A smelting furnace method based on bottom-blown oxygen lance

Abstract

This invention discloses a smelting method for a bottom-blown oxygen lance-based furnace, comprising: designing a new smelting furnace or establishing a numerical simulation platform for the thermal process of the oxygen-enriched bottom-blown molten pool furnace based on furnace design parameters; establishing the kinetic-thermodynamic transient morphology of the smelting furnace based on the real-time smelting process using the numerical simulation platform; transmitting and displaying the kinetic-thermodynamic transient morphology to a DCS system; the DCS system performing frequency conversion control on a variable frequency microcomputer controller based on the real-time smelting process to enhance heat transfer in the smelting furnace; and the DCS system controlling the oxygen enrichment frequency of the bottom-blown oxygen lance through the variable frequency microcomputer controller. This invention improves the production efficiency of the smelting furnace, enhances heat transfer, and achieves optimal molten pool stirring effect with minimal energy consumption.
