Abstract

We should point out that at an integrated steel plant, the by-products recycling in the sinter plant depends on the initial treatment of these materials. At ArcelorMittal Monlevade, this treatment originally consisted of the following steps: screening, proportioning and mixing operations. A wheel loader was used for materials handling operations. Considering the strict Zn input control in the blast furnace, the basic oxygen furnace (BOF) sludge use was not allowed due to the treatment conditions. Aiming at improving this treatment, a new plant was commissioned. After that, the BOF sludge consumption was started. The current BOF sludge consumption is 450 tons per month (3.2 kg of steelshop sludge per ton of sinter).
