研究巨型工程机械子午线轮胎的变温硫化工艺。结果表明：与传统硫化工艺相比，采用变温硫化工艺（加热时间/保压时间比为1/1.07）的巨型工程机械子午线轮胎胶料过硫化程度降低，物理性能提高；变温硫化工艺能提高巨型工程机械子午线轮胎硫化均匀性，解决局部过硫严重的问题；采用变温硫化工艺，调整加热时间与保压时间比，有利于提高巨型工程机械子午线轮胎性能和生产效率，节约能源。;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
