Изобретение относитс к металлургии, к внепечной обработке жидких металлов.The invention relates to metallurgy, to secondary treatment of liquid metals.
Известны установки дл рафинировани чугуна жидким синтетическим шпаком, coaeiжащие рафинировочную емкость, шпакоппа- вильную печь, желоба заливки чугуна и подачи окислител .Installations for the refining of cast iron with liquid synthetic putty, coaeiing the refining tank, kiln furnace, cast iron pouring channel and oxidant supply are known.
Недостатком таких установок вп егс высокий расход дорогосто щего синтетического шпака, большие энергетические потери, периодичность режима работы и назка рентабельность установок.The disadvantage of such installations is the high consumption of expensive synthetic pork, high energy losses, the frequency of operation and the profitability of installations.
С целью снижени расхода синтетического шлака и достижени непрерывности ведени процесса по предлагаемому способу ра- финировочна емкость соедин етс с шпакоплавильной печью двум расположенными на разных уровн х переточными каналами, а в шлакоплавильной печи выполнена детка дл выпуска ферросплава.In order to reduce the consumption of synthetic slag and to achieve continuity of conducting the process according to the proposed method, the refining tank is connected with two accumulation channels located at different levels, and in the slag-melting furnace a child is made for the production of ferroalloy.
На чертеже показано предлагаемое устройство .The drawing shows the proposed device.
Устройство включает шлакоплавильную дечь 1, соединенную с рафинировочной емкостью 2 переходными каналами 3 и 4,The device includes a smelting furnace 1, connected to the refining tank 2 by transition channels 3 and 4,
нижним и верхним соответственно,;которые объедин ют их в единую установку. Шлакоплавильна печь электрическа , однофазна с электродом 5 и токопровод щим дном, имеет летку б дл периодического спуска ферросплава 7. Над рафинировочной емкостью котора имеет металлическую |летку 8 дл спуска рафинированного металла 9, расположены желоб 10 дл заливки и дроблени на капли рафинируемого металла и желоб 11 подачи измельченной железной руды дл окапины, подаваемой одновременно с зали&кой металла. Переходный канал 3 по высоте расположён выше, чем летки 8 и 6.lower and upper respectively, which combine them into a single installation. Slag-smelting furnace is electric, single-phase with electrode 5 and conductive bottom, has a notch b for periodically lowering the ferroalloy 7. Above the refining tank which has a metal notch 8 for lowering the refined metal 9, the groove 10 is located for pouring and crushing the refined metal into drops and the groove 11 supplying crushed iron ore for an ocapina supplied simultaneously with the filled & metal. The transition channel 3 in height is located higher than the tap-holes 8 and 6.
Установка работает следующим образом.The installation works as follows.
В начале запуска в шлакоплавильной печи 1 плавитс , а затем перегреваетс синтетический шлак. В это врем летки 8 и 6 и переходный канал 3 закрыты. После пер грева синтетического шлака .в печи 1 открь ваетс нижний переходной канал 3, и готовый шлак самотеком перетекает в рафинировочную емкость 2. Одновременно начинают заливать рафинируемый жидкий металл, дроб его на капли, подавать окислитель иAt the start of the run in the slag-melting furnace 1, the synthetic slag is melted, and then the synthetic slag is overheated. At this time, tap holes 8 and 6 and transition channel 3 are closed. After overheating of the synthetic slag. In the furnace 1, the lower transition channel 3 is opened, and the finished slag flows by gravity into the refining tank 2. At the same time, the refined liquid metal is poured, shot into drops, fed oxidant and
