IC (57) Abstract: A converter CO 2-0 2 mixed injection smelting method and a dynamic temperature control method in a fire-point region.  
The method realizes online monitoring through an infrared temperature sensor installed inside an oxygen lance (1), dynamically adjusts 
enlthe mixing ratio of CO 2 and 0 2 and the height of the oxygen lance according to the temperature change and process requirements of 
the fire-point region in different stages of smelting, and realizes the interlocking of a smelting secondary system to dynamically control 
the temperature of the fire-point region and the heating rate of a molten pool.
