Description
Изобретение отноаитс к металлургии черных металлов, в частности к технологии обработки (Металла жидкйм шлаком.The invention relates to ferrous metallurgy, in particular, to processing technology (Metal liquid slag.
Известен способ обработки металла жидким синтетическим шла,ком путем ввода в нижние слои металла под давлением, превышающим фер.ростатическое давление столба жидкого металла. Скоро сть нодачи шлака в металл регулируетс изменением давлени в емкости со шла,ком. Ооно)вным недоСтаткО|М этого способа вл етс отсутствие режимов рафинировк1и металла.A known method of treating metal with liquid synthetic slag is by entering into the lower layers of metal under pressure exceeding the fer.static pressure of the column of liquid metal. The rate of slag supply to the metal is governed by the change in pressure in the tank with slag. An unacceptable failure of this method is the absence of refining modes of the metal.
Кроме того, применение его затруднено при обработке расплава в самой электропечи.In addition, its use is difficult when processing the melt in the electric furnace itself.
С целью устранени указанных недостатков предложен способ, по которому iB металл пссле его расплавлени подают окислительный шлак со скоростью не ниже 12 м/сек, а при сливе металла из печ1и навстречу струе металла подают основной шлак со скоростью более 10 м/сек.In order to eliminate these drawbacks, a method has been proposed in which iB metal, when it is melted, serves oxidizing slag at a speed of not less than 12 m / s, and when discharging metal from the furnace and towards the stream of metal, basic slag is fed at a speed of more than 10 m / s.
Способ осушествл етс следуюшим образом .The method is as follows.
После расплавлени лггталлической шихты с целью дефосфора.ции металла и сокрашени длительности полировми под уровень металла подают под давлением жидкий окисллтельпый шлак, приготовленный вне -печи. Скорости подачи шлака превышают 12 м/сек. Большую часть шлака удал ют из печи по мере его подачи.After the melt of the melt batch is melted in order to dephosphorize the metal and shorten the duration by polishing under the metal level, liquid oxidized slag prepared outside the furnace is fed under pressure. Slag feed rates exceed 12 m / s. Most of the slag is removed from the furnace as it is fed.
После «кипа и доводки металла по химическому составу и температуре осуш.ествл етс раскисление и десульфурапи металла при сливе его из печи путем подачи основного шлака навстречу струе металла со скорост ми , превышаюшими 10 м/свк.After the bale and the finishing of the metal according to the chemical composition and temperature of drying, the deoxidation and desulfurapi of the metal take place when it is drained from the furnace by feeding the main slag towards the stream of metal at speeds exceeding 10 m / src.
Предмет изобретени Subject invention
Способ обработки металла жидким шлаком путем подачи его под давлением под уровень металла, отличающийс тем, что, с целью более глубокой дефосфорации, десульфурации и раскислени , в металл после его расплавлени подают окислительный шлак со скоростью не ниже 12 м/сек, а при сливе металла из печи .навстречу струе металла подают основной шлак со скоростью более 10 м/сек .The method of processing metal with liquid slag by supplying it under pressure under a metal level, characterized in that, in order to deeper dephosphorization, desulfurization and deoxidation, the oxidizing slag is fed into the metal after its melting and at a speed of at least 12 m / s. The main slag is fed from the furnace to the metal stream at a speed of more than 10 m / s.
