CONVERTER PURGE CONTROL METHOD AND CONVERTER PURGE CONTROL SYSTEM Russian patent published in 2024 - IPC C21C5/30 

FIELD: metallurgy.

SUBSTANCE: invention can be used in converter purge control to establish, by calculating the heat balance and calculating the material balance, the amount of oxygen to be supplied and the amount of cooling material or temperature-increasing material to be loaded, to regulate the temperature and concentration of the components of the molten steel to predetermined values at the end of the converter purge and control the converter purge based on the calculated amount of oxygen to be supplied and the calculated amount of cooling or temperature raising material to be charged. Also includes an estimate of the temperature of the molten iron before blowing, which is a standard indicator for calculating the heat balance, the specified temperature is the temperature of the molten iron used as the starting material for blowing, loaded into the converter and in the state immediately before the start of blowing, and the use of the estimated temperature of the molten iron before blowing as the temperature of the loaded molten cast iron when calculating the heat balance.

EFFECT: precise regulation of the temperature of the molten steel to a predetermined value at the end of the blowing process.
