Abstract

Описані нові системи та способи для відновлення оксиду заліза до металевого заліза на заводі з повним металургійним циклом виробництва або подібному, на якому є коксова піч та/або сталеплавильна піч з подачею кисню. Більш конкретно, даний винахід належить до нових систем та способів для відновлення оксиду заліза до металевого заліза зі застосуванням коксового газу (COG) або COG та газу з основної сталеплавильної печі з подачею кисню (BOFG).
