Изобреггение относитс к металлургии, в частности к способам заш.иты фурм конвертеров .The isobreggation relates to metallurgy, in particular to the methods of sutured by the tuyere converters.
Известен способ защиты фурм конвертеров, имеющих по меньщей мере два канала, включающий подачу защитного агента в пастообразном состо нии по меньшей мере в один канал.There is a known method of protecting lances of converters having at least two channels, including the supply of a protective agent in a pasty state to at least one channel.
Предложенный способ отличаетс тем, что в качестве зап1,итного агента используют одно из веществ, выбранное из rpyinibi: раствор парафина в жидком топливе, вазелин, полужидкие , м гкие или твердые смолы, т желое или сверхт желое жидкое топливо, мелкий, порошковатый или компактный кокс, взвесь угл в жидком или тестообразном веществе, раствор смолы или нефтекокса в жидком топливе , гудрон, полужидкий строительный раствор гудрона с огнеупорной добавкой. Это облегчает контроль и регулирование подачи защитного агента.The proposed method is characterized in that one of the substances selected from rpyinibi is used as a filling agent or an agent: paraffin in liquid fuel, petroleum jelly, semi-liquid, soft or solid gums, heavy or superfluous liquid fuel, fine, powdered or compact coke, coal suspension in a liquid or pasty substance, a solution of tar or oil coke in liquid fuel, tar, semi-liquid mortar tar with a refractory additive. This facilitates the control and regulation of the supply of the protective agent.
Способ осуществл ют следующим образом.The method is carried out as follows.
Через фурмы конвертера с раздельной двукратной или многократной подачей по одному каналу, который-может быть центральным , продуваетс ..окислительный газ, например чистый кислород, а по друго-му минимум по одному, каналу фурмы, который может быть периферическим, подаетс в зкое, тестообразное или порошкообразное и опрессованное вещество, содержащее углерод, и, в частности , т желые углеводороды, защищающие носик фурмы от износа в результате нагревани .Through the tuyeres of the converter with a separate double or multiple supply through one channel, which may be central, an oxidizing gas, such as pure oxygen, is blown through, and through another at least one, the channel of the tuyere, which may be peripheral, is visually supplied, a pasty or powdery and pressed carbon-containing substance, and in particular heavy hydrocarbons protecting the tuyere nose from wear by heating.
Пример. Фурма состоит из двух концентрических труб, причем внутренн труба пмеет внутренний диаметр 20 мм п внешний диаметр 25 мм, а внешн труба имеет внутренний диаметр 30 .мм и внешний диаметрExample. The lance consists of two concentric tubes, the inner tube has an inner diameter of 20 mm and an outer diameter of 25 mm, and the outer pipe has an internal diameter of 30 mm and an outer diameter
35 мм. Обе трубы строго центрируютс одна Б другой известным способом. В фурме по внутренней трубе продуваетс чистый кислород из расчета 25 под давлением 12 бар, а по внешней трубе - необработанный35 mm. Both pipes are strictly centered one B the other in a known manner. In the tuyere, pure oxygen is blown through the inner tube at the rate of 25 under a pressure of 12 bar, and through the outer tube - raw
вазелин из расчета 1 кг/.мин посредством смазочного прибора известного типа, отрегулированного на врем минимум одной операции рафинировани в конвертере. При продувке в течение 10 мин потребление фурмой вазелина составл ет 10 кг на операцию. Таким образом, дл конвертера, в который подаетс 25 т жидкого чугуна и днище которого имеет шесть фурм, одинаковых с предыдущей, общее потребление вазелина 60 кг, т. е. примерно 2,5 кг на тонну получаемой стали.petrolatum at the rate of 1 kg / .min by means of a lubricant device of a known type adjusted to the time of at least one refining operation in the converter. When purging for 10 minutes, the consumption of vaseline by the tuyere is 10 kg per operation. Thus, for a converter in which 25 tons of liquid iron are supplied and the bottom of which has six tuyeres identical to the previous one, the total consumption of vaseline is 60 kg, i.e. about 2.5 kg per ton of steel produced.
Предмет изобретени Subject invention
Способ защиты фурм конвертеров, имеющих ПО меньшей мере два канала, включающий подачу защитного агента в пастообраз3 ком состо нии по меньшей мере в один канал , отличающийс тем, что, с целью облегчени контрол и регулировани подачи защитного агента, в качестве последнего используют одно из веществ, выбранное из груп-5 пы: раствор парафина в жидком топливе, вазелин , полужидкие, м гкие или твердые смо4 лы, т желое или сверхт желое жидкое топЛИБО , мелкий, порошковатый или компактный кокс, взвесь угл в жидком или тестообразном веществе, раствор смолы или нефтекокса в жидком топливе, гудрон, полужидкий строительный раствор гудрона с огнеупорной добавкой .A method of protecting converters tuyeres having at least two channels, including the supply of a protective agent in a paste-like state to at least one channel, characterized in that, in order to facilitate the control and regulation of the supply of a protective agent, one of selected from the group of five pys: paraffin solution in liquid fuel, petrolatum, semi-liquid, soft or solid resins, heavy or super heavy liquid, tLIBO, fine, powdered or compact coke, coal suspension in a liquid or pasty substance, a solution of tar or neftekoksa in liquid fuel, tar, semi-liquid mortar tar with a refractory additive.
