Abstract

Для збільшення розділюваності відновленого заліза й шлаку у суміші відновленого заліза та шлаку, одержаної в напіврозплавленому стані, в якому цілий згрудкований матеріал розплавлений не повністю, запропонований спосіб виготовлення суміші відновленого заліза й шлаків, який містить у наступному порядку: етап агломерування речовини, що містить оксид заліза і оксид титану, у суміші вихідних матеріалів в якій, крім того, додані регулятор температури плавлення та вуглецевий матеріал, і етап нагрівання агломерату, що виходить у результаті, для того, щоб розплавити частину агломерату, що виходить в результаті, для відновлення оксиду заліза, який міститься в цьому агломераті.To increase the separability of recovered iron and slag in a mixture of recovered iron and slag obtained in the molten state, in which all the crumpled material is not fully melted, a method of manufacturing a mixture of recovered iron and slag containing in the following order is provided: iron and titanium oxide, in a mixture of starting materials in which, in addition, a melting point regulator and a carbon material are added, and the resulting sintering step is heated. I have to melt part of the agglomerate, which is obtained for the recovery of iron oxide contained in the agglomerate.
