METHOD FOR MONITORING THE STEEL PRODUCTION PROCESS Russian patent published in 2022 - IPC C21C5/28 C21C5/52 F27D19/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy and can be used for monitoring the steel production process. The steel production apparatus is loaded with the materials M_n, where each material has the corresponding properties P_Mn for producing steel and slag, wherein the coefficient n is greater than or equal to 2. At least one set of set characteristics TCS_Y of the produced liquid steel is determined; at least two set characteristics of the slag ST_X are determined; for each set characteristic of the slag ST_X, the amount AM_YX of materials needed to be loaded to achieve said at least one determined set of set characteristics TCS_Y is calculated, with account to the corresponding properties of each material P_Mn; wherein said amount AM_YX of materials includes a separate amount a_YXM_n of each of the loaded materials M_n.

EFFECT: possibility, to take into account, in addition to flux and oxygen, the amount and properties of metal waste and hot metal in the composition of the charge in the production of steel, thereby ensuring the accuracy of modelling the process and expanding the possibilities of achieving the set composition of steel.
