This paper analyzes the influencing factors of ladle heat preservation technology, and puts forward the optimal structure of split flow channel with variable diameter. After the optimization, the temperature difference between each flow of the intermediate ladle is only 1-2 ℃, which not only ensures the heat preservation effect of the molten steel in the ladle, but also realizes the uniformity of the molten steel between each flow. At the same time, the transformation control of the ladle is conducive to the floating removal of inclusions and improves the quality of the ladle.
