Solid wastes in steel plants are essential by-products generated during various processing steps involved in the production of iron and steel. Solid wastes generated by integrated iron and steel works cause environmental pollution and therefore must be discarded. Until the last decade, the slag, dust and sludge generated by integrated steel plants was called waste", but now this term has been

The special feature of LEGRAN’s metal slag processing system at the Lippe Plant is the way the material is treated. The slag and spent refractories need to be pulverised before they can be processed and this job is carried out by a rod and ball mill which dates back to the time when the site used to produce aluminium. The quality and level of purity of the recovered metals are second to none

Global crude steel production in 2018 was approximately 1807.1 Mta. 70.8 % of the current crude steel production is accounted for by the BOF process, 28.8 % by the EAF process (Fig. 3) and only 0.4 % by other processes such as the Siemens Martin process. Derived from these figures, the annual quantities of steelworks slag amount to a total of 250 Mta, of which around 65 % are BOF or LD slags

on the plant configuration and availability of recycled steel, other sources of metallic iron such as direct-reduced iron (DRI) or hot metal can also be used in the EAF route. The main solid co-products produced during iron and crude steel production are slag (90% by mass), dust and sludge. Process gases, for example, from the coke oven, BF or BOF are also important co-products. However, this

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).

What we notice with this diagram is the variability (or the fuzziness of our knowledge) of flows for some materials, and the stability (or more precise knowledge) of others. For instance, the production of BF slag appears to be stable at 240 kg

The granulation plant converts molten iron from the Corex plant into solid granules, which permits the iron to be sorted in manageable form. The only emission resulting from the process is water vapour. The iron granules are produced from excess iron produced in the Corex unit.
