Zusammenfassung:The invention provides a method and device for adjusting the bottom blowing flow of a converter, a medium and equipment. The method comprises the steps that the thickness of the bottom of the converter is obtained based on a preset thickness measuring period; determining the erosion speed of a furnace bottom lining brick based on the furnace bottom thickness; the flow of the bottom blowing main pipeline is adjusted according to the erosion speed; in the smelting process, the end point carbon-oxygen product of the converter is obtained based on the preset smelting heat, and the bottom blowing flow of each branch pipe is adjusted in real time; therefore, firstly, the flow of the main pipeline is subjected to macroscopic adjustment (coarse adjustment) based on the erosion speed, and then the bottom blowing flow of each branch pipe is adjusted in real time based on the carbon-oxygen product, which is equivalent to fine adjustment of the bottom blowing flow, so that the bottom blowing flow of the converter can be
