Изобретение относитс к металлургии.The invention relates to metallurgy.
Известно устройство дл слива стали из электропечи, состо щее из футерова нного желоба , закрепленного на кожухе печи. При наклоне лечи вначале сходит часть шлака, затем сливаетс сталь. Стру стали, нада с больHIOH высоты на слой шлака, смешиваетс с ним, и частицы шлака эмульгируют в металл. Часть шлака остаетс в стали в виде неметаллических включений и вл етс причиной .худшени качеств;-, стали.A device for discharging steel from an electric furnace is known, which consists of a lining groove attached to the furnace shell. When tilting, the leci first comes off part of the slag, then the steel is drained. A stream of steel, nada with a high HIOH height onto the slag layer, is mixed with it, and the slag particles are emulsified into metal. Part of the slag remains in the steel in the form of non-metallic inclusions and is the cause of the worst quality; - steel.
Дл уменьшени содержани неметаллических включений li стали предлагаемое устройство состоит из желоба, на конце которого шар«ирно закреплена воронка.In order to reduce the content of non-metallic inclusions li steel, the proposed device consists of a groove, at the end of which the ball is “irreactively fixed funnel.
Кроме тото, дл лучшего слива стали конец желоба выполнен в виде сферы, в нижней части которой имеетс щель, выт нута в направлении .продольной оси желоба.In addition to this, in order to better drain the steel, the end of the chute is made in the form of a sphere, in the lower part of which there is a slit, stretched in the direction of the longitudinal axis of the chute.
Дл предотврац1ени вторичного окислени стали желоб снабжен плотно закрывающейс крышкой. Иаличие пористого огнеупорного блока в нижней части желоба позвол ет улучшить качество стали за счет продувки ее инертными газами при сливе из электропеч-и. Улучшепие условий слива стали и дополнительное иовыше 1ие :качества стали дости-гаютс за счет установки в верхней части подвижной еороики пористого огнеупорного блока.To prevent the secondary oxidation of steel, the chute is provided with a tightly closing lid. The presence of a porous refractory block in the lower part of the gutter allows to improve the quality of steel by blowing it with inert gases when draining from the electric furnace. Improving the conditions for the discharge of steel and additional and higher 1: the quality of steel is achieved by installing a porous refractory block in the upper part of the movable eoroic.
На чертеже показаны электропечь и олисываемое устройство с разрезами но А-.4 и Б-Б.The drawing shows an electric furnace and olisyvaemoe device with cuts but A-.4 and BB.
К кожуху электропечи / прикреплен футерованный желоб 2, конец которого вынолнен н виде сферы, имеющей в части щель, ,ыт 1утую вдоль продольной оси желоба. Сверху желоб накрываетс крышкой 5, а в нижней его части устанавливаетс пористый огнеупорный блок 4. На конце желоба наход тс ца-пфы 3, к которым при помощи подшипникового узла 6 крепитс подвижна воронка 7, вход ща при сливе стали из электропечи в сталеразливочный ковш 8. Б верхней части подвил ной воронки размещаетс пористый огнеупорный блок 9.A lined groove 2 is attached to the electric furnace casing / 2, the end of which is made in the form of a sphere having a slit in the part, which is 1 foot along the longitudinal axis of the groove. On top of the chute is covered with a lid 5, and in its lower part a porous refractory block 4 is installed. A porous refractory block 9 is placed in the upper part of the basement funnel.
Перед наклоном электропечи / дл выпуска стали желоб 2 накрывают крышкой 3 и воронку 7 ввод т в ковш 8. Одновременно с началом слива стали ,к пористому огнеупорному блоку 4 подвод т инертный газ и продувают сталь, проход щую по желобу. Сталь проходит по желобу 2, далее через щель в конце его попадает в вороику 7 и сходит в ковщ 8. При прохождении стали но воровке производитс продувка ее инертным газом через пористый огнеупорный блок 9. Благодар шарнирному креплению воронка сохран ет вертикальное положение при нажлсне печи.Before tilting the electric furnace / for steel production, chute 2 is covered with lid 3 and funnel 7 is introduced into the ladle 8. At the same time as the steel begins to drain, inert gas is supplied to the porous refractory block 4 and the steel passing through the chute is blown. The steel passes through chute 2, then through the slit at the end of it enters the blade 7 and goes into the bucket 8. When the steel passes, the thief is blown with an inert gas through the porous refractory block 9. Thanks to the hinged fastening, the funnel maintains a vertical position when the furnace is pressed.
При сливе стали нижний конец воронки находитс в ковше под слоем шлака. Благодар When the steel is drained, the lower end of the funnel is in the ladle under a layer of slag. Thanks
