The invention relates to the field of steel coil production quality control in the steel production industry and provides a method for processing data of a system for controlling the steel coil production process quality. The method comprises the following steps: selecting reference points for calculating the length on a production line of the steel coil; reading sampling period data one by one from a server of the steel coil production quality control system; calculating the length Dn(i) which is the distance that the steel coil passes through a sensor having the tag number of Tag i at a sampling moment Tn; generating and storing a sequence table which comprises the steel coil number, the sampling moment Tn, the measurement value of a station, and the lengths which is the distance that the steel coil passes through a sensor having the tag number of Tag i at the sampling moment Tn as the table head; and outputting the sequence table. The sequence table of the steel coil length value corresponding to the measu
