в процессе агломерации. A method of pelletizing an agglomeration charge consisting of crushed ores or their concentrates, fluxing and other additives, as well as solid fuel, comprising producing two-layer pellets by supplying more than 50% of fuel at the end of pelletizing, characterized in that brown pellet semi-coke is introduced into the outer layer of pellets having a low flash point and high reactivity, the optimal amount of which should be from 40 to 50% of the total consumption of solid fuel in the process of agglomeration.
