Abstract
Запропоновано спосіб одержання агломерату відновленого заліза, який включає введення агломерату, що містить матеріал, який містить оксид заліза, вуглецевий відновник, регулятор температури плавлення, і допоміжний матеріал для регулятора температури плавлення, на під нагрівальної печі з рухомим подом, і потім нагрівання агломерату на поду печі для відновлення оксиду заліза в агломераті, розплавлення продукту, що виходить, шляхом додаткового нагрівання, щоб викликати коалесценцію залізної складової, таким чином, одержуючи агломерат відновленого заліза, причому використовують агломерат, що містить регулятор температури плавлення, який має середній діаметр частинок 0,3 мм або менше, і в якому вміст частинок діаметром 0,5 мм або менше – 55 мас. % або більше. Тим самим забезпечений спосіб, який дозволяє поліпшити вихід агломерату відновленого заліза, що має великий діаметр частинок, і зменшити проміжок часу, необхідний для одержання агломерату відновленого заліза, для підвищення виробництва агломерату відновленого заліза.A method of producing a recovered iron agglomerate is proposed, which comprises introducing an agglomerate containing a material containing iron oxide, a carbon reducing agent, a melting point regulator, and auxiliary material for a melting temperature regulator, under a mobile furnace heating furnace, and then heating the agglomerate furnaces for the reduction of iron oxide in the sinter, melting the resulting product by additional heating to cause the coalescence of the iron component, thus obtaining the agglomerate from ovlenoho iron, and use sinter containing melting temperature controller, which has an average diameter of 0.3 mm or less, and in which the content of particles with a diameter of 0.5 mm or less - 55 wt. % or more. This provides a method that improves the yield of the recovered iron agglomerate having a large particle diameter and reduces the time required to obtain the recovered iron agglomerate to increase the production of recovered iron agglomerate.
