The invention belongs to the technical field of continuous casting production, and relates to a method for determining the roller diameter and the roller spacing of a straightening section in a continuous casting reduction process. Obtaining the relationship between the maximum strain of the crack sensitive area and the roller diameter and the roller distance under the conditions of different roller diameters and different roller distances through a bloom continuous casting solidification heat transfer mathematical model and a high-temperature stress-strain model, and correspondingly establishing a relationship curve between the maximum strain of the crack sensitive area and the roller diameter and a relationship curve between the maximum strain of the crack sensitive area and the roller distance; meanwhile, a relation curve of the roller diameter and the deflection and a relation curve of the roller distance and the drum belly amount are established; reasonable roller row parameters of the casting machine ar
