Summary:The invention discloses a rolling groove structure. The rolling groove structure comprises a precutting groove and a cutting groove, and is characterized in that as for the precutting groove, the space between cutting blades is 10.78-13.45 mm, and fillets of the cutting blades are 3.2-3.70 mm; and the included angle of cutting blades of the cutting groove is 45-48 degrees, and fillets of the cutting blades are 0.9-0.95 mm. According to the rolling groove structure disclosed by the invention, the grooves are optimized, high-temperature tearing of a cutting belt is beneficial for the process that the cutting belt is easy to laminate when entering the next pass of rolling after being torn, a precut rolled piece has good stability when entering the cutting groove, regulation and control of theline difference of the rolled piece are facilitated, and a finished product is more uniform in size; the cutting blades are good in abrasion resistance and are not prone to abrasion or chipping, andthe service life of the cu
