Zusammenfassung:The invention discloses an LF refining end-point temperature prediction method based on target linkage, mainly relates to the technical field of LF refining end-point temperature prediction, and is used for solving the problem of inaccurate end-point temperature prediction of an existing method. Comprising the following steps: determining a plurality of combinations of a continuous casting machine corresponding to molten steel refining modes; obtaining the adduct data of the temperature drop value of each combination and turnover package process and the package condition temperature drop compensation value along with the time change; importing the time-varying adduct data into a preset curvilinear equation to obtain a first curvilinear equation and a second curvilinear equation corresponding to each combination; a preset temperature value is obtained, and the current temperature corresponding to LF refining is determined according to the preset temperature value and the first curvilinear equation; and when th
