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.
