Изобретение относитс к черной металлургии, в частности к конструкци м фурм доменных печей.This invention relates to ferrous metallurgy, in particular to the designs of blast furnace tuyeres.
Наиболее близкой к предлагаемой по технической сущности и достигаемому результату вл етс дутьева фурма доменной печи, содержаща охлаждаемый корпус, пропущенную через него трубку дл подачи природного газа в рабочий канал и смонтированную в этом канале с зазором относительно внутренней стенки корпуса и концентрично ей экранирующую вставку 1 ,Closest to the proposed technical essence and the achieved result is the blast tuyere of the blast furnace, containing a cooled body, a tube passed through it for supplying natural gas into the working channel and mounted in this channel with a gap relative to the inner wall of the body and concentric shielding insert 1,
Недостатком данной фурмы в - л етс снижение тумпературы гор чего дуть за счет теплопотерь с охлаждающей водой. The disadvantage of this tuyere is the reduction of hot-blown temperature due to heat losses with cooling water.
Цель изобретени - повышение температуры гор чего дуть путем уменьшени теплопотерь с охлаждающей водои ,The purpose of the invention is to increase the temperature of a hot blow by reducing heat loss from the cooling water,
Поставленна цель достигаетс тем, что в дутьевой фурме, содержащейThe goal is achieved by the fact that in a blowing tuyere containing
охлаждаемый корпус с рабочим каналом , в котором с зазором относительно внутреннней стенки корпуса и концентрично ей расположена экранирукнца вставка, выполненна из жаропрочного металла, зазор, образованный вставкой и внутренней стенкой корпуса, выполнен герметичным и вакуумирован.the cooled housing with a working channel in which the screened insert is located with a gap relative to the inner wall of the housing and concentric with it is made of a heat-resistant metal, the gap formed by the insert and the inner wall of the housing is sealed and evacuated.
На чертеже изображена предлагаема фурма.The drawing shows the proposed lance.
10ten
Фурма состоит из корпуса 1, водоохлаждаемой полости 2, рабочего канала 3, трубки 4, подвод щей газ, вакуумированного зазора 5, образован ного вставкой 6, выполненной из жа15 ропрочного металла, на рабочей поверхности которой нанесено покрытие из окислов тугоплавкого металла, и внутренней стенкой 7 корпуса 1,The lance consists of a housing 1, a water-cooled cavity 2, a working channel 3, a tube 4, a supply gas, a vacuumized gap 5 formed by an insert 6 made of a heat-resistant metal, the working surface of which is coated with a refractory metal oxide and an internal wall 7 housing 1,
Фурма работает следующим обра20 зом.The lance works as follows.
