Claims (3)

1. Способ создания защитного гарнисажа на футеровке горна доменной печи, включающий загрузку в печь гарнисажеобразующей добавки, отличающийся тем, что в качестве гарнисажеобразующей добавки в печь загружают шунгит фракции 10-100 мм, содержащий 28-32% углерода и 58-60% SiO2, контролируют температуру периферийных углеродистых блоков футеровки на уровне стыка горна и лещади, и загрузку шунгита в количестве 2-6% от массы кокса осуществляют при положительном отклонении тренда средней температуры футеровки по окружности горна от установленного уровня более, чем на 10°С, причем загрузку шунгита производят в узкую периферийную зону колошника, ограниченную радиусами 0,8-1,0 радиуса колошника.1. A method of creating a protective skull on the lining of the hearth of a blast furnace, comprising loading a skull-forming additive into the furnace, characterized in that as a skull-forming additive, shungite of a fraction of 10-100 mm containing 28-32% carbon and 58-60% SiO 2 is loaded into the furnace control the temperature of the peripheral carbon blocks of the lining at the junction between the hearth and the bream, and the loading of schungite in the amount of 2-6% of the coke mass is carried out with a positive trend deviation of the average temperature of the lining around the hearth circumference from the set level olee than 10 ° C, the load shungite produce a narrow peripheral region of the furnace top bounded by radii 0.8-1.0 radius of the furnace top. 2. Способ по п.1, отличающийся тем, что контролируют температуру периферийных углеродистых блоков футеровки на уровне стыка горна и лещади по секторам его окружности, определяют сектор с максимальной температурой и, при ее отклонении от средней температуры кладки по окружности горна более, чем на 15°С, шунгит загружают в сектор колошника, расположенный над сектором горна с максимальной температурой футеровки.2. The method according to claim 1, characterized in that the temperature of the peripheral carbon lining blocks is controlled at the junction of the hearth and the bottom of the flank by sectors of its circumference, a sector with a maximum temperature is determined, and when it deviates from the average temperature of the masonry around the hearth more than 15 ° C, shungite is loaded into the top furnace sector located above the hearth sector with a maximum lining temperature. 3. Способ по пп.1 и 2, отличающийся тем, что шунгит загружают периодически, отдельными порциями массой 0,10-0,25% от массы порции кокса.3. The method according to PP.1 and 2, characterized in that the schungite is loaded periodically, in separate portions with a mass of 0.10-0.25% of the mass of a portion of coke.
