اقرأ أكثرIn the primary process, crude steel is produced in two ways. In the first method, the iron is produced from ore in the BF, thus, generating BF slag (BFS). BBOF slag (BOFS) is produced in the steelmaking process by using the molten iron coming from the BF. In the second method, slags are generated in the scrap-based steel industry.
اقرأ أكثرThe highest NNPs were for modern iron granulated slag and the coarse size fractions of modern, air-cooled iron and steel slags . Interestingly, two legacy samples, one a composite of coarse air-cooled (ILSS1), the other C-fines (ILSS2) offered comparable neutralization potentials to the modern materials.
اقرأ أكثرTypically, the manufacturing process of iron and steel can be divided into two major groups: (1) integrated mill using natural ore to produce iron and steel and (2) electric arc furnace using scrap to remake iron and steel. 1.1 Integrated Mill Process Figure 11.1 shows the schematic diagram of an integrated mill manufacturing process.
