in the mill scale and volatile materials in the solid carbon sources have a positive contribution on the increase of metallization degrees during the DR process [4, 5 and 6]. In this study, optimum conditions to produce highly metalized DRI from the mill scale formed on a continuous casting facility were investigated. The use of mill scale as
It is also observed that at larger size of mill scale ( µm), with and mill scale to coal ratio 1:3 for 45 mins heating time at 1000 °C, the obtained metallic iron is %. The same procedure is repeated only by changing the size of mill scale from 600 µm to 300 µm, the percentage of metallic iron is reduced further to %.

In addition, mill scale and weld scale can become deposit accumulation sites and may cause damage if they break loose. Removal of metallic scale and corrosion products generally requires chemical cleaning. Frequently, sand and dirt (which add scaleforming contaminants such as silica and calcium to the boiler water) can be removed by flushing.
