Abstract
1. Способ производства агломерата для доменной плавки, спекаемого из шихты, состоящей из железосодержащих компонентов, флюса и топлива, включающий ее подготовку путем дозирования, смешивания и окомкования, последующее спекание и проплавку полученного агломерата, отличающийся тем, что в процессе подготовки в качестве одного из железосодержащих компонентов формируют смесь из шламовой окалины, содержащей шламы и окалину, в том числе замасленную, с мелкофракционной добавкой растительного происхождения в массовом отношении добавки к шламовой окалине в пределах 0,01-0,07 дифференцированно для производства агломерата различной основности. ! 2. Способ по п.1, отличающийся тем, что при производстве агломерата в интервалах основности CaO/SiO2 1,10-1,44 ед. и 1,45-1,90 ед. массовое отношение добавки к шламовой окалине в формируемой смеси устанавливают предпочтительно в пределах соответственно 0,01-0,05 и 0,01-0,07. !3. Способ по п.1, отличающийся тем, что в качестве добавки растительного происхождения используют древесные опилки и/или торф. 1. The method of production of sinter for blast furnace sintering from a mixture consisting of iron-containing components, flux and fuel, including its preparation by dosing, mixing and pelletizing, subsequent sintering and melting of the obtained sinter, characterized in that during the preparation as one of the iron-containing components form a mixture of sludge scale containing sludge and scale, including oily, with a fine-grained additive of plant origin in a mass ratio of the additive to sludge oh oxide scale in the range 0.01-0.07 for the production of differentiated agglomerate of different basicity. ! 2. The method according to claim 1, characterized in that in the production of agglomerate in the intervals of basicity CaO / SiO2 1.10-1.44 units. and 1.45-1.90 units. the weight ratio of the additive to slurry scale in the mixture to be formed is preferably set in the range of 0.01-0.05 and 0.01-0.07, respectively. ! 3. The method according to claim 1, characterized in that wood sawdust and / or peat are used as an additive of plant origin.
