| Abstract: |
| Non-isothermal curing process of giant OTR radial tire was studied. The results showed that，compared with the traditional curing process，giant OTR radial tire cured with non-isothermal process（heating time/dwell time ratio was 1/1.07） had a lower degree of over curing and better physical properties，non-isothermal curing process could improve vulcanization uniformity and solve the problem that some parts were over cured seriously. By adjusting the heating time/dwell time ratio during non-isothermal curing process，properties and production efficiency of giant OTR radial tire were improved，and the energy consumption of the production process was reduced. |
