Abstract
1. Способ эксплуатации доменной печи, использующий углеродсодержащие необожженные окатыши, в котором сверху доменной печи поочередно слоями загружают железосодержащий материал и кокс, при этом упомянутый способ отличается ! (i) предварительным перемешиванием углеродсодержащих необожженных окатышей и обожженных окатышей и загрузкой смеси упомянутых углеродсодержащих необожженных окатышей и упомянутых обожженных окатышей для замены части упомянутого слоя железосодержащего материала, и ! (ii) регулированием соотношения в смеси между упомянутыми углеродсодержащими необожженными окатышами и упомянутыми обожженными окатышами таким образом, чтобы соотношение R (кг/тн продукта)/P (кг/тн продукта) между удельным расходованием R упомянутых углеродсодержащих необожженных окатышей (кг/тн продукта) и удельным расходованием Р упомянутых обожженных окатышей (кг/тн продукта) становилось бы равным величине в диапазоне от 0,09 до 0,31. ! 2. Способ эксплуатации доменной печи при использовании углеродсодержащих необожженных окатышей по п.1, отличающийся тем, что упомянутое удельное расходование Р обожженных окатышей находится в диапазоне от 150 кг/тн продукта до 650 кг/тн продукта. 1. A method of operating a blast furnace using carbon-containing raw pellets, in which iron-containing material and coke are alternately loaded on top of the blast furnace in layers, and the method is different! (i) premixing the carbonaceous green pellets and calcined pellets and charging a mixture of said carbonaceous green pellets and said calcined pellets to replace a portion of said layer of iron-containing material, and! (ii) adjusting the mixing ratio between said carbonaceous green pellets and said calcined pellets so that the ratio R (kg / ton of product) / P (kg / ton of product) between the specific consumption R of said carbonaceous green pellets (kg / ton of product) and the specific consumption P of said calcined pellets (kg / ton of product) would become equal to a value in the range from 0.09 to 0.31. ! 2. A method of operating a blast furnace using carbon-containing raw pellets according to claim 1, characterized in that said specific consumption P of fired pellets is in the range from 150 kg / ton of product to 650 kg / ton of product.
