The invention discloses a method for controlling the quality of a continuous casting billet on line, which comprises the following steps: arranging a temperature measuring device in front of a withdrawal and straightening machine, measuring the surface temperature of the casting billet in real time by the temperature measuring device, and adjusting the secondary cooling water quantity according to the surface temperature of the casting billet; measuring the cutting length of the casting blank and the weight of the casting blank, monitoring the section size of the casting blank, calculating the cutting section area, calculating the average density value of the casting blank by combining the length and the weight of the casting blank, and adjusting the cooling water amount of each secondary cooling zone of the continuous casting machine according to the section size of the casting blank and the average density value of the casting blank. According to the method for online control of the quality of the continuou
