Abstract
FIELD: metallurgy. SUBSTANCE: structure is made of horizontal heat-resistant material sheet tightly joined to furnace housing and with free end touching surface of carbon wall. Water, that comes from cooling members into furnace, is carried out from carbon blocks inside hearth, due to that carbon lining oxidation, smelt pig-iron approach to pig-iron coolers and side penetration of hearth are avoided. EFFECT: blast-furnace cooling members water coming into hearthcarbon lining and bottom is avoided.

Предложено устройство для предотвращения попадания воды от течи охлаждаемых элементов доменной печи в углеродистую футеровку горна и лещади. Устройство состоит из горизонтального листа, выполненного из жаростойкого материала, плотно соединенного с кожухом печи и свободным концом доведенным до поверхности углеродистой стенки. Вода, попадающая из охлаждаемых элементов в печь, отводится от углеродистых блоков внутрь горна, благодаря чему исключается окисление углеродистой футеровки, предотвращается подход жидкого чугуна к чугунным холодильникам и боковой прорыв горна.A device is proposed for preventing water from leaking from the cooled elements of a blast furnace into the carbon lining of a hearth and flask. The device consists of a horizontal sheet made of a heat-resistant material tightly connected to the casing of the furnace and the free end brought to the surface of the carbon wall. Water entering the furnace from the cooled elements is discharged from the carbon blocks into the hearth, which eliminates the oxidation of the carbon lining, prevents the approach of molten iron to cast-iron refrigerators and side breakthrough of the hearth.
