METHOD FOR OBTAINING CHARACTERISTICS OF VARIOUS TYPES OF STEEL SCRAP AND A CORRESPONDING METHOD FOR CONTROLLING AN ELECTRIC ARC FURNACE

Abstract

A method for characterizing different types of scrap (si), charged in an Electric Arc Furnace EAF (10) for producing steel, the method comprising: - acquiring operation data that comprise, for each heat (hj) of a series of successive heats achieved with the EAF: o for each type of scrap (si), a measured scrap amount (1) charged in the EAF, o for at least one residual element, a measured residual content (2) of said element in a liquid steel (S) output by the EAF, - determining, for two or more of said types of scrap: data representative of a probability distribution for the residual content of said residual element, in the type of scrap considered, given the operation data (OD) acquired, using a model of operation for the EAF.
