уменьшить количество врезОк в катьцевои {воздухопровод гор чего дуть  и количество фурменных рукавов на 50Vo. В результате стойкость кольцевого воздухопровода повыситс  на 20-3()/о. а снижение теплопо тёрь в окружающую среду приведет к возрастанию температуры гор чего дуть  на 20-30°С, что позволит получить ориентировочный годовой экономический эффект в размере 120 тыс. руб. применительно к доменной печи полезным объемом 3000 м. Предложенное устройство дл  подвода гор чего дуть  к фурменным приборам доменной печи в сочетании с устройствами механизированной замены фурм позвол ет создать высокопроизводительный процесс и исключить ручной труд при замене фурм. Ориентировочный .экономический эффект составит 40 тыс. руб. в год. Формула изобретени  Устройство дл  подвода гор чего дуть  к фурмам доменной печи, содержащее кольцевой воздухопровод гор чего дуть -, встроенные в него фурменные рукава, фурменные приборы, отличающеес  тем, что, с целью создани  условий дл  механизированного обслуживани  фурменных приборов и уменьшение количества врезок в кольцевом воздухопроводе , фурменные рукава выполнены с двум  противоположными патрубками, концы которых присоединены к фурменным приборам.

As a result, the durability of the annular air duct will increase by 20-3 () / o. and the reduction of heat to the environment will lead to an increase in the temperature of the hot blast by 20–30 ° C, which will allow us to obtain an estimated annual economic effect of 120 thousand rubles. applied to a blast furnace with a usable volume of 3000 m. The proposed device for supplying hot blowing to blast furnace appliances in combination with devices for mechanized replacement of tuyeres allows creating a high-performance process and eliminating manual labor when replacing tuyeres. The estimated economic effect will be 40 thousand rubles. in year. Apparatus of the Invention A device for supplying a hot blast to the blast furnace tuyeres containing an annular air duct of a hot blast, tuyere sleeves embedded in it, tuyere devices, characterized in that in order to create conditions for the mechanized servicing of the tuyeres and reducing the number of tie-ins in the air duct, tuyere sleeves are made with two opposite nozzles, the ends of which are attached to tuyere instruments.
