Abstract In order to utilize Cr-and-Ni bearing rolling scales produced in staleless steel works in the dephosphorization process and recycle valuable metals, melting experiments of dephosphorizing agents and dephosphorization experiments of hot metal were carried out, with dephosphorization fluxes of varying compositions prepared with various proportion of Cr-and-Ni bearing rolling scales instead of sintering ore. It is feasible to use Cr-and-Ni bearing rolling scales to replace 50% of the sintering ore in dephosphorizer, with the ratio of lime and fluorite to iron oxide is less than 1 in the dephosphorization fluxes.
