Embodiment 2

[0125] Example 2: see figure 1 , figure 2 , A method for controlling the silico-manganese composition of molten steel in a ladle refining furnace, ladle refining includes LF refining furnace and RH refining furnace. As the process equipment to realize the intermediate process of converter and continuous casting, the ladle refining furnace must provide qualified molten steel that meets the requirements of quantity and composition, which is a prerequisite for the smooth progress of the subsequent process. As users have higher and higher requirements for the variety and quality of steel, higher requirements have been put forward for the control of the ladle refining process. The manganese alloys used for steelmaking include silico-manganese alloy, ferromanganese, high-carbon ferromanganese, medium-carbon ferromanganese and low-carbon ferromanganese. For manganese-containing steel, not only must the manganese content of the molten steel be qualified, the cost of adding the alloy i...
