Description
Изобретение относитс к области черной металлургии, а именно к способам получени синтетического чугуна.The invention relates to the field of ferrous metallurgy, in particular to methods for producing synthetic iron.
Известен способ выплавки чугуна в доменных печах и выпуск его в предваритель но нагретый чугуновый ковш 1 .There is a method of smelting iron in blast furnaces and release it into a preheated but heated pig iron ladle 1.
Недостатком известного способа вл етс дополнительный расход электроэнергии, идущей на перегрев металлошихты и угар кремни и марганца, что приводит к снижению качества чугуна.The disadvantage of this method is the additional consumption of electricity, which leads to overheating of the charge and the waste of silicon and manganese, which leads to a decrease in the quality of cast iron.
Цель изобретени - сокращение энергозатрат на еыпйавку чугуна в доменных печах .: . :; , .;. The purpose of the invention is to reduce the energy consumption for the production of pig iron in blast furnaces.:. :; .;.

Способ заключаетс в следующем.-В предварительно нагретый футерова нный чугуновозный ковш до температуры 6ОО800 С загружают чугунный лом и вьщерживают его в течение 30-4О мин. При этомThe method consists in the following. In the preheated lined iron casting ladle, pig iron scrap is loaded to a temperature of 6OO800 C and held for 30-4 O min. Wherein
чугунный лом прогреваетс до ЗОО-400 С. После ..прогрева лома ковш устанавливают под выпуск чугуна. В процессе наполнени ковша чугуном, стру падающего чугуна попадает на лом и за счет физического тепла его происходит расплавление лома, а за счет энергии падающей струи-равномерное раЁ пределение расплавленного чугунного лома по всему объему чугуна в ковше. Снижение температуры чугуна в ковше 16-18 С на расплавление 1 т чугунгюголома при исходной температуре чугуна на желобе при выпуске 1350-14ОО°С.cast iron scrap is warmed up to ZOO-400 ° C. After the scrap is heated, the ladle is installed for the production of cast iron. In the process of filling the bucket with iron, the jet of falling iron gets on the scrap and due to the physical heat it melts the scrap, and due to the energy of the falling jet, a uniform melting of the cast iron scrap throughout the pig iron. Reducing the temperature of the iron in the ladle 16-18 C to melt 1 ton of pig iron at the initial temperature of the iron on the trough with the release of 1350-14OO ° C.
П р и М е р. В футерованный чугуновозный ЮО-т-ойный ковш, нагретый до 70О С загружают бракованную изложницу массой 10 т. Через 4О мин ковш устанавливают родвьшуек.чугуна..-При этом чугутшый лом ;Б ковше, i)-прогреваетс до 3SO С. Напол:нение ковша производитс передельным чугуном с температурой на желобе 136О140О°С и наливают 70 т чугуна. Угар марганца 0,13%, угара из набпюетс .PRI and MER. In a lined iron ore SO-bucket, heated to 70 ° C, a defective mold weighing 10 tons is loaded. After 4O min, the rod is set to rod.chuguna ..- At this, scrap metal; B bucket, i) - warms up to 3SO C. Napol: The bucket is produced by pig iron with a temperature on the chute 136О140О ° С and 70 tons of iron are poured. Manganese carbon monoxide 0.13%, carbon monoxide from carbon monoxide.
Полученный синтетический чугун полностью разливают на разливочной машине. Не расплавившихс счггатков чугунного лома и закозлвнй в ковше ие наблюпаетс .The resulting synthetic cast iron is completely bottled on a filling machine. The non-molten iron scrap and the molds in the ladle are not observed.
