The invention provides a system for tracking data in a blast furnace. The system includes an acquisition module suitable for acquiring furnace burden data to be tracked in a database in a blast furnace control system; a processing module suitable for calculating burden batch position and burden layer thickness according to charging parameter sub information and system parameter information so as to generate a burden batch position information mirror image in the blast furnace, and calculating time for burden batch to arrive at a tuyere in the blast furnace so as to generate a core parameter tendency chart according to the time for the burden batch to arrive at the tuyere in the blast furnace and core parameter sub information; and a display module suitable for displaying correlated information of the burden batch position information, the core parameter tendency chart and burden batch parameter information when searching content is one or a plurality of kinds of information selected from the burden batch position information, the core parameter tendency chart and burden batch parameter information. According to the system, the furnace burden data in the blast furnace is tracked; the mirror image is generated according to the furnace burden data; the burden batch position information, the core parameter tendency chart and burden batch parameter information are correlated to each other; and when the data in the blast furnace are searched or observed, combination display can be realized, and the efficiency of real-time tracking and observation of the furnace burden data can be improved.
