.Изобретение относитс к цветной .металлургии и- может быть использовано при переработке железистых шлаков медеплавильного производства и получение медистых чугунов.The invention relates to non-ferrous metallurgy and can be used in the processing of ferrous slag from copper smelting and the production of copper iron.
Цель изобретени - сокращение длительности процесса восстановлени железа.The purpose of the invention is to reduce the duration of the iron reduction process.
Способ осуществл ют следующим образом.The method is carried out as follows.
Железосодержащие отвальные шлаки медеплавильного производства разогревают и плав т в присутствии извести и твердого или газообразного восстановител . Перед плавлением в пшак ввод т закись меди до достижени ее содержани в шлаке 5-25%. Взаимодействие закиси меди с восстанови- ;телем приводит к по влению в распла- :ве корольков меди, которые по мере прохождени через расплав укрупн ютс , захватыва частички восстановленного железа которое при температуре процесса не успевает расплавитьс , и собираютс на дне реактора , образу расплав медного чугуна,The iron-containing waste slag from the copper smelter is heated and melted in the presence of lime and a solid or gaseous reducing agent. Before smelting, copper oxide was introduced into pshak until its content in the slag reached 5-25%. The interaction of cuprous oxide with a reduced body leads to the appearance of copper particles in the melt, which, as they pass through the melt, are enlarged, capturing particles of reduced iron which at the process temperature does not have time to melt, and collect at the bottom of the reactor. cast iron,
Введение в шлак закиси меди в количестве , обеспечивающем ее содержа- . ние в шлаке менее 5%, не позвол ет существенно снизить длительность ;процесса восстановлени .The introduction of copper oxide into the slag in an amount that provides it with The reduction in the slag less than 5% does not allow a significant reduction in the duration of the recovery process.

Кедение в шлак закиси меди в количестве , обеспечивающем ее содержание в шлаке более 25%, не приводит к дальнейшему снижению длительности процесса восстановлени и вызывает получение некондиционного по меди чугуна.Catching copper oxide in slag in an amount that provides its content in the slag of more than 25% does not lead to a further reduction in the duration of the reduction process and causes the production of iron-poor copper.
Пример. Восстанавливают железо из шлака окисью углерода. Температура газа-восстановител , Содержание закиси меди в шлаке измен ют путем добавки меди в пределах 0-30%. Б результате восстановлени получают медистый чугун (Fe : 85%).Example. Iron is reduced from slag with carbon monoxide. The temperature of the reducing gas, the content of cuprous oxide in the slag is changed by adding copper in the range of 0-30%. As a result of reduction, copper iron is obtained (Fe: 85%).
Результаты приведены в таблице.The results are shown in the table.
Способ позвол ет уменьшить длительность процесса восстановлени железа из железосодержащих ишаков на 50%.The method makes it possible to reduce the duration of the process of reducing iron from iron-containing donkeys by 50%.
