Изо етение относитс к черной гжталлургии, в частности к устройствам дл донной продувки металла и может быть использовано в конвертерных цехах металлургических заводов.The insulation refers to ferrous metallurgy, in particular, to devices for the bottom blowing of metal and can be used in the converter shops of metallurgical plants.
Наиболее близкой к изобретению по технической сущности и доститаемому результату вл етс фурма дл донной продувки металла в конвертере , содержаща кЬнцентрично расположенные внутреннюю дл подачн окислител и наружную трубы, образующие кольцевой проход дл подачи охлажданнцего таза 1 .Closest to the invention in terms of technical essence and the result achieved is a lance for bottom blowing metal into a converter, containing kH-centrically located inner for oxidant feed and outer tube, forming an annular passage for feeding a cooled pelvis 1.
Одаако вьшолнение внутренней трубы в такой фурме с гадравлическим диаметром, не превышающим 1/35 тлубины конвертерной ванны, ведет к тому, что продувочна стру значительно заглубл етс в металлическую ванну, что, в свою очередь, приводит к повыщенному вьшосу металла из конвертера и снижению выхода жидкого.Odakan execution of the inner tube in such a lance with a hydraulic diameter not exceeding 1/35 of the depth of the converter bath leads to the fact that the blow-down jet dives significantly into the metal bath, which in turn leads to a heightened metal output from the converter and a decrease in output liquid.
С целью повышени эффектавности продувки, гадравлический дааметр внутренней трубы составл ет 1/25-1/13 глубины конвертерной ванны.In order to increase the efficiency of the purge, the hydraulic diameter of the inner tube is 1 / 25-1 / 13 of the depth of the converter bath.
На чертеже изображена предлагаема фурма (в днище конвертера вмонтированы две фурмы) .The drawing shows the proposed lance (two tuyeres are mounted in the bottom of the converter).
Фурма 1, вмонтирова ша в ак11ще конвертера 2 состоит из наружной 3 и внутрс1пгей.4 труб, The lance 1, mounted in the shaft of converter 2, consists of an outer 3 and an inner 1 tube, 4 pipes,
а зазор 5 между которыми вставлена разделительна вставка 6. Трубы 3 и 4 могут иметь круглое , квадратное, ромбическое, пр моугольное, зллипсоидное, овальное сечени . Обща площадь поперечных сече1шй наружных труб в см равна садке конвертера, выраженной в тоннах.and a gap 5 between which a spacer insert 6 is inserted. The pipes 3 and 4 may have a circular, square, rhombic, rectangular, zllipsoidal, oval section. The total cross-sectional area of external pipes in cm is equal to the converter charge, expressed in tons.
Гидравлический диаметр трубы 4 составл ет 1/25-1/13 глубины ванны конвертера.The hydraulic diameter of the pipe 4 is 1 / 25-1 / 13 of the depth of the bath of the converter.
Фурма работает следующим образом.The lance works as follows.
Кислород под давлением (примерно 1 атм) с расходом 2352 подают по трубе 4 под уровень конвертерной ванны, глубина которой 81,3см. Гидравлический дааметр трубы 4 составл ет 1/14 от глубины металлической ванны.Oxygen under pressure (approximately 1 atm) with a flow rate of 2352 is fed through pipe 4 under the level of a converter bath, which is 81.3 cm deep. The hydraulic pipe diameter 4 is 1/14 of the depth of the metal bath.
Защитный газ подают но зазору 5, дл обеспечени равномерности которого служит разделительна вставка 6.Shielding gas is supplied to the nip 5, for the sake of uniformity which serves as a separating insert 6.
