Description

Изобретение относитс к доменному, мартеновскому и конверторному производству чугуна и стали и может быть использовано также в других технологических процессах в агрегатах, где необходимо устройство дл ввода топлива и окислител либо реагента в расплав.The invention relates to the blast furnace, open-hearth and converter production of iron and steel and can also be used in other technological processes in units where a device is needed for introducing fuel and oxidant or reagent into the melt.
По основному авт. св. № 551369 известна дутьева фурма, содержаща корпус, состо щий из жестко скрепленных между собой двухфазных термосифонов, соединенных с теплообменником и покрытых снаружи огнеупорной изол цией, причем термосифоны размещены по ее периметру, а водоохлаждаемый теплообменник выполнен из коаксиально расположенных труб, установленных перпендикул рно термосифонам вдоль образующей корпуса фурмы 1.According to the main author. St. No. 551369 is known for blowing a tuyere, containing a body consisting of two-phase thermosyphons rigidly fastened together, connected to a heat exchanger and covered with a refractory insulation outside, with thermosyphons located along its perimeter, and the water-cooled heat exchanger is made of coaxially arranged pipes mounted perpendicular to it forming the body of the tuyere 1.
Однако известна фурма обладает следующими недостатками: в случае резкого увеличени теплового потока в рыльной части фурмы (при попадании на поверхность расплавленного чугуна) термосифоны в этой части могут работать в начальный период с недостатком теплоносител .However, the known lance has the following disadvantages: in case of a sharp increase in the heat flux in the ryl part of the lance (when molten iron hits the surface), the thermosyphons in this part can operate in the initial period with a lack of heat carrier.
а затем и вовсе без него, что может привести к местным перегревам и прогару корпуса .and then completely without it, which can lead to local overheating and burnout of the hull.
Таким образом, основным недостатком известных устройств вл етс их недостаточна надежность в работе.Thus, the main disadvantage of the known devices is their lack of operational reliability.
Целью изобретени вл етс повышение стойкости и надежности фурмы.The aim of the invention is to increase the durability and reliability of the tuyere.
Поставленна цель достигаетс тем, что фурма снабжена коллектором, расположенным вдоль образующей корпуса перпендикул рно к термосифонам и соедин ющим их в нижней части.The goal is achieved by the fact that the lance is provided with a collector located along the generators of the body perpendicular to the thermosyphons and connecting them in the lower part.
При внезапном увеличении нагрузки теплоноситель перераспредел етс по всем термосифонам до полного распределени нагрузки на фурму.With a sudden increase in the load, the coolant is redistributed over all thermosiphons until the load on the lance is completely distributed.
На фиг. 1 изображена фурма, продольный разрез; на фиг. 2 - разрез А-А фиг. 1.FIG. 1 shows a tuyere, a longitudinal section; in fig. 2 - section A-A of FIG. one.
Корпус фурмы выполнен из двухфазных термосифонов 1, изогнутых по периметру и покрытых снаружи огнеупорной изол цией , концы которых выведены в теплообменник 2, расположенный перпендикул рно термосифонам 1 И охЛ|аждаемый водой, подаюThe body of the tuyere is made of two-phase thermosyphons 1, bent around the perimeter and covered outside with refractory insulation, the ends of which are led out to the heat exchanger 2, which is perpendicular to the thermosyphons 1 and cooled by water.
