| Abstract: |
| The equipment structure，reaction mechanism and radiation uniformity evaluation method of electron beam irradiation prevulcanization technology were described. The application of electron beam irradiation prevulcanization technology in the carcass cord processing of steel-belted radial tire was discussed. The results showed that the irradiation dose had a certain effect on the properties of the carcass
cord compound，cord and its fiber precursor and tire. Electron beam irradiation prevulcanization technology had broad application prospects，and it could play an important role in optimizing processes，improving production efficiency and tire product quality. In recent years，large domestic tire enterprises have equipped
electron beam irradiation equipment in the new construction or reconstruction projects of the carcass cord
calendering production lines of steel-belted radial tires，but the problem of the high failure rate needed to be
solved. |
